The first signs of anything wrong with my clutch a few months ago (car was at 173K) was a noise audible when depressing the clutch when reversing up my drive , the rest of the time it was OK.
I decided to get a garage do the job and they whipped everything out , decreed that the DMF had gone and that it had also damaged the main crank oil seal.
So, one oil seal and complete LUK clutch kit (inc DMF) later the car was back with me and smoother than ever, the factory installed assembly was also LUK.
I reckon the DMF had been failing slowly for years , when I bought the car (at just over 110K miles) it really didn’t like 3rd gear at 1400 rpm, there’d be a nasty judder and I always had to change a gear to avoid it .
With new clutch & DMF it’s totally gone .
