The sure fire way to tell what's going on is to log the clutch clamping pressures during each state. Then you will know for sure. I think someone on the t'internet did this with a Golf R, but I'm on a mobile phone at the mo so can't search easily. edit: Found it: VWVortex.com - Brake application = clutch depression Code: While stopped in neutral the pressure was 0 bar. While stopped in gear it was 2 bar. Upon releasing the brake (no throttle), it went up to 3 bar, then settled at 2.5 bar. During mild acceleration it peaked at 4 bar. During moderate acceleration it peaked at 6 bar. During heavy acceleration it peaked at 8 bar. During engine braking it dropped to 2.5 bar. Upon disengaging (~1000 rpm) it dropped back to 2 bar.
