Hi, I am hearing a knocking noise that is very pronounced from the footwear when the car is cold when I release the clutch it goes away. As I can clearly hear inside the car I think it must be louder outside, it is a manual gearbox so I guess it might be the release bearing? The car has only done just over 2k, so a tad disappointed but I will book it in for them to have a look over the school half term. Anyone think I might cause more damage by driving around 'til then?
 
I'd suggest get Audi assist out. If they can't fix at your house or work then say you want a loan car. What they are supposed to do is get this arranged so you meat a loan car at your local dealer, and then it's the dealers problem. The loan car is provided by Audi assist not the dealer, so you don't have to book anything in advance. Then the dealer has to get it resolved quickly otherwise it causes them problems
 
The VAG group will use Europcar or Enterprise Rent-a-Car for the replacement, they will try and do car for car (a3 for a3), brand for brand, group for group. I wouldn't think twice about having audi assist(rac) out the last thing you want it is to cause more damage and end up being off the road for even longer.
 
I guess I should have put that the car isn't immobile and the noise goes away once warmed up. Obviously to hear it I have to turn the radio off but it doesn't sound as if something is about to break...
 
Do you think it's DMF related noise? Easily mistaken for thrust bearing noise.

The test is:

Start car
Lift and keep lifted, the EPB switch
Engage first gear, lift the clutch until it's at the biting point and the revs drop a little (still pulling EPB switch)
Can you feel an irregular vibration from the clutch pedal? Accompanied by an irregular groaning sound, that sounds like traditional thrust bearing noise.

I didn't know the 1.4 had a dmf but I haven't experienced what you have put...
 
I was using it to reply, not sure if it put my sig in, anyway not like you to not have attention to detail :p
Having said that some petrol engines do have a dmf and you got me thinking that perhaps the cod had it for two cylinder mode....
 
Anyway, the car is in to have this looked at and a noisy sticky passengers door mirror. They've already rang back to say a replacement door mirror is on order and they'll keep the car so they can perform a cold start for the 'clutch' noise. They given me a brand new A4 black edition s-line 2.0l diesel saloon to wander about it, ****** dinosaur....
 
Got the car back, the mirror is now fine and the washers have been adjusted. Unfortunately they couldn't replicate the noise from the clutch area because the ambient temperatures have been too. At least now the issue is logged and, when the car is in for its service in January 2015, we will be experiencing normal winter weather. I must say, in going back to my car from the oil burning a4, was most enjoyable. Compared to the a4 my a3 is so much more refined, enjoyable to drive and dynamic and the 1.4 petrol engine is such a pleasure to drive compared to the gruff diesel.
 
The car is going back in as, to me, the noise has increased and doing it more often. This time they're giving me an A1 with s-tronic, will that be the same as on the a3 with flappy paddles? I should have it for a few days so it'll give me the the opportunity to thoroughly try it, instead of the few miles I tried the last one for, and I will try to keep an open mind.
 
Not all S-tronics come with flappy paddles, I think flappy paddles are an option in most cases.
 
OK thanks, I know that not all s-tronic's had paddles, that's why I asked. I guess I will find out tomorrow...
 
OK the car is at the dealership and I managed to demonstrate the noise to a technician, however he did suggest it might be normal, not convinced by that. I suggested they put the car up on ramp so they can start the engine with someone underneath, if it makes the noise I am hearing, and they actually do hear it, then they should have something to work on.
The loaner turned out to be an A3 but it is all my nightmare's rolled into one; it's brown, it's a three door, it's a 1.6 diesel, it has s-tronic and, worst of all, it has this archaic system of using a key to start the engine, jeez...
Anyway, my initial impressions were, deep breath, of the diesel mated to the s-tronic were mixed, some was good, some not so good. It still seems that they haven't improved auto mode much over the cars I was was driving in the '80's. More throttle has to be applied to pull away than anything I am used to with my car and the kickdown still seems to be lethargic. However I've yet to try it out with the paddles so I expect an improvement. Oh and it creeps forward too much when no throttle is applied, something I guess I notice more after having driven manual boxes for so long. I could write more about the car, again it's mixed, but to cut a long story short it isn't anything like as refined as my 1.4 engine.
 
Has a phone call from Audi, as the weather was much colder this morning they've detected the noise so now they're going to strip out the gearbox and clutch to investigate. I wonder if I should have stayed with my more reliable Ford's? No, these things happen but as the car is less than a year old, done only 4.5k, and the noise has been present for some time, I am rather surprised at this...
 
Finally getting my car back tomorrow morning after having a new dual mass flywheel fitted, yes petrol engines have them as well. I have agreed that I will then test it for noise, as I am probably best placed to do that. It will be so nice to get back to my car again.

Did I not sort of agree with you in post #10, but I wasn't sure if the 1.4 engine had one and neither were you, I know that some modern petrol engines with high compression have a DMF, my last Ford with a 1.6 Ecoboost engine had one. Anyway they have just rung back to say they do want to keep my car until next friday now to throroughly make sure. That means I have to put up with the courtesy car with the ****** awful ignition key and it's 1.6 diesel for a bit longer.
 
Of course, replacing the DMF might not have solved the problem anyway !
 
Exactly, seeing as they had a problem replicating the noise anyway. One of the reasons I wanted the car back is that I would hear it if it was still there which at first they agreed to then the technician said he wanted to keep the car for another week. I am so missing my car but at least this will definitely mean I will not exceed 5k miles this year.
 
Picking it up tomorrow morning, they say they haven't heard any noise since the new dmf has been fitted. They did state that the centre of the flywheel appeared to be worn which is puzzling as the noise first appeared at about 3k and one thing I never do is abuse the clutch. Still we will see if it has been rectified but I will be glad to get rid of the A3 loaner and back into my own car.
 
I have the car, however when I collected it there was vibration detectable through the steering wheel at around 80mpg that got worse when I deaccelorated so I got one of the technician's to sit by my whilst I scared the crap out of him. We agreed that perhaps everything needs bedding in and I'd give run the car over the Christmas period and see how it goes. Got a tasty 50mpg+ from the car on the run back from Eastbourne, far better than the 34mpg from the loan car....
 
Should have read 80mph not mpg damm predictive text. Trouble is most of my driving doesn't allow me much over 40mph so I don't get much of an opportunity to reach high speeds. But fortunately we've a trip over Xmas that might allow for some faster speeds.
 
OK, after a round trip of over 330 miles and several cold starts I can say that the car has behaved impeccably without any vibrations...
 
New DMF cured it then !

I was in (yet another *) courtesy car the other day, it was a 1.4 with DSG, 3000 miles on the clock.

Everytime you took your foot off the brake, and the DSG took up the clutch to creep, there was this juddering from the drivetrain.

It was horrible, I'm guessing either DMF or the clutches in the DSG have problems - but shocking at 3000 miles !!



*mine was in to have a brand new camshaft adjuster assembly on the S3, current unit had failed in 7500 miles
 
Mine is a manual, but a new DMF and a complete clutch assembly, can't work out how the centre plate looked worn after less than 5k though, I treat my cars carefully, well most of the time ;) Reliability isn't proving to be one of the strong points...
