Audi A6 4F0910655R Airbag ECU Crash Data Reset Service
Audi A6 4F0910655R Airbag ECU Crash Data Reset Service
After a collision, the Audi A6 airbag ECU locks itself — it stores crash event data and cannot be cleared with a standard diagnostic scanner, leaving the airbag warning light on permanently and the entire supplemental restraint system disabled until the module is reset at component level. The Vehicle Check offers a specialist Audi A6 4F0910655R airbag ECU crash data reset service by post — covering the whole of the UK — with a 3–5 working day turnaround and free tracked return.

What actually happens inside a locked airbag ECU?
During a collision, the airbag control module records deployment data — G-force readings, circuit fire events, pretensioner trigger states — and writes them to protected non-volatile memory. Once that crash data is written, the module enters a permanent fault state. It refuses all OBD-level clear commands and shows a live airbag fault on every scan. The module effectively considers itself spent. Clearing that data requires direct, component-level access to the internal memory — something that falls well outside what a dealer's diagnostic tool or a generic scanner can achieve.
That is precisely what TVC does. Using bench-level programming equipment, the team reads and clears the locked crash data from the 4F0910655R module, restoring it to a pre-accident, deployable state. The airbag warning light clears, and the SRS system functions as it should once the module is refitted.
Is part number 4F0910655R the right reference for my Audi A6?
4F0910655R is a unit-family number that spans a range of Audi A6 variants and production runs. The number on your own module's label is the definitive reference — always check it before ordering. TVC will verify the number against your unit as the first step of every job and will confirm suitability before any work is carried out. If your label shows a closely related suffix or a different variant, get in touch and the team will advise.
How does the mail-in service work, and how should I package the unit?
The process is straightforward. Remove the airbag ECU from the vehicle — it is typically located under the centre console or beneath the front seats, depending on the A6 variant. Once removed:
- Wrap the module in at least two layers of bubble wrap to protect the connector pins and housing.
- Place it inside a rigid cardboard box with additional padding — a module rattling in an oversized box is the most common cause of transit damage.
- Include a note with your full name, return address, mobile number, vehicle registration and a brief description of the fault (e.g. accident date, any codes read).
- Send by a tracked service to: Office 13, 25 Mollison Avenue, Enfield, EN3 7NJ.
TVC will email or call when the unit arrives, confirm the part number, carry out the crash data reset within 3–5 working days, and return the module by free tracked courier. You refit it, clear any remaining fault codes with your scan tool, and you are back on the road with a fully operational restraint system.
Why does mail-in beat going to a dealer for this job?
| Factor | TVC mail-in reset | Audi dealer replacement |
|---|---|---|
| Your existing module | Retained and reset — same unit goes back in | Discarded; new unit supplied at parts cost |
| Coding / variant matching | Reset module retains original coding for your car | New unit often needs dealer coding at additional charge |
| Turnaround | 3–5 working days door to door | Subject to parts availability — can run to weeks |
| Geography | Available to any UK address by post | Requires the car to be driveable to the dealer |
