48V Mild-Hybrid · Crash Data Reset · South Wales
Hybrid battery locked after a collision, or won’t wake up after the car’s been standing? Many 48V mild-hybrid battery modules store crash or fault data and lock themselves as a safety precaution — even when the battery itself is perfectly fine. We reset and repair these modules, restoring your vehicle to full working order without the cost of a new battery from the dealer.
We cover a wide range of mild-hybrid brands including Audi, Porsche, Mercedes-Benz and Volvo, among others — get in touch with your make and model and we’ll confirm we can help.
Why It Won’t Just Reset Itself
Much like an airbag SRS module, a 48V hybrid battery module can store a crash or fault event in a protected memory area — a deliberate safety feature that stops the battery operating again until it’s properly inspected and reset.
Crash and fault data is written to a protected area of the battery module. Standard OBD tools — and many professional-grade scanners — cannot access or clear this data. Specialist equipment is required.
In most crash-lock and flat-battery cases, the cells themselves are undamaged. It’s the software lockout — not the hardware — that’s stopping the battery from working.
Without the specialist equipment to reset the module, dealers frequently quote for a full replacement battery — which can run into thousands of pounds when a reset would have solved it.
We access the module, clear the crash or fault data, recharge and verify the battery is working correctly — restoring your original battery at a fraction of replacement cost.
