A replacement ECU from the scrapyard won’t start the car — it’s locked to the original vehicle’s immobiliser. And your main dealer will tell you to buy a new one. We do the alternative: clone the original ECU to the replacement, or program the replacement to your vehicle so it works exactly like the original.
It’s the kind of work that saves you thousands — and for VAG cars, it’s very much our speciality.
What we can do
- ECU cloning — full bit-for-bit copy of your original ECU to a replacement unit. Immobiliser, keys, tuning all preserved.
- ECU programming / flashing — load the correct software, data set and coding onto a replacement ECU.
- Immobiliser off (IMMO delete) — for motorsport, rebuild, or retrofit scenarios. Legal uses only.
- Adaptation learning — teaching new keys, new components, new sensors to the vehicle.
- Component protection removal — see our dedicated page.
- ECU reset after repair — clearing ghost faults and re-learning idle / throttle adaptations.
Why main dealers won’t do this
Main dealers’ standard policy is to sell you a new ECU rather than clone or reprogram a used one. That’s a commercial decision, not a technical one — the equipment exists, but the aftersales margin is better on new parts.
Because we’re independent specialists, we’ll happily clone a perfectly good used ECU to your car, saving you anywhere from £400 to £2,000 depending on the model. Same result, fraction of the cost.
Which ECUs we handle
VAG engine ECUs (EDC15, EDC16, EDC17, Simos, Bosch ME, MED, MEV), TCUs, ABS modules, airbag modules, instrument clusters, comfort modules — if it’s got a chip in it, we can probably work on it. Most other makes too.
