Bought a used ECU from a breaker, scrapyard or eBay? We adapt it to your vehicle — VIN, immobiliser, key pairing, mileage alignment — all matched to your car. Cheaper than a dealer unit, and the car treats it as factory.
A used ECU from another car needs more than just plugging in — VIN, immobiliser, key pairing and mileage all need aligning to your specific vehicle. We handle every step so it behaves as a factory-fit unit.
A used ECU needs more than fitting — it needs your VIN, your keys, your mileage. Each step has to be done right or the car won't start, won't recognise the key, or will throw codes.
The complete job: VIN write, immobiliser deactivation, key pairing, mileage alignment with the cluster, fault codes cleared. The donor ECU now behaves as a factory-installed unit on your car.
Before you buy a used ECU, we'll check that the part number you're looking at will actually adapt to your car. Wrong donor = no go, and these mistakes can be costly.
The donor ECU still has the original car's VIN burned into it. We re-write yours, so every module on your car agrees with the ECU about which vehicle it's in.
The donor ECU is locked to its old keys. We deactivate the immobiliser data and re-pair to your existing keys — your car's keys keep working as before.
The donor ECU's stored mileage almost certainly won't match yours. We sync it to your cluster value so all modules agree, no warning flags raised on the next service.
Full module communication check, fault code clear, road test if needed. We don't consider it done until the car runs cleanly, starts first time, and shows no warning lights.

Bought a used ECU from a breaker. Dashtech adapted it to my car — VIN, key, immobiliser all sorted. Saved hundreds versus a dealer unit.
My ECU died, dealer wanted nearly £1,200. Bought a used one for £180 off eBay, Dashtech adapted it — car runs perfectly. Just like factory.
Checked the part number with Dashtech BEFORE buying. They confirmed it would adapt, then did the work. Saved me from a costly mistake.
Got a used ECU off Facebook for nearly nothing. Dashtech got it working with my keys in under three hours, all on the driveway.
Adapted my used ECU, mileage matched, no warning lights. Honest, friendly, knows his stuff. Booked again already for the wife's car.
Used ECU adaptation done at my workplace during my lunch break. Drove home like nothing had happened. Brilliant service.
