Hi, welcome to my first Post.
Back to business....i have a 2001 Bora TDi 115, beautiful car (pic soon) and have just today had the cam belt replaced. However, after picking the car up and cruising half mile to the motorway, i put my foot down only to hear a really loud Hissing (like the release of compressed air) the power was nowhere to be found and a puff of black smoke (more than usual) exited the exhaust pipe. I called the garage right away and the first word that came out of the mechanic's mouth was B*ll*cks, which prob means he has an idea of what it is. As a result, the car is back in tomorrow to be fixed.
now, i read the thread further down about a similar problem but there was no mention of a cam belt change.
I have been told that they might not have set the timing right, tensioned it right or even it may have slipped (toothed belt slipped??)

anyway, id really appreciate some quick replies so i know what im on about if the mechanic tries to fill me with bullsh*t. (pardon the lingo)

I'll keep you posted.
Cheers
