Have read through your posts and the useful comments by other Buddies on here. Can you answer a few questions for me....
Why did you change the BECM?
Is the new BECM a newer or older version of the original..post the part number, it will be AMR**** or YWC****** ?
Was the replacement BECM programmed to your car? It could have the original EMS code (Unique Engine ecu code still logged) and this needs to be the same as the one stored in your engine ecu...UNLESS you had the matching engine ecu with the BECM package and fitted it.
Did the new BECM come from a petrol or diesel car?
The BECM programme must be matched to one of the following engine choices, Early EDC (Diesel), Late EDC (Diesel), Petrol GEMS, Petrol Motronic (Thor). If the incorrect type is logged, the car will not run. It could be that the new BECM has the alarm and immobiliser functions disabled. To be honest, I feel that if hopefully, you still have the original BECM that it be sent to have it's settings read and duplicated or "Cloned" into your new BECM with either the new keyfob coding or the original...your choice.
The engine EMS code will still be stored in your old BECM, or if you don't have it, can be retrieved from your engine ecu by Faultmate/Rovacom/Test Book.
Synchmate will only work if the EMS codes match in the BECM and engine ecu's.
Finally, Have you checked the condition of the fusebox in the engine bay? If not, could be worthwhile removing it and inspecting the interior for signs of damage..information on this at

Let us know how thing go or with the answers to the above queries.
