Hello guys, I have an issue causing me headache. I got overvoltage probably caused by ignition coils, everything was shut off, changed alternator (as i didn't know what caused overvoltage) everything was ok, after 200km happened the same. Plugged in my old oem ignition coils, drove back home, then bought new delphi coils, car is driveable, everything seems fine except some hickups under load on low rpm, then i saw my voltage got low, around 12.3v while driving. Pressing brake - 14.7v come to stop 13v, after opening and closing doors ir gets back to 14v. Changed ibs sensor, everything was perfect for that day. I started the car in the morning, again 12+v. Unplugged ibs, 14.3v all the time so alternator is working, only thing i noticed there were no fault in dme for ibs sensor being disconnected. Tried to disconnect oil sensor and waterpump, voltage is still crazy, but there are faults in dme for those two. Is there a possibility that my dme got fried after overvoltage and now is going crazy? Has someone experienced this before? Sorry for my english,
