you may have camshaft wear i have the same car same problem sa ai o zi buna!Hi,
I have a 2006 VW Caddy with 1.9TDI (BLS type) - 120000 miles. Very noise engine in the cam shaft area and a lot of black smoke when I push the acceleration pedal.
Could be a valve, cam shaft or turbine ?.
Any clue will be appreciated.
