I have mkv gti, Sunday while accelerating from a light my car least all power. Steering and breaking were not affected just read 0 rpm. I pulled over and attempted to restart my car. My car would not start. There was no fault codes or lights/warnings. After a couple minutes the car started and drive fine. There is now a low drone that follows the rpm's. When the rpm's increase the noise gets louder. There was also a little oil on top of the valve cover after this happened. I had just changed the oil the day before and it was not on the valve cover before this incident. Other than the drone there is not indication of something wrong. Anyone ever encounter this or have any idea why my car shut off and now had a drone while driving? My cam follower wore through not to long ago and I'm replacing the fuel pump due to lack of performance, I think the wear through damaged the piston on the hpfp. Not sure if that could have been the culprit of the shut down. Thanks for any help.
