Hey guys i was wondering if you could possibly help
I bought a 2000 S3 4 weeks ago today, and up till last Monday it was working fine, had the time of my life driving it round and no obvious problems bar a squeaking brake. So last Monday i poured some red-ex in to a full tank, and since that day its pissing out white smoke from the exhaust but only when its at 90oC.
it takes bout 5 mins to get to 90 from cold, and the smoke doesnt always piss out, however round town in 2nd-5th gear, itll sit there pissing out smoke on gear changes, and can do when im idling at lights and junctions. however when i get a good stretch of open road, it rarely billows out.
now ive searched for white smoke on here, and seen HG Failures/Turbo Failures but ive checked the oil cap regularly and theres no crap at all on it, the coolant tank is still nearly full and the dip stick shows no sign of gunk. the turbo is still having a massive boost and the dump valve/wastegate is still whirring away.
Im on my third filling since i put red-ex in, (first about 50l, second 20l, third 15l) but im really of whats going on
