hi all this will test your brains , i have a 1998 110bhp sport tdi sallon passat which has done 150k miles ,when i bought it i was like there was no turbo power i have lifted the turbo vac plunger and it has not seized i check all the vacuum hoses all look good,the engine does not smoke at all even when i crawl her upto 80 m/hr .and sometime on small roads i can hear the little whistle of a turbo but i feels like the accelerator pedal is not connected to the engine.i can`t wait to feel what this 110 engine is like under throttle..iam sure iam not the only passat owner who had this problem
