BMW E36 M3 & Z3M MSS50 DME Cloning Or EWS Delete

The service that we offer is for the Siemens MSS50, these control units are fitted to the BMW E36 M3 and the early Z3m running the Euro S50 engine.

Sadly, DME control units are no longer available so failures can result in a immobilised vehicle with no plan to repair. Most of the failures we see of this MSS50 control unit is a consequence of a failed ignition coil that blows the coil pack driver on the PCB, these are no longer available to purchase as a component and some of the time damage the DME’s PCB beyond repair.

We can clone your original MSS50 DME’s data to a donor (this would need to be sourced yourself). We also offer a EWS delete service to completely remove the EWS function from the DME. This is especially useful for engine swaps, when a EWS control unit has failed or when your original data is unrecoverable from your old DME. 

We only flash these ECU’s on the bench so no vehicle is required. This is ideal for customers that are further away or are using the engine in another vehicle or a conversion (we simply require the DME removed and we can complete the required service).

The cost of this service is £150 + VAT.
