Hi all, just wandering if you could help us out with a problem i've been having with my 1.6 '97 Audi A3..
Since about a month ago, whenever it has to sit in traffic for about 20 mins+, it chucks out a thick haze of blue smoke when I pull away; whether or on I put my foot down or just ease it. There's also quite a bit of black sludge coming out of the exhaust.
As long as the car is moving, it's fine, it's just when it has to sit for a while...
If somebody could tell me what might be causing this i'd appreciate it.
