Hi,i drive a 2003 A3 2.0 tdi...a few weeks ago my clutch pedal was staying down after motorway travelling and i had to turn off the engine and pump the pedal..my local garage told me this was the slave cylinder which he replaced along with the clutch (my car has done 100,000 miles)...when he gave it me back i then found that it was very hard to get into 1st and reverse gears and also the car would move if i had the clutch down but was in gear...my garage then told me this must be the master cylinder which he then replaced..i STILL have the same issues..he has just replaced the flywheel but this has made no difference,can anyone help please...Many thanks..Steve

 

Hello,
No solution from me in afraid, but just had my A3 TDi back from a clutch replacement. Same problem here, after a bit of gentle forcing manage to engage reverse gear enough to park it out of the way. With the clutch dipped selecting the forward gears are very clicky and generate a low humming noise. Have contacted a mobile mechanic to see what he thinks. Have you had any joy with yours??
