How to Find Your Airbag ECU Part Number (UK Quote Checklist) | Reset My Airbag Home / Blog / Airbag ECU part number Quote checklist · UK postal · East Grinstead How to find your airbag ECU part number Published 27 August 2026 · Reset My Airbag, East Grinstead, West Sussex Direct answer: The number that matters is on a sticker on the SRS control module — the metal or plastic ECU in the car — not on the airbag in the wheel. Photograph the whole label square-on, send it with the registration, and we can quote a reset or repair. “It’s a 2016 Golf” is not a part number. Two cars that look identical often use different hardware. Key takeaways Quote the box in this vehicle, not a listing photo or a mate’s car. Registration helps; the label confirms it. Blurry photos waste a day. All digits, barcodes and indexes must be readable. Manufacturer pages list coverage — still send the sticker from your unit. On this page Where the ECU usually sits What to photograph What to send for a quote FAQs This is the identification page. It is not a crash-data explainer. For reset vs replace see repair vs replacement. Brand coverage: makes and models. Where is the airbag control module? It is a small control unit with a multi-pin connector, usually a printed label on the case. Typical locations (always confirm for that VIN / workshop data): under a front seat (very common) centre console / transmission tunnel passenger footwell / kick panel behind dash trim on some platforms It is not the clock spring, not the bag in the wheel, and not the crash sensor in the bumper. Disconnect the battery and follow SRS precautions before you lift seats or trim. If you are not set up for that, get a garage to photograph the label in situ. What the part number looks like — and how to shoot it On the sticker Why we need it Main OEM part number (often 10+ characters) Hardware family — reset compatibility Hardware / software index, 01 / 02, dash numbers Same “part” can be a different board Barcodes Backup if a digit is misread Make logos (Bosch, Autoliv, Continental, etc.) Supplier, not a substitute for the OEM number Photo rules that actually get a quote back the same day: whole sticker in frame, no flash glare, no thumb over the number, taken after wipe if the label is dusty. One close-up plus one of the whole ECU (connectors visible) is better than five unreadable shots. Do not copy a number off a used module you have not fitted. Do not invent a number from a parts catalogue “that looks right”. What to send Reset My Airbag Registration (and make/model/year if the VRM is new or personal) Clear photo of the ECU label Whether bags or pretensioners deployed, if known SRS codes if you have already scanned We quote by email or text from East Grinstead. Compatible crash-data work starts from £95. The module is posted in, worked on the bench, posted back tracked. Label photo + registration is enough to start. No booking until you accept the price. Get a quotation Frequently asked questions Where is the airbag ECU part number? On the SRS control module sticker in the vehicle. Not on the steering-wheel bag. Is the registration enough? It helps. The label is what we trust when the same model has more than one ECU. The sticker is damaged — can you still quote? Send the best photo plus registration and scan codes. Coverage may still be possible; some units need sight of the board. Should I send the module before you quote? No. Identify first. Post after you accept the quotation.

Airbag ECU Repair vs Replacement: When to Reset, Repair or Fit New | Reset My Airbag Home / Blog / Repair vs replacement Decision guide for garages & owners Airbag ECU repair vs replacement: when to reset, repair or fit a new module Updated 27 August 2026 · Reset My Airbag, East Grinstead · UK postal SRS ECU service Direct answer: After a collision, replacing the deployed bags and pretensioners does not finish the job. The airbag control module (SRS ECU) often still holds crash data, or it has an internal electronic fault. If that original module is serviceable, a specialist reset or repair is usually better than a dealer replacement — you keep the vehicle’s existing coding and avoid a used ECU that may be crash-locked or VIN-matched to another car. Replacement is the right call only when the module is physically damaged, beyond economical repair, or specified as replace-only. Key takeaways Reset, repair and replacement are three different jobs — not three names for the same service. A reset clears stored crash data on a compatible original ECU. It does not fix bags, belts, sensors or wiring. Repair is for no-comms, memory and power-supply faults inside the module. A new or breaker ECU often needs coding and can bring someone else’s crash lock with it. Quote from the part number on the label, not from the car looking “the same”. On this page The three options Why the original ECU usually wins When replacement is the right call Used and breaker modules What to check before you send the module Cost, coding and turnaround UK postal process FAQs This page is the decision guide: reset, repair, or replace the SRS ECU. If you need the crash-event explanation, use Can airbags be reset after an accident? If the bags are already fitted and the lamp is still on, use why the light stays on after airbag replacement. MOT lamp rules sit in Airbag warning light on: causes and MOT rules. Reset, repair or replace — they are not the same The airbag control module monitors bags, pretensioners, crash sensors, occupant detection and the SRS network. After a significant impact it can store crash data, lock itself, or suffer an internal electronic failure. Dealers will often quote a new module. That is one option. It is not automatically the best one. Compare the three paths for a serviceable vs failed SRS ECU. Path Use it when What you keep What it will not do Crash data reset Compatible original ECU, crash-locked, otherwise healthy Original hardware, existing coding Repair bags, belts, sensors or a dead ECU Module repair No communication, memory, power or component-level damage Original unit after bench repair Help if the board is physically destroyed Replacement ECU Unrepairable, water/impact damage, or manufacturer replace-only A different unit — coding usually required Guarantee a used module is clean of crash data Airbag module reset A reset is crash-data removal on a compatible SRS ECU, on the bench, with specialist equipment. The module is inspected first. If it is the wrong hardware, physically damaged, or has an internal fault, it is not a reset job. Airbag module repair Repair is for the ECU that will not talk, has corrupted memory, a power-supply fault, or failed internal components. Treating that unit as “just clear the crash data” wastes time and leaves the lamp on. Why keeping the original module is usually better The original ECU already belongs to that car. On many platforms it carries vehicle-specific coding. Fit a new or used replacement and you may also be buying programming time, VIN matching, and the risk that the donor unit is still crash-locked. If the original module can be reset or repaired, you typically: avoid dealer-level module prices reduce coding and configuration work after refit keep a unit that has already lived on that vehicle’s network Compatible resets at Reset My Airbag start from £95. Exact price depends on part number and fault — send the label, not a guess. When replacement is the honest answer Replace the ECU when: the housing, connector or board is impact-damaged, burnt or water-logged bench inspection shows the fault is beyond economical repair that hardware family is not supported for reset or repair the manufacturer process for that car is a new coded module only A replacement still has to be the correct part number and, on many cars, correctly coded. “Any airbag box from the same model” is how people buy a second crash-locked unit. Used airbag ECUs from breakers and online listings A second-hand SRS module is not a shortcut. It may still contain the donor car’s crash data. It may be a different hardware index with the same plastic shell. It may need coding you cannot complete with a basic scanner. If you already bought a used module and the lamp is on, diagnose it as its own job. Do not assume a reset of the original unit is no longer worth doing — the original is often still the cleaner path. What must be right on the car before the ECU is reset Resetting the module does not repair a bag that has fired, a pretensioner that has fired, a crushed sensor or a broken SRS loom. If those faults stay, the lamp comes back. Scan first, then send the ECU. Record SRS fault codes before anything is cleared. Confirm which bags and pretensioners actually deployed. Replace or repair those pyrotechnic parts correctly. Check crash sensors, connectors, battery supply and occupant detection. Photograph the ECU label (part number) and note the registration. Then decide reset, repair or replace from that evidence — not from the warning light alone. The UK MOT inspection manual treats an SRS malfunction indicator that shows a system fault as a Major defect. Clearing a lamp without fixing the system is not a repair. How much you save — and why there is no one price There is no honest single figure. Cost depends on make, exact SRS

Airbag Light Still On After Replacing Airbags? UK Diagnostic Guide | Reset My Airbag Home / Blog / Light still on after bags replaced UK SRS diagnosis · East Grinstead postal Why is my airbag light still on after replacing the airbags? Updated 27 August 2026 · Reset My Airbag, East Grinstead, West Sussex · UK-wide tracked return Direct answer: New bags do not reset the Supplementary Restraint System. The SRS ECU often still holds crash data, or something else that fired or broke is still in circuit — pretensioners, impact sensors, clock spring, occupancy mat, a wrong-part bag, or a connector knocked off during the strip. Scan the airbag module with a proper SRS tool before you send the ECU. If the only remaining story is crash data on a serviceable original module, that is a specialist bench reset, not a dealer box. Key takeaways Fitting airbags is one job. Signing the SRS off is another. A basic OBD engine reader will not tell you why the lamp is on. Record codes first. Clearing them is not a diagnosis. Do not post the ECU while pretensioners or sensors are still faulty — the lamp will come back. An SRS malfunction lamp is a Major MOT defect in the UK. On this page What the SRS actually did in the crash Cause vs what to do How to find the remaining fault OBD2, battery disconnect, used modules MOT FAQs This page is for the car that already has new bags in and the lamp still lit. If you are choosing reset versus a new ECU, use airbag ECU repair vs replacement. MOT lamp categories in more depth: airbag warning light, causes and MOT rules. What happens when airbags deploy In milliseconds the SRS can fire driver, passenger, side, curtain or knee bags and the seat-belt pretensioners. The airbag control module (SRS ECU) logs that event as crash or deployment data. Swapping the visible bags does not wipe that memory. It also does not fix a pretensioner that fired and was left in the car. Why the lamp is still on — cause versus next step Likely cause Typical clue Do this Crash data still in the original ECU Bags and belts already correct; codes mention crash / deployment / stored event Photograph the ECU label, send the original module for bench reset if compatible Pretensioner still fired or open circuit Belt locked, burnt connector, B-pillar or buckle codes Repair or replace the pretensioner. Do not reset the ECU first Impact / satellite sensor Front, side or satellite sensor codes; crush in bumper or sill Test the sensor and loom. A code is not a parts list Wiring or connector Intermittent lamp after interior strip; codes change when a seat is moved Check under seats, dash, yellow SRS plugs, clock-spring connector Wrong or incompatible bag Lamp appeared the moment the new bag was plugged in Match part number, year and trim — similar plastic is not the same bag Clock spring Driver bag / horn / steering-angle codes after airbag or column work Inspect the clock spring; do not keep clearing the code Occupancy / seat mat / seat position Passenger bag codes with no dash-bag work Diagnose the seat circuit. Recalibration may be required on some cars ECU internal fault (not just crash data) No communication, internal failure, water or impact on the module That is repair or replace — see the repair vs replacement guide Used or new ECU fitted without coding Lamp after a breaker or dealer module swap Coding/VIN match, or put the original back and reset that instead Crash-data reset only clears what is stored in a healthy compatible ECU. It will not hide a fired pretensioner, a crushed sensor or a bag with the wrong resistance. How to find out why it is still on Scan the SRS, not the engine. Use a tool that opens the airbag control unit. Write the codes down before anyone presses clear. List what actually fired. Driver, passenger, curtains, pretensioners, sensors already replaced — so you are not guessing. Diagnose each live code. The component named in the text is a starting point, not an order form. Check the loom. Decide if crash data is all that is left. If hardware is correct and the module still reports a stored crash event, the original ECU can often be reset on the bench in East Grinstead and posted back UK-wide. Repair the rest, then rescan. If you clear codes and the lamp returns in the same ignition cycle, the fault is still live. Send registration, ECU part number (photo of the label), which bags fired, and the SRS codes via the quotation page. Get a quotation OBD2 scanners, disconnecting the battery, second-hand modules Can I clear it with a cheap OBD2 reader? Usually no. Those tools read the engine. SRS needs an airbag-capable interface. Even then, crash data is often locked in the ECU and will not wipe from the OBD socket. Will disconnecting the battery reset the light? No. The crash record lives in the module. Battery disconnect does not repair pyrotechnics or sensors. Can I use a second-hand airbag module? High risk: donor crash lock, wrong hardware index, VIN coding. Keeping and resetting the original unit is usually cleaner — full comparison on repair vs replacement. Is an airbag light an MOT failure? Yes, if the SRS malfunction indicator shows a system malfunction — that is a Major defect in the MOT inspection manual for cars and passenger vehicles. A lamp that only shows the passenger airbag has been switched off on purpose is treated differently. Do not present the car until the system is actually repaired. What to send us if the remaining job is the ECU Reset My Airbag works with private owners, garages, bodyshops and accident repair centres across the UK. Modules come into East Grinstead, West Sussex, and go back tracked. Make, model, year and registration Photo of the SRS ECU part-number label

Airbag Warning Light On? Causes, MOT Rules & What To Do in the UK | Reset My Airbag Home / Blog / Airbag light, MOT and causes UK MOT · SRS lamp · East Grinstead Airbag warning light on? Causes, MOT rules and what to do in the UK Updated 27 August 2026 · Reset My Airbag, East Grinstead, West Sussex · UK postal SRS ECU service Direct answer: The airbag / SRS lamp means the Supplementary Restraint System has logged a fault — from a loose seat plug to crash data in the ECU. It is not normal if it stays on after the ignition self-test. In the UK, an SRS malfunction indicator showing a system malfunction is a Major MOT defect. Scan the airbag module, repair the real cause, then clear codes. Do not wipe the lamp the night before the test and hope. Key takeaways Brief lamp at ignition on is normal. Lamp that stays on, comes on while driving, or returns after a clear is a fault. MOT fail = SRS malfunction lamp. Passenger bag “off” switch lamp is a different rule. Not every SRS lamp means the ECU needs a crash-data reset — especially if the car has never been in a smash. A cheap engine OBD reader is the wrong tool. Drive it if you must, but do not assume the bags will fire next time. On this page What the lamp means MOT rules (the bit testers actually use) Causes — crash and everyday Can you drive? How you actually fix it FAQs This is the MOT and general-causes page. Bags already replaced and the lamp still on: diagnosis after airbag replacement. Reset versus a new module: repair vs replacement. What the airbag warning light means Dash wording varies: airbag icon, SRS, a seated figure, “Airbag Fault”, “Restraint System Fault”. At key-on the lamp should light for a self-test, then go out. If it stays, flashes, or returns after someone “cleared it”, the control unit has a stored or live fault. SRS is the Supplementary Restraint System: bags, pretensioners, crash sensors, occupancy, clock spring, looms, and the airbag ECU. One open circuit in that network is enough to keep the lamp on. Is an airbag light an MOT failure in the UK? Yes — if it is a malfunction lamp. The MOT inspection manual for cars and passenger vehicles classifies an SRS malfunction indicator that indicates a system malfunction as a Major defect. The vehicle will not pass with that present. The tester is looking at what the lamp is telling you, not whether you dislike orange icons: What you see Typical MOT view SRS / airbag malfunction lamp on (system fault) Major defect — fail Passenger airbag deliberately switched off (status lamp only) Not treated as an SRS system defect by itself Lamp comes on at ignition then goes out Normal self-test Clearing a code in the MOT car park is not a repair. If the fault is live, the lamp comes back — sometimes before the tester has finished the brake test. Common causes — including when there was no accident Cause When it shows up First move Crash data in the SRS ECU After a collision, even once bags are fitted Scan; if that is all that remains, original ECU reset Fired pretensioner or open bag circuit After a smash, or a botched repair Fix the pyrotechnic / circuit — do not reset first Connector under the seat After the seat was slid, valeted, or a child seat fitted Inspect yellow SRS plugs and occupancy wiring Occupancy / passenger mat Passenger bag codes, no crash history Diagnose the seat; some cars need calibration Clock spring Driver bag / horn / buttons after steering work Inspect the column cassette Impact sensor or loom After bumper, sill or water damage Test sensor and wiring, not “sensor = new sensor” Low battery / jump start Lamp after a flat battery Scan anyway — voltage codes exist, guessing is not a fix ECU internal fault No comms, water, impact on the module Repair or replace — not a crash-data-only job Unknown history on a used car Bought with the lamp on, or it appears after a week Full SRS scan; assume nothing about previous repairs Can you drive with the airbag light on? The engine will usually still run. That is not the same as the car being safe. While the SRS is in fault, you should not assume bags or pretensioners will operate in another impact. Get it scanned. If an MOT is due, get it repaired first — a Major defect is a fail, not a warning advisory. How you fix an airbag warning light There is no universal “reset the light” trick. Sequence: Read SRS codes with a tool that talks to the airbag ECU. Record them before anyone clears them. Investigate that circuit — bag, belt, sensor, plug, clock spring, occupancy, or the module itself. The code names a circuit, not always a dead part. Repair the hardware. Pyrotechnics and SRS looms are safety-critical. Crash data only if that is what is left after an accident repair. Compatible original modules can be posted to East Grinstead for bench reset and tracked UK return. Refit, rescan. If the lamp returns on the same cycle, the fault is still live. Bags already in and lamp still on — use the step-by-step diagnosis article, not a second copy of this page. If the scan shows crash data on a serviceable original ECU, send the part number (photo of the label), registration and codes. Quotation by email or text. Get a quotation OBD2, battery disconnect, DIY clears A supermarket OBD dongle is for engines. Crash data often cannot be erased from the socket even with a dealer-level tool. Disconnecting the battery does not wipe the ECU and does not repair a fired pretensioner. If the lamp comes back after a clear, stop clearing it. Never assume every SRS lamp needs a module reset.

Can Airbags Be Reset After an Accident? UK Module Crash Data Guide | Reset My Airbag Home / Blog / Can airbags be reset after an accident? Crash data · Original ECU · UK postal Can airbags be reset after an accident? Updated 27 August 2026 · Reset My Airbag, East Grinstead, West Sussex · Tracked return UK-wide Direct answer: The bag that fired is not reset. It is replaced. The airbag control module (SRS ECU) can often be professionally reset after a crash if it is physically sound and the hardware family is compatible. That job is crash-data removal on the original unit — not a dash-light trick, and not a substitute for new bags or pretensioners. Key takeaways People say “reset the airbags”. They mean the ECU. The cushion is scrap once it has fired. Crash data often will not clear with a garage OBD scanner. Not every module can or should be reset — damaged or internally failed units are a different job. The ECU can leave the car. The rest of the SRS cannot be ignored. Compatible resets at Reset My Airbag start from £95; quote from the part number on the label. On this page Bag vs module — what “reset” means What crash data is (and why a scanner fails) When a module can be reset Postal reset without the car Cost and turnaround in the UK FAQs This page answers can it be reset after a crash. Lamp still on after the bags are in: diagnosis after replacement. Reset versus a new ECU: repair vs replacement. MOT lamp rules: warning light and MOT. Can deployed airbags be reset? Part After a deployment Airbag (the cushion / module in the wheel, dash, curtain) Replace. It is not reset and reused. Seat-belt pretensioner Repair or replace if it fired. Airbag control module (SRS ECU) Often crash-data reset on the original unit if it is undamaged and compatible. Sensors, clock spring, looms Diagnose individually. A reset does not fix them. The ECU watches the system and, in a hard enough hit, stores crash or deployment information. That memory can keep the SRS lamp on after the visible parts are new. What is airbag crash data — and can a scanner clear it? Crash data is collision / deployment information written into the SRS control unit. Exact content depends on the car. The practical result is the same: codes stay, the lamp stays, and a standard OBD tool often cannot wipe it for good. A proper SRS scanner is still essential — it tells you whether you are looking at crash data or a live hardware fault. Clearing a trouble code is not the same as clearing crash memory. If the lamp returns, you have not finished the repair. Disconnecting the battery does not erase crash data. Can an airbag module be reset after an accident? Yes, many can — if the module is the right hardware, the stored event is the sort we can clear, and the board is not smashed, wet, or electronically dead. We decide from: manufacturer, model, year exact part number on the label type of stored crash data physical and electronic condition of the unit Not every ECU should be reset. Internally failed modules need repair or replacement — that decision sits on the repair vs replacement page. Resetting the ECU will not turn the lamp off if bags, pretensioners, sensors or wiring are still wrong. Will a reset kill the light when crash data was the only remaining fault? Yes. That is the job. Do not “reset it yourself” with a code wipe or a YouTube trick on a live SRS system. Pyrotechnics and specialist memory access are not DIY. How a UK postal reset works — the car stays with you Scan first. Repair fired bags and pretensioners. Photograph the ECU label. Disconnect the battery and remove the module using proper SRS procedure. Pack it so connectors cannot crush. Include your return address. Tracked post to East Grinstead, West Sussex. We identify the part, inspect it, and reset crash data if it is suitable. Tracked return. You refit. You scan the whole SRS again before MOT or customer handover. That is why bodyshops and private owners across the UK use a mail-in service: the vehicle does not travel, the original ECU does. Send registration, a photo of the SRS ECU sticker, which bags fired, and any SRS codes. Quotation by email or text — no booking until you accept. Get a quotation How much, how long, what else might need replacing Price depends on part number and whether it is crash data only or an electronic repair. There is no honest one-size UK tariff. Compatible crash-data work starts from £95. Typical bench turnaround on many units is same day or 24–48 hours once the module is here, plus postage each way. Other parts that often need attention after a smash: driver/passenger/side/curtain bags, pretensioners, belts, crash sensors, SRS plugs, clock spring, occupancy, dash crash structure — and only then the ECU. A module reset is not a shortcut around those. An SRS malfunction lamp is a Major MOT defect if it shows a system fault. Detail on the MOT page. Do not assume bags will fire in the next hit while that lamp is on. Frequently asked questions Can airbags be reset after an accident? The fired bag is replaced. The SRS ECU can often be crash-data reset and reused if it is undamaged and compatible. Can an airbag module be reused after a crash? Yes, in many cars, after a professional reset of the original unit. Depends on hardware, condition and stored data. Does the module need replacing because the bags deployed? Not automatically. Deployment is why crash data is there. Replacement is for a dead or unsupported ECU. Can an OBD scanner clear crash data? It may clear ordinary codes after a repair. Crash memory usually needs a specialist bench. If the lamp returns, you are not done.
