Audi A6 4B0959655P Airbag ECU Crash Data Reset Service
Audi A6 4B0959655P Airbag ECU Crash Data Reset Service
After an impact — even a relatively minor one — your Audi A6's airbag ECU records crash data that locks the SRS system and keeps the airbag warning light on permanently. The airbags may not deploy in a future accident while that data remains stored. The fix is a crash data reset on the module itself, and that is exactly what this service covers.
The Vehicle Check offers a nationwide mail-in Audi A6 4B0959655P airbag ECU crash data reset — post your unit to our Enfield workshop, and we'll clear the stored crash data, bench-test the module and return it to you ready to refit, with free return shipping included.

What Does Crash Data in the Airbag ECU Actually Mean?
When your Audi A6 is involved in an impact above a certain threshold, the airbag control module — in this case the unit carrying part number 4B0959655P — writes crash event data to its internal memory. This is by design: it logs what happened so engineers can analyse deployment decisions. The problem is that the module then treats itself as a used, post-crash component. It raises a permanent SRS fault, the airbag warning light stays on, and the system will not arm itself correctly for future protection until that data is cleared.
A simple scan-tool reset from a garage will not clear crash data — that requires specialist bench work directly on the module's memory. That is what TVC does.
Is Part Number 4B0959655P Definitely the Right Module for My Audi A6?
The number 4B0959655P is a unit-family reference associated with Audi A6 airbag ECUs, but part numbers on SRS modules can differ by build date, market specification and optional equipment. The number on the label of your own unit is the one that counts. Before you send anything, check the label on your module and contact us to confirm — call 0203 489 2610 or use the website. We will tell you straight away whether your number falls within the range we service. We will never start work on a unit without that confirmation.
How Does the Mail-In Service Work — Step by Step?
The process is straightforward and designed to be as low-effort as possible for you:
- Disconnect your battery and wait a minimum of 20 minutes before touching anything SRS-related.
- Remove the airbag ECU from the vehicle. On the A6 it is typically located under the centre console. If you are unsure, a local garage or auto-electrician can remove it in minutes.
- Place your order on the live product listing so we know to expect your unit.
- Pack the module carefully. Wrap it in bubble wrap or foam, place it inside a rigid cardboard box, and fill any void with packing material so it cannot move. Place a note inside with your name, contact number and vehicle registration.
- Post it tracked. Royal Mail Tracked 48, ParcelForce or any courier that provides a tracking number is fine. Keep your receipt.
- We receive, bench-test and reset your module within 3–5 working days.
- Free return shipping — we send your unit back to you by tracked courier at no extra cost.
- Refit and clear any remaining scan-tool faults (non-crash-data faults) with a standard OBD reader.
Mail-In vs Dealer — Which Makes More Sense?
| TVC Mail-In Reset | Audi Main Dealer | |
|---|---|---|
| Approach | Crash data cleared and module returned to you | Typically supply and code a new replacement unit |
| Your existing module | Retained and reset — same part goes back in | Usually discarded in favour of new unit |
| Turnaround | 3–5 working days | Variable; parts availability can extend waits |
| Location required | None — post from anywhere in the UK or abroad | Must take vehicle to dealer |
Why Trust The Vehicle Check With Your SRS Module?
TVC is a specialist automotive electronics workshop with hands-on experience across a wide range of makes and systems — from DSG and Mercedes mechatronic units to BCM, BSI and FRM modules, clutch actuators and SRS airbag crash data resets across multiple vehicle brands. We work directly at component level on bench — not via scan-tool guesswork — and every unit we process is tested before it leaves us. We handle SRS modules from customers across the whole of the UK and internationally, all by tracked mail. This is what we do every day, not an occasional sideline.
The 4B0959655P is one of the Audi airbag ECU part numbers we regularly see, but as noted above, your label number is confirmed with you individually before any work begins. That is a straightforward step that protects both sides.
