Careful with this one -- if you're seeing smoke under high load/revs on the highway, chances are it's black/grey smoke and is just due to the richness of the calibration.when did you buy your MS3 . last year ? what month ? I bought mine at the begining of March 2007 . it smokes on the highway usually when Im going about 65-70 and drop it into 4th to pass people . Just wanted to know if there was a way to tell if I have the newer turbo or the older one and if I need to get it replaced now . I have 24000 miles on her now .
Maybe you're already aware, but just to be sure, the smoke in question with these bad seals is a light colored smoke, white or blue-white, and I'm pretty certain it's most commonly seen at idle.
Also, is your exhaust modified? As has been mentioned, the turbo seal smoke is much more common with low restriction exhausts with fewer catalysts than stock.
