Hi Rainer, ...
Don't think I'm crazy, but sometimes the clutch engages very abruptly... not me, but the clutch itself. Then there's a muffled 'thump!'
Okay,... this might not belong in this thread,.... but you gave me some advice because my TDI is making a clacking noise,........ I went to another workshop today,........ their assessment was: It's not normal, but it can't be properly localized,........ so we'll just wait and see if it gets worse! Great answer
