Aggressive clutch engagement A160 ACS
I have a 1999 A160 5 spd with ACS & it intermittently has very aggressive clutch engagement, generally in 1st & 2nd. Doesn't happen all the time & nothing specific induces it (although if you put the car in 1st, foot on the brake & give some throttle it will usually do it). Another forum member is experiencing similar issues in this tread.
The car has done 180,000km but the clutch doesn't slip, MB put it on there diagnostics and mentioned the vacuum hoses needed replacing, apparently the ACS is linked to throttle position, fuel load etc etc didn't seam like a real plausible reason to me.
Could it be the brushes on the electric clutch actuator? are there any sensors in the top of the gear box that can be checked, or could it part of the self adjusting clutch/pressure plate system.
