Please help, my car crank but refused to start. Before now the car will neither crank nor start, the key light was crossed. So I bought another complete control unit and fixed. Now the car will crank but not start. These are the fault codes I got: 2F45 DME: Interface, immobilizer-DME
2E7C BSD data bus Communication fault
2EEA: Temperature sensor cooler outlet, signal
2AD0 No message from transmission control unit, receiver DME, transmitter EGS/SMG/DKG

Hello,

It looks like that you have a DME-EWS synchronization issue. Did you install a new DME or a used but virginised unit? If yes then you need to synchronize the new(used) DME with the EWS. This can only be done using specialized software.

If you have installed a used DME from another vehicle without it being virginised then you will need to install the EWS and use the donor vehicles keys too.

Please see link below how to synchronize DME-EWS, using a virginised DME

Please let us know how you get along.

Cheers, Boris
