Some insight please

Well I hate to be a pain in the ass, but I’ve searched and found nothing that helped. Over the past months I’ve had this problem that has not stopped and scares me. So a few months back i took my car to my local Audi dealership and had them go through it (not a reputable dealership but only place for miles). They came to their wild conclusion that the motor mounts were shot and I needed to do $3500 worth of service.
Being very doubtful that this was the problem I contacted the Audi dealership (Audi of Raleigh) where I had purchased the car not long ago. I began to go a little crazy on them and went on to ask them how they could sell me car with broken mounts etc… They told me that the next time i had the car down their way to bring it in free of charge, and they would look over the car to see if they were infact broken. Well over the past weekend I went down and took the car in and gave them the whole story of my fiasco with my local dealership. So I left the car and waited for the dreaded phone call, later that evening the service manager called me and told me that nothing was wrong with my motor mounts or anything for than manner. I spoke to 2 different techs that drove it, and they said that nothing was wrong that they could see or feel.
So after this whole deal of bulshit I am still stuck with something that bugs me and no fix in sight. The problem that is occuring that started this all is that when 1st gear feels like its not all there like when I first got the car. Then in second gear under WOT around 3600rpms the shifter begins to start dancing around, then shifting to 3rd under WOT the shifter will start dancing again. Its as if something is loose, it does it some what in 4th but not as bad. Also shifting between 1st-2nd and 2nd-3rd if not dont in a certain mannor it bucks around so to say like the drivetrain is loose. But if I’m on the throttle some (not Wot) and I shift there isnt an issue, I am clueless as to what is going on??

If anyone has any ideas or has had a similar case and could help me with some advice it would be greatly appreciated, sorry to be a pain in the ass.
Thanks guys,
Nick

Did you see them physically inspect the motor mounts or just have techs drive it?

Did they scan for codes? - the reason I ask is that the B6 motor mounts throw a code, but don’t trigger a CEL. This would indicate a leaking/failing mount. (At least, one of mine is atm, but hasn’t triggered the CEL, so I’m not sure that it doesn’t entirely.)

How many miles are on your car? The snub mount could also be bad which may cause some issue, but not likely to the magnitude you describe.

Did they inspect any other mounts like the trans mount?

Did you ask them to inspect the drivetrain?

The other thing I would think of, is possibly bad synchros. Hopefully that’s not the case.

They Physically inspected the whole drivetrain and all the mounts from bumper to bumper. They had the car on the scanner and threw no codes but a faulty brake switch which is nothing. they said that the mounts arent leaking and look fine but who knows, on the ride back home from Raleigh I just hit 92k. I’m thinking possibly it could be the snub mount but I’m kinda taking their word on inspcecting the whole thing. And i pray to god that it isnt the synchros.

#4

@92k you might need new motor mounts. But it isn’t a $3500 bill. Get Stern street density mounts about $260 I believe. Its DIYable or you can find a reputable shop that doesn’t believe in raping its customers.

Your snub should be replaced as well. Mine wasn’t shot but I was amazed at the difference a $40 Apikol mount made in taking the slop out of the drive train.

#5

I had an appoitment with Apex Tuning to do 034 zero gap bracket , Alpikol snub, Stern street mounts, and 034 trans mount. But I called it off after they told me nothing was wrong, and i know that it isnt going to cost $3500 thats just what audi wanted to rape me for. Apex Tuning told me that for $850 ( labor and parts) they would have done it.

#6

Wouldn’t hurt to give new motor mounts and a new snub a shot.

You could also check out and make sure everything is completely tightened up with your shifter, every part of it.

#7

Yea I’m thinking about going that route, I dont think its the shifter because the way this thing moves is violent.

#8

Definitley sounds like your flywheel is on its way out. The car goes into a limp mode when it detects a vibration like that. It’s a notorious issue on the b6 unfortunately. If you leave it too long the flywheel can go book and do a hell of a lot of damage so get this sorted quick

However, at that milage, you are definitely due for some new motor mounts. Although I doubt that’s causing your issue. When the motor mounts go bad they almost always lose their fluid thus triggering a fault code. that’s not to say they aren’t worn though.

#9

Sounds like a good excuse to get a lightweight flywheel :smiley: you won’t regret it.

#10

You know what now that I read it and take the known facts out… It sounds almost identical to when my flywheel did the same thing.

It took me 3 trips to the dealer and each time I waited for it to start happening, then called my service advisor and had him or a tech meet me outside practically immediately to drive the car.

#11

Hmmm you guys really think its the flywheel? I’m not saying that I disagree I’m open to all possible ideas , but if it was the flywheel wouldnt I have a constant vibration through the whole rev range? And for my car to go into limp wouldnt I have to have a CEL that would throw a code to put the car into limp? I’ve looked over the entire service history of the car and found that at 66k the flywheel and clutch were both replace by Audi. Could it be that the flywheel already took a shit on it again so soon? And I deffinitly agree that I have to replace at the mounts in the car thats going to be done this spring regardless. Over on the zine Amsterdamned told me he had the same exact thing going on thats happening to me (http://www.audizine.com/forum/showth...t-a-difference )
I dont know I’m just so frustrated that I cant figure this out, I appreciate all your guys help.

#12

If they replaced it with the same B6 flywheel, it could have returned that quickly. It was a common issue with the flywheel they used.

When I had the issue it didn’t happen in the entire rev range. It also didn’t happen everytime I drove it either.

#13

it reminds me of the flywheel problems but I don’t have enough experience with it.

the B6 flywheel sucked. Some of them would seperate and then you’d run the risk of damaging the bellhousing. An expensive guess though, to replace a clutch/flywheel just to see if it solves the problem.

#14

A local guy on AZ had the same issue with the same symptoms so I think it’s the flywheel again. There is really no limit to how early it can fail. If it was beat on then it’s life will be dramatically shortened.

Could also be the crank pulley. A friend of mine had a similar issue on his 1.8t A4. The rubber in the crank pulley started to disintegrate.

Either way this is something you need to fix as soon as possible. Vibrations at the crank can be very bad

Thanks guys I really appreciate all your help and insights. A buddy of mine has been working on Audi’s and VW’s for years I’m gonna bring it over to him and let him go through things. I’m definitely going to do all the mount upgrades and while I’m at it I will probably go for the JHM goodies, just gonna have to scrape up some cash.
