Onumara Posted May 10 Share Posted May 10 Hello there people I find myself here today after what i would consider at this point a "traumatic experience" in my A3 The car is a 2003 A3 8P 2.0 FSI with soon to be 330k km, and am having quite serious issues with it. I had oil-water mixing, immediatly thinking my head gasket was done for, which prompted me to replace it myself, which was tedious but got done for in about a month or so Though it was actually not the culprit, as the head gasket was actually fine, but a gasket in the oil cooler that had to be replaced and was the cause of the oil water mixing I had the head rectified while i was at it, had an injector break because of it but found one quite cheap Quite a bit annoyed, i was finally done about a week ago with the car, and started enjoying it again, quite a singing thing with the exhaust i put on it and not slow either, very happy with the result, just until towards the end of the test drive. Letting the car warm up, finally getting some revs in, i get back home with a big smile on my face just until the car stalls right in front of my house, and doesn't restart until about 3 or 4 minutes of waiting, after what it goes back on without any strange noise I look past this little fluke, and go about the week of work when i take it back for a spin. The car feels great still, no rough idle, warms up nicely, cooling fans working properly in temps, revs beautifully and pushes out all of its healthy horses, after some driving though, i get a check engine light but no symptoms in engine sound or feeling, i scoff it off and go about the day knowing some sensors are to be replaced and it must be just that, after what i also get a red battery warning which is odd as i charged the battery back to full the day before this drive and the alternator was still working. All is good again, the car drives nicely until late at night on the way home, the car suddenly stalls like it did after the first test drive with a daunting Red oil pressure warning, where i litteraly shat myself. Having made all the basic maintenance after all the jazz with the head gasket, i knew oil, coolant and all was good, so looked for traces of oil in the engine bay and on the roads i've driven. Nothing in the bay, nothing on the roads, the oil was there so no way i had an oil leak somewhere. I nurse the car back home, waiting for it for a while, driving it very slowly and stalling about 4 times on the way back home, gladly it was not too far, about 3 km. All the while the check engine mentionned before was gone, the red battery issue was coming on and off but stayed mostly on and the car always stalled for lack of oil pressure or i hope not actually and it's just the sensor that's !Removed!. Finally got it back home, car had one misfire towards the end and started running rough, let it sleep for the night and started it again the day after to be greeted with an uneven and rough idle with very few but present misfires, almost the same as when i had found out about the !Removed! injector earlier. Oil level is fine, oil itself seems fine too (clean), no smoke coming from the exhaust, the battery symbol still on and the check engine gone, i am now wondering what the hell just went wrong with car, and am asking for you guys's insight I think and pray that it is just a sensor that went awry, and some clues do point towards this, like how the rev counter was locked at 6k at some point and only came back when i last stalled it the night and waited 15 mins this time, like some wiring or the sensor itself was too hot to work and managed to gather back its head after cooling for a longer while. I am certain i remounted the engine fine, as it did work fine for a while but again, i don't really know where to look at What do you guys think went wrong ? I would really appreciate any form of help Thanks in advance, One scared !Removed!. Quote Link to comment Share on other sites More sharing options...
