Hi I have a Audi a3 1.9tdi! It has 38 thou on clock. Problem is that when the clutch is held half way down it makes a vibration noise it sort of comes from the exhaust and the clutch feels a little vibratty but nothing major, anyone else had this problem???? Also a week a go I have out 10pond of petrol into the car then filled it with 60 worth of diesel and since then I have kept it filled with diesel and also has fuel filter changed. But when the engine is hot it takes about 10 seconds to start, but runs fine!! I've had it diagnosed but they can't find anything what does anybody think this could be, sensor or injector damage??? Thanks

 

I've recently bought a 2011 2.0TDI 138BHP Stop/Start with 22k on the clock. Generally very pleased with it, but worried about a faint vibration on the clutch pedal - only like a tickle under your foot (no noise at all) just as the pedal is released. Can simulate it by very lightly depressing pedal at tickover, irrespective of gear (or neutral). Dealer says "It's normal", but I work at an auction site and have the opportunity to drive lots of similar cars, and have only felt this on a couple of very high mileage motors. If it is a rough thrust bearing, I would want it replaced whilst still within 3 year warranty, but if dealer won't admit a fault, how can I do this?
I've done about 3000 miles in it now, and it doesn't seem to be getting any worse, so am I worrying about nothing?

 

I am a new owner of an A3 so im sorry this post won't help much but i do want to say if that one dealer you bought the car to didn't want to take fault why don't you just try another audi dealership. Make sure you don't tell them you went somewhere else first and then compare what they say. I have done that in the past with previous cars and sometimes it just takes that right service rep or mechanic to get the issue resolved or at least explained in a more detailed way that will make you happy. . Good luck!
