Hi guys, new to the forum and just got my polo gt TDI. Completely standard. Noticed a few things. First is, when accelerating, upon coming off the accelerator, there's a deep groan from the right front of the engine. Have a feeling it may be a leeky turbo pipe? Also when in first gear at about 2500 revs, if I come off the throttle, then car slows quite quickly, as if the brakes are applied softly? Flywheel problem? Any help would be great. Cheers guys
