Which ECUs are you trying - they should have a part number on, e.g. 0 261 200 405.

If the car has the EWS system then you need to also make sure that the new ECU also has the corresponding EWS box and the key.

M52 ecu's are not interchangable unles ews gear that coresponds to the new Ecu is used.
M50 ecu's are interchangable though

Maroon label M50 ECU = No EWS.
Silver label M50 ECU = EWS.

They are directly interchangeable.
