    M52B25 into E36 compact EWS problem

    Hi everyone,
    I have swapped an M52B25 engine from E36 compact (05/1998) into my E36 compact with M43TUB19 engine (10/1999).
    I also swapped the DME and EWS from m52 into the car but the engine wont crank and the EML light stays on all the time.
    As far as I know the M52B25 is EWS 2 and M43TUB19 is EWS 3D. Is there any solution to this problem?
    I was thinking about reprograming the M52 DMU with an EWS delete but I am not sure if that is going to solve the problem.
    Appreciate every help I can get...
