I have a 2005 GTI 1.8T and recently, only while idling, the engine has stopped. When I restart it cranks for a bit and then starts up in EPC mode. The battery is new. Someone mentioned in another thread maybe it's the MAF sensor. I'm not sure how old that sensor is and I never cleaned it. I noticed in EPC mode it seems to idle with higher rpm. I bought the car used a couple years ago. Is it probably the problem?
