Crash Data Reset — UK Mail-In Service

Your airbag light is on. The accident is long over. But your car still thinks it's in the middle of a crash — and that locked-up module is the reason. Post it to us. We'll fix it.

What Is Crash Data and Why Does It Lock Your Airbag Module?

Crash data is fault information written permanently into your airbag control module's memory the moment your vehicle detects an impact event — even a relatively minor one that didn't deploy the bags. The module stores voltage spikes, G-force readings and deployment signals as a hard fault, and from that point it refuses to function normally. No amount of clearing codes with a standard OBD scanner will shift it. The data sits at a deeper level, and without specialist equipment it simply stays there, keeping your airbag warning light illuminated and your SRS system offline.

This is why drivers all over the UK end up with a car that has passed a bodyshop repair but still has a lit airbag warning light. The bodywork is perfect. The module hasn't moved. The crash data is still sitting in there, flagging the event every time the ignition turns on.

How Does the TVC Mail-In Crash Data Reset Service Work?

It works exactly as you'd hope — straightforwardly. Remove the airbag module from your vehicle, package it securely, and post it to us at Office 13, 25 Mollison Avenue, Enfield, EN3 7LW. We receive it, bench-test the module, clear the crash data using our professional-grade programming equipment, verify the module is reading clean, and return it to you by free tracked delivery. Refit it, clear any remaining diagnostic codes, and your SRS system is back online.

If you're not confident removing the module yourself, check in with a local independent garage first — or if you're within 60 miles of Enfield, you're welcome to drive in and we'll handle everything on the spot. For everyone else across the country, the mail-in route is just as effective and considerably cheaper than any alternative.

Why Does Mail-In Beat the Dealer for Crash Data Reset?

The dealer's default answer to a stored crash event is a new module — which means a new part at main-dealer prices, programming fees on top, and a wait while they order it in. You could be looking at several hundred pounds before anyone's even touched a screwdriver, and that's before VAT. A remanufactured or secondhand replacement also has to be coded to your VIN, which is a separate job with a separate invoice.

Our crash data reset keeps your original module in your vehicle. There's no coding it to a new unit. No waiting for parts. No inflated labour charges. And because we work on the module directly with specialist bench equipment — not a generic OBD interface — we can clear data that a dealer's standard tooling won't even acknowledge. The savings are real and the turnaround is faster.

Which Cars Do We Reset Crash Data On?

Across our years in automotive electronics, we've worked on airbag modules from virtually every mainstream manufacturer sold in the UK — BMW, Mercedes-Benz, Audi, Volkswagen, Ford, Vauxhall, Toyota, Honda, Nissan, Renault, Peugeot, Citroën, Fiat, SEAT, Skoda, Kia, Hyundai, Land Rover, Volvo and more. Whether you're driving a 2010 Ford Focus or a 2025 BMW 5 Series, if it has an airbag control module, we almost certainly support it. If you have any doubt about your specific vehicle or module part number, give us a call on 0203 489 2610 before posting — we'll confirm compatibility in minutes.

Our team has been working in automotive electronics for well over a decade, and we've developed a hard-earned understanding of how different manufacturers store crash data — the difference between how a Bosch unit on a Vauxhall handles a deployment event versus how a Continental module on a Renault does. That specificity matters when you're working at firmware level, not just plugging in a cable and hoping.

How Do I Package My Airbag Module Safely for Posting?

Your airbag module is a circuit board in a plastic housing — it's not fragile in the way that glass is, but it does need a bit of protection in the post. Here's what we recommend:

• Wrap the module in bubble wrap — two or three layers is ideal. Pay attention to any exposed connector pins.
• Place it in a rigid cardboard box — not a padded envelope. The module should not be able to move around inside the box. Fill any gaps with scrunched paper or foam.
• Include a note inside with your name, phone number, return address, and your vehicle's make, model and year. This speeds things up enormously at our end.
• Use a tracked service — Royal Mail Tracked 48 or 24, or any courier you prefer. Keep the tracking number until you hear back from us.
• Send to: Office 13, 25 Mollison Avenue, Enfield, EN3 7LW.

We'll drop you a message as soon as the module arrives and again when it's on its way back to you.

What's the Turnaround Time?

Most crash data resets are completed and on their way back to you within 3–5 working days of arrival. In many cases it's faster — particularly for common Bosch, TRW and Autoliv modules where we have an established workflow. Return delivery is free and fully tracked, so you're not paying anything extra to get your module home. If there's ever a complication — an unusual module type or additional faults we spot on the bench — we'll ring you before doing anything, so there are never any surprise charges.

While your module is with us, it's worth knowing we also handle ABS module repair and ECU repair and cloning by the same mail-in process — so if your vehicle has other electronic gremlins alongside the airbag issue, we can often look at them all in one go.

Is the TVC Crash Data Reset Guaranteed?

We stand behind our work. If the crash data reset doesn't clear the fault, we'll investigate further and work with you to resolve it — we're not the kind of outfit that takes your money and stops answering the phone. We've built our reputation on repeat customers and word-of-mouth, and that only happens when the job is done right. Our Enfield workshop is a real place with real people, and you can call us any time on 0203 489 2610.
