Car is a 2011 Yeti 2.0TDi SE DSG 4x4, 59,000 miles. Has been totally reliable over last 6 years, but then a few days ago refused to start. Engine spinning over freely, just not firing. After fiddling with the key, it did eventually start and has been starting and running perfectly ever since. Ran a VCDS scan which brought up lots of error codes for the time of the failure to start. These mostly involved "01314 Engine Control Module, 004 - No Signal/Communication - Intermittent". But the engine itself showed no faults, in spite of the summary saying "01-Engine - Status: Sporadic communications error 1000". I saved the scan (of course) and cleared the fault codes, and am now waiting for the problem to happen again Meanwhile, I removed the ECU (which I assume is the same thing as the Engine Control Unit), after a struggle. (Managed to unscrew those wretched security screws with the aid of water-pump pliers - not a method I've seen suggested before). There was no sign of water entry to the connectors, and all the contacts looked bright and clean. So put it back together and now waiting for the problem to happen again, Not sure what else I can do. Hoping desperately not to have to throw myself on the mercy of the dealers. I can post the complete scan if required, but didn't want to clutter up the forum. Would be very grateful for any suggestions.
