Can anyone help me diagnose this : when accelerating from standing start revs climb without much acceleration, once I'm moving and up to 3rd gear acceleration feels almost normal.

It does almost feel like the clutch is partially engaged and it seems to be worse when it gets warm but wouldn't it be the same in every gear if it was the clutch ?

The turbo is fairly new, clutch and flywheel were done 40,000 ago and has juddered ever since they were replaced, garage said they would replace it under warranty but could never manage to reproduce the judder when they had my car, some days it judders all day, some days it seems to work normally.

Many thanks....

Sounds like clutch slip to me

Thanks for the reply
