You're right Simon, will do that tomorrow or when I get some more time on my hands and compare the two, I also wanted to check if one of the teeth on the sprockets is broken but obviously I can't turn them manually, although that would be really unlikely I guess
One more thing I noticed now on a cold start, which never happened before, is that the ticking appeared also each time when pressing the clutch pedal with the car staying still, and when letting go of the clutch pedal, it disappeared everytime. That's really confusing as the engine and the rear sprockets obviously are still spining regardless if the clutch is engaged or not
