hi all. I am just wondering if my turbo is on its way out. its only done 27.500 miles. Yesterday i was about to have a bit of fun with an audi S3 but when i set off it blew a big puff of blue smoke out now it has done this twice. I have just been out in it and it was great no smoke and felt really quick compared to yest. So was just wondering if anyone can shed light on my problem.
