    Hey Guys,

    Just wanted to share an experience last month, just a week before I was due to send the car for it's 3rd service at AB (around 34,000 kms service). I was driving at night and suddenly front right LED light failure error shown in dashboard followed by both front lights off and on again in split second. After a while, again the same error happen and this time whole dashboard switch off. All lights were out, AC stopped but luckily engine still running and steering is working. Within 2 seconds the system restarted and all lights came back, then error shows RFT sensor failure and DSC failure.

    Pull to the side of the road and stop start the car, everything back to normal. No further occurrence after that until i sent the car for service. Told the service guy what happened and they said will do a full diagnostic.

    After 2 days, they called me up (after completing the regular service) saying that my drivetrain CU has failed and have to order parts from Germany. Waited almost 2 weeks later and the part arrived. Now the car is back with me and all seems back to normal. This really lowered my confidence in my F30... :(

    Anyone else faced such a failure before? Do share your feedback,,,

    At times, it could just be a simple system glitch. Probable cause could be moisture from rain/water effecting the circuit

    Hmmm...I hope its not some design defect, we are living in rainy tropical zone. So far no more issues, but now I'm having the RPA and ABS failure warning popping up then going away after awhile...

    sigh...one thing after another...really stops you from enjoying this ride...
