Audi A6 4F0910655Q Airbag ECU Crash Data Reset Service

After a collision — even a minor one — the airbag ECU in your Audi A6 records what happened and locks itself. The SRS warning light stays on permanently, the airbag system is disabled, and no scanner can simply clear the fault because the crash data is written at a deeper level than ordinary diagnostic codes. The unit needs specialist attention to restore it to a fully operational state.

The Vehicle Check offers a crash data reset service for the Audi A6 airbag ECU bearing part number 4F0910655Q, carried out at our Enfield workshop and available to customers anywhere in the UK (and internationally) via a simple mail-in process. Post your module to us, and we'll have it back with you in 3–5 working days.

What does crash data locked in an Audi A6 airbag ECU actually mean?

When the SRS system detects a deployment-level event, it writes a permanent fault record — often referred to as crash data — directly into the module's memory. This isn't a standard DTC that resets with a scan tool; it's a hardware-level lock that prevents the airbag system from arming again. On the Audi A6, this typically presents as a solid airbag warning light on the instrument cluster, and in some cases the system will log codes related to the SRS module status. The only fix is to have the crash data cleared at the module level by a specialist with the right equipment and software access.

Replacing the airbag ECU with a used unit from a breaker is one route people consider, but a secondhand module often carries its own crash history, and it still needs to be coded to the vehicle. Resetting your original unit is the cleaner, faster and more cost-effective path in most cases. See our full crash data reset service range for more vehicles and modules.

Is part number 4F0910655Q definitely the right one for my car?

Part number families like 4F0910655Q can span more than one vehicle or production variant — the same hardware revision sometimes appears across different models or build years within a manufacturer's range. The definitive check is always the label on the physical unit removed from your car. Before any work begins, TVC will confirm the part number on your unit matches what we're set up to service. If there's any doubt, just call us on 0203 489 2610 or drop us a message and we'll advise before you spend anything on postage.

This attention to part-number verification is part of what separates a focused electronics workshop from a generalist garage. TVC works with Audi, VAG and a wide range of other marques across modules including mechatronic units, clutch actuators, and body control and footwell modules — electronics is the whole business, not a sideline.

How does the mail-in process work, and what's the safest way to package my airbag ECU?

The mail-in process is straightforward and used by customers across the UK as well as from overseas. Here's how it works:

1. Place your order at the live product listing so your job is logged in our system.
2. Remove the airbag ECU from the vehicle — it's usually located under the centre console or beneath a seat. Disconnect the battery at least 20 minutes before you begin to allow any capacitor charge to dissipate.
3. Package it carefully. Wrap the module in a couple of layers of bubble wrap, then place it inside a rigid cardboard box with padding on every side. The unit should not be able to shift around inside the box.
4. Post it tracked to Office 13, 25 Mollison Avenue, Enfield, EN3 7NJ. Keep your proof of postage and the tracking reference until we confirm receipt.
5. We carry out the reset, bench-test the unit, and dispatch it back to you via free tracked courier within 3–5 working days of receipt.

That's it. No dealership appointment, no lengthy wait for a parts order, no van-down time beyond the postage transit days.

How does sending it to TVC compare with going to a dealer?

Why trust TVC with your Audi's airbag ECU?

The Vehicle Check is a UK automotive electronics specialist with hands-on experience across a broad range of vehicle makes and module types — from VAG mechatronic units and Mercedes 9G-Tronic systems through to SRS airbag modules, body control modules and engine management hardware. Crash data work on Audi SRS modules is an established part of what we do, alongside services you can explore across our crash data reset collection. When your module arrives, it's bench-tested before and after the reset — not simply plugged in, cleared and boxed up.

Customers post units to us from across the UK, from the Channel Islands and from continental Europe. The mail-in model exists precisely because specialist electronics work shouldn't be limited to whoever happens to live near a particular workshop.
