hi Julian

thanks for the info.

i would be very surprised if you have clutch problems with such low mileage and would consider this to be very pemature failure.

the dual mass on will not cause the clutch to slip this could be caused by faulty hydraulics , clutch or pressure plate.

ask yourself a question does the clutch feel like it is slipping ?

if not then it is probably a sensor fault, my advice would be to find a garage with suitable diagnostics to read for fault codes on the transmission module and delete the error codes and reread if the warning comes back.

the type of sensors on this model will correspond road speed to to tansmission/engine speed so i feel this is a sensor or programme error.

Hi Rob,


 


i have been told that dual mass flywheels are very unreliable and when they fail they cause grease to be placed onto the clutch plate which causes slipping.


 


are you aware of this.

hi.

the dualmass flywheel is a rubber and spring type setup and has no lubricant present if the clutch is slipping due to contamination from any fluid then it will be either engine oil from the rear main bearing seal or the concentric slave cylinder wich will leak brake fluid either of these leaking you would know.

regards rob
