    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 **** 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

    any ideas?

    much appreciated

    Redex 'burns' with a white smoke mate. I used to use it to help clean the upper cylinder and valves on old Imp and A-series engined cars I had by pouring it in via the carb intake. The white smoke out of the exhaust was literally like a smoke screen.

    I used this on my old car. Poured directly into the cylinders. White smoke gallore.

    Suprised its still smoking heavily but i guess some could still be in the tank.

    i know somebody that used to inject it into the carb on his mini to use as a smoke screen at traffic lights, pointless in my opinion but there you go, so i supose this backs up what everybody has said already.

    is redex compatable with cats?
    I'd be warey of putting anything designed for a 1970's motor in a modern engine at the best of times.

    Why did you Redex it?.

    I'd never EVER put that stuff near any modern engine.

    I need a new turbo, which is good i finally got a diagnosis, the guy said my seals gone, no turbo rattle or lag tho so i was lucky he reckoned

    Plenty of spare turbos out there, about £300 on ebay for a low mileage one. I don't know anything about them mechanically, but could you have yours refurbished/repaired? Or even uprated?

    honestly mate just get it refurbished and save yourself a packet and get peace of mind and a guarantee!!, i had a td05 done by turbo technics, new bearings,seals, work on the housing, fully balanced etc all in was under £200 and they arranged collection and delivered it back to my door, why do people just assume they need a new turbo at the end of the day if it aint cracked or seriously damaged just get it refurbed mate
