Sorry to reply but new to site and cannot find out to use a new post. Just changed the cam belt on my Golf 1900 tdi 2003. and changed the oil. After 15 miles switched on cruise control and must be a co-incidence but car started to have a "whoosing noise" checked evrything and looked OK done a few miles and a big puff of smoke came out of the exhaust and car now runs fine but no guts in it. Oil is leeking from the intercooler pipe at bottom Is the turbo gone? Code shows 17964 charge pressure but re-set and shows no code? Any help grateful.
