zsharmask Posted May 16, 2011 Report Share Posted May 16, 2011 Hi, Help please! I have a 2.0 TDI 2005 A6 with 101000 miles on the clock. The biting point went from midway to the very top of the pedal travel. My local Audi specialist replaced the clutch Kit (plate, bearing and pressure plate I assume) AND dual mass flywheel due to judder. The car was fine for a few days but the biting point went to the top again and there was a little vibration. The garage then replaced the slave cylinder took the card for a test drive and as it didn’t resolve the problem he booked the car back in to have the clutch and DMF replaced under guarantee. This was completed last Friday. I started the car this morning, pressed the clutch pedal engaged 1st lifted my foot but the pedal failed to return to the top and the car started to move, I had disengaged the brake by now, the only way I could stop was to keep my foot on the brake and stalled the car, forgot about turning ignition off as I was fast approaching my garden wall! I was able to lift the pedal back by hand and it has been fine since. What could the problem please ? Cheers Link to comment Share on other sites More sharing options...
cruiser647 Posted May 16, 2011 Report Share Posted May 16, 2011 Sounds like a leak somewhere? Check your hydraulic fluid levels constantly. Link to comment Share on other sites More sharing options...
zsharmask Posted May 16, 2011 Author Report Share Posted May 16, 2011 Sounds like a leak somewhere? Check your hydraulic fluid levels constantly. Many thanks Cruiser for your assistance. The garage in question are looking into the problem for me and will call me tomorrow. They have already changed the Slave; without any additional coast to me, and suggested might need to look at the master cylinder and a ‘small hose’, related to fluids like you suggested.

cruiser647 Posted May 17, 2011 Report Share Posted May 17, 2011 A small leak will mean you have an air bubble in the system. Air compresses easily! Good luck! Link to comment Share on other sites More sharing options...
zsharmask Posted May 23, 2011 Author Report Share Posted May 23, 2011 As suggested there was a leak. The mechanic replaced a hose connected to the slave and bleed the system. All seemed fine until I took It for a 40 mile drive yesterday evening. I was on the motorway traveling about 70mph when the traffic started to slow down. As I went to change to lower gear I noticed that I had about two thirds of clutch pedal play. The pedal only engaged gear (clutch)in the lower third of the pedal travel. The rest was just free play, although the pedal no longer drops to the bottom. Back to the garage this morning then… Link to comment Share on other sites More sharing options...
