    Hi guys Ive had a vibration in my car at 70 plus mph coming more from the front , Under warranty Audi replaced the prop shaft . dunno why they said there was a fault with it ?

    Also Audi said the CV joint on the left was knackered so Ive had it repaired , and Audi said it isn't the wheel bearing's so I'm kinda puzzled , Me and a friend took it out tonight on the motorway and the vibration starts at 70 mph and just stays vibrating as i get faster , we've ruled out warped discs as steering wheel is fine under braking , wheels have been balanced CV joint repaired also when i take it out of gear it still vibrates its not as bad when accelerating but gets slightly worse when cruising , I'm baffled the only thing i can think of is a slightly bent drive shaft would this cause it and is this covered under warranty ??

    Also the work was carried out under warrenttee but since they failed to fix the vibration and my car is now out of warrentee should they by right still fix the car under warrenttee ?? Hope you can help guy's thanks's

    I had the same issue, was bad when cruising at 50mph+ when accelerating the vibration increased with the revs. I booked mine into Audi and they replaced the wheel bearing. Problem solved :) Have you checked your wheels are balanced ok??

    Cheers Davie

    Yeah ive had the wheels balanced and checked and audi said the first things they checked was the bearing's

    Im just gutted i had a couple coming to see the car this week and thought the cv joint would sort it , The car drive's fine everything is spot on apart from this effing vibration .

    Dave Was it driving round corners the noise got worse or just over 50 going straight as i seem to get it , Also was it repaired under warrennty or not if not how much if you dont mind me asking

    great let us know mate thanks , Doesnt mean its the same though but we will see , Mines more of a vibration you can feel it under your feet ...

    Im taking out an audi engineer tommorrow for a spin to see if he can spot what it is . I just hope its not to expensive im hoping it will be done under warrentty as it was in audi under warrentety for this problem but they hav'nt fixed it , So im hoping for a goodwill gesture as by right's it should of been fixed under warrentty

    Was repaired under warranty and yes the vibration would increase when cornering.

    Well i took an audi guy today he was trying to say it's a different problem and repairing the prop shaft sorted the original vibration which he is blatently lying , I dont know what to do now im trying another set of wheel's on the car tommorrow do definatly make sure its not the wheel..

    If it is drive shaft then i think its gona be an expensive job if its wheel bearing's il have to see , But if the to**ers would of picked this up under warrentty it wouldnt be costing me nothing im kinda peed off , good result though lads nice one i just hope mine is a wheel bearing to

    could be a dodgy tyre, balancing or a bearing

    should be could be something as simple as a balance weight come off, look for evidence of that, if its that then its find but i need not tell you to take it canny, like you should be doing anyway roads are ***** just now!

    it would be easier to diagnose if i could drive the car obv, check all your pressure and tyres for bulges

    Can you feel the shaking through the seat or through the steering wheel?

    I had a similar problem, was an inner CV joint. Faster I went/harder I accelerated the worse it was, might be worth a look...

    I know it's nearly a 5 year old post but did you guy manage to solve this problem?

    I have the same thing just purchased my s3 few weeks ago and has the exact same problem as Binnsy, a vibration around footwell both passenger and drivers side. Brrr ..... Brrr ...... Brrr ..... Consistently like that at around 70mph+ slowing down and speeding up with the speed.

    Mine was the prop shaft nuts/damper unit thing. I think it comes out of the transfer box. I don't know what it's called. I'm no mechanic...

    They may have replaced prop and not the bit I'm trying to describe.

    Sorry for being vague and non specific on what the part may be.

    After obvious wheel bearing / prop shaft issues...i'd be looking at out of round / oval wheels or worn tyres (not as in low tread patterns but in cracks in sidewalls & general aging / degrading)

    I've had an alloy wheel on mine crack....an original 17" 5 spoke sline Ronal. Heard lots of stories of wheels on high end golfs going oval & buzzing. Balancing will stop side to side vibration but don't think it will sort oval wheels.

    And is there any way to check if it's the wheels themselves without changing alloys?

    The only tyres I haven't replaced are the rears as there's plenty of tread left on them.
    I've had a 4 wheel alignment and 2 new tyres recently on the front. Been to a private garage and audi, had 3 technicians going out in my car, nobody can locate the problem.
    Audi said it's definitely not the wheel bearings.

    I was advised to get a fast road wheel balancing as they balance the wheels up to say 80mph rather than maybe 12.

    I'm thinking about getting the wheels rebalanced and then when the 2 rears wear low I'll replace them aswell.

    Swap wheels front to back to see if it changes to eliminate wheels.

    I'm having the same problem, I'm going to get both wheels balanced again tomorrow and will report back

    I've had the problem for a few years and only getting around to seeing what the problem is. I should got it sorted when the car was under warranty but put it down to wheel balancing but I don't think it is.

    Sounds like a common fault?

    I've also got this issue right now. Had 4 new tyres onto the wheels and supposedly balanced & aligned. I stuck it back in to the garage today to get the wheels balanced again (and stupidly missed their calls to come pick it up again) but I'll have it back on monday and update if it fixed my issues.

    Weird how common it is with no solution to the problem..

    Let us know how you both get on..

    When I went to audi the head technician said leave it until it progressively gets worse (if it does) to be able to identify the problem more easily.. Great help!

    Quick update. Got front wheels balanced today at kwikfit (jolly nice bunch and quick service if I may say so) and took the car for an immediate drive and noticed a slight improvement but not cured so thought I would leave until my next scheduled service for investigation however approx and hour later after driving and coming to a standstill I noticed an odd pulsating whirring type noise coming from the front drivers side axle area. At first I thought it was something rubbing, then thought some gearbox teeth were grinding but it appears to be neither.

    Points to note:

    It only happens at low speeds (0 to 40) even if I lift and coast
    It continues to happens if car is put in neutral and coasting
    It continues to happen if car is put into neutral, engine switched off and coasting
    Appears to be worse when cornering left, less noticeable when cornering right
    Stops grinding / whirring when brakes are applied
    When traveling at a snails pace the noise sounds like ball bearings stacking upon each other cyclically / pulsating during rotation


    To me it sounds like a Wheel bearing but will not know until I speak to Audi tomorrow or take to them for further inspection.

    Thoughts?

    Definitely a wheel bearing. Everything you have tested and described points exactly that.

    Jack the car up and test each for wheel bearings for play. Should be fairly noticeable

    Keep us all updated please mate.

    Is yours a vibration similar to mine where it's on... Off... On... Off..
    Or is yours a constant vibration whilst the wheels are rotating at speed?

    You say that as so many people have said to me but after taking it to a private garage and audi themselves, both insisted the wheel bearings are fine.

    An audi technician did suggest to spin the drive shaft 180degrees as that can sometimes solve some vibration issues but again couldn't guarantee it would solve the issue.

    Mines a constant vibration but only between 75 and 85 mph. Typical, just the speeds I like to cruise at!!! Used to disappear over 85 but haven't attempted this since today's newly found issue.

    I had the exact same on my S3 for ages. I got Audi to have a look and my wheels were buckled. I got a good refurb on them and it improved things but it was never fully resolved.

    Yes of course, they do anything on VAG cars, just phone them.

    Okay so it seems my vibration has gone now ... i replaced a rear tyre due to a slow puncture and maybe the garage did an all around check on all tyres or something but now i no longer experience this... this all does seem to be wheel balancing / bearing issue though...

    Took the car to Audi yesterday. On the drive down to them the noise was getting gradually worse which developed into a knocking / thudding noise with mild feedback felt through the steering wheel.

    A technician took it for a road test but we're puzzled to what the noise is. They observed all of what I mentioned above (more noticeable on left lock than right, stops when braking , still there when coasting etc.....) so decided to put it up not the ramp to take a closer look. 30 mins later technician returns and is still unable to diagnose and said it will needs further investigation but it seems to be either a CV joint or wheel bearing, according to them.

    I have left the car with them as they advised against driving the car in the current state.

    As always, I will keep you all posted.
