The Siemens MS42 ECU was found in many BMWs including the E36 Z3, E46, E38 and E39.
This service is for you to send us your original ECU. We copy the core data from the ECU and copy it back to a replacement unit. This means your VIN, Immobiliser data and any coding’s will remain intact and is ideal for customers with faulty ECUs either due to water damage or another fault.
We keep replacement ECUs on the shelf and when your ECU arrives it will be cloned to a replacement and both units will be returned. The replacement ECU comes with a 3 month Warranty regardless of fault.
Customers must be aware in some rare circumstances some ECUs are beyond being able to be read due to damage (mainly water damage) and in these cases we will advise the best course of action. If we are unable to recover the data from your old ECU their is an inspection and admin fee of £60. Your ECU would be returned and the balance refunded.
