Hi, I'm having a weird problem with a replacement ECU in a 2009 Clubman. I Googled the fault code and I landed on this thread from another member with almost the exact same problem:

My car is also a manual transmission and may have received a donor ECU from an automatic. You had offered to use TeamViewer to check the vehicle settings and possibly change them to clear the fault. Is that offer still on the table, although my errors are slightly different:
3099 No Message EGS, Receiver DME, Transmitter EGS
5DF3 DSC Interface, DME/DDE Signal Fault
Please let me know if that's something you'd be willing to do. Thanks!
