    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.

    That was my question too, if the car was running fine, why pour **** into its fuel tank!

    not really, just normal exhaust fumes really

    and hindsight is a wonderful thing lol

    its getting less often but when it does, the smoke amount is the same

    blast up and down the motor way till the tank is on fumes... then £10 of cheap fuel. the once that gone... tank it up with V power. if its still there... its not the red X

    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?

    yeh im open to the idea of uprated turbo and remapping. been quoted 1099 +vat by Audi just for the turbocharger, must be a cheaper option new

    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
