Jason87 Posted March 2 Share Posted March 2 My clutch doesn’t slip but feels like it’s wearing thin when I pull away etc (doesn’t feel like it used to) and my torque/acceleration also feels off. Would a clutch that is wearing thin affect performance at all if it’s not slipping? Or is this more likely a separate engine issue? Mk2.5 tdci.

alexp999 Posted March 2 Share Posted March 2 If it’s not slipping it won’t affect performance. Are you sure it’s not slipping slightly? 1 Quote Link to comment Share on other sites More sharing options...

Well I’ve put it in 4th at about 25-30 and put foot down and it slowly picks up speed as normal, doesn’t appear to slip. I may just have a boost leak or some other issue like that then. Does forscan show you boost? Quote Link to comment Share on other sites More sharing options...

If I remember correctly what I used to know about engine output characteristics, that's probably not a good test, as at those low revs the power output is relatively low, compared with when the revs are at say 4500rpm. Try it at 4000 - 5000 rpm in 3rd and see if it slips. Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted March 3 Share Posted March 3 Don't forget this is a diesel...maximum torque is around 1800rpm. It's torque that slips clutches. 3 Quote Link to comment Share on other sites More sharing options...
alexp999 Posted March 3 Share Posted March 3 Top gear at 25-30 mph might be a better test. Quote Link to comment Share on other sites More sharing options...
Jason87 Posted March 4 Author Share Posted March 4 Still doesn’t appear to be slipping. If it was a boost leak, would forscan pick that up at all? Or only if it was really bad? Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted March 4 Share Posted March 4 You can use a live data graph to watch the MAP and MAF readings. If boost is leaking badly enough, you'll see less MAP increase than MAF. 1 Quote Link to comment Share on other sites More sharing options...
