My 8p S3 is sick - Multiple cylinder Misfire and low oil pressure warning

Post by Mvuyiso »

Hey guys,

I don't post here much but right now I'm stressing beyond belief. So just a little background.. I did a full exhaust on my car 76mm throughout and added an exhaust cut out valve (cos rice). After this, I'd noticed that the idle on the car was never great with instances of it cutting out at times.

After a while, I put stage 2 software from a local tuner, and they'd assumed they done the hpfp internals on the file, and I drove it like that for a week. When the final file was ready the logs that were done at the time revealed that there was a little timing pull and the throttle continuously kept cutting off and coming back and cutting off again through the rev range.

Yesterday I finally did the internals on the pump, and while testing the car, it started misfiring quite badly and a quick vagcom scan at idle showed lambda to be around .7 .65... Which seemed that the file was overfueling, this was accompanied by pops and bangs which were never there before.

I then drive to my tuner, with the misfire, a total of about 20kms, and parked the car off hoping for the stock file back, which they said they can only get tomorrow.. as I drove home, the low oil pressure warning light came on, so I had to limp the car the rest of the way, since home was like a 2kms out.

Right now I have no idea how to proceed.. please help.

Thanks.

Thing is it gave a few errors before that, including esp error, power steering error etc, so I'm not sure if they were all actual errors

Actually there was a time it was scanned yesterday and multiple errors came up, including steering angle sensor, engine speed sensor etc etc.. that's why I don't know if the oil pressure warning is serious or what

Was the engine quiet as usual or some clattering evident?

Urgh seems I've double posted this. Engine is still relatively quiet. I'm guessing clattering means I should just bend over and lube myself up?
