Shuddering on acceleration

[Steve brown]

Hi guy, just picked up my 2007 sline 2.0 tdi and on the way back home decided to give it a bit of acceleration on a motorway, but as soon as I put my foot down, I reached 60 and car started shuddering and got worse by 70..rang the guy and he said it has never happened b4, (he would say it). Can anyone give me some advise as I want to know which direction to take?. Thanks

Hello Steve,

Many thanks for being in touch with the forum. 
We will need a good bit more information in order to give you meaningful advice:- 

Front of the car shuddering? Can you feel this shuddering through the driver seat? Is the shuddering speed associated or engine rev. associated. - i.e. does it shudder at a lower speed in a lower gear. Does the shuddering alter if you brake?

If this were mine, my first port of call would be to get all tyres (and wheels) thoroughly inspected by you local tyre retailers, and if found to be serviceable, to get them all rebalanced - on the basic logic of simple things first.

Personally, I would not be using this car until this check has been carried out. 
As a matter of interest, are the tyres of matching makes and tread wear on each axle? Make of tyres? 
Perhaps you could let us have some answers.

Kind regards,

Gareth.

Thanks for your swift response, I haven't had the chance to try anything as I only bought the car yesterday,and drove well on test drive, although there was no where I could open up, and where I bought it was 80 miles away. So had a good chance to get the feel, so as you can imagine, went into panic mode when this happened. I looked it up when I got back after phoning the trader, and found so many people with same problem on all audis, no one gave a difenfinate answer though. Seemed to be swaying towards inner cv, drive train.. Whatever that means? Dealer is playing dumb now, so be great to have some ammunition if it is a more serious problem, to get my money back. Shame as its a lovely car to drive until reaching 60 plus

Checked all tyres and they are all good and same make, but this would not stop the car going over I'd say about 3000 revs and 75 mile an hour, I did automatically think about balancing, but that wouldn't stop it going over a certain revs and speed or would it? Thanks steve

Hello Steve,

’Checked all tyres and they are all good...’

Does that mean you have removed each road wheel in turn and thoroughly examined each tyre and wheel? If you haven’t, then you unfortunately you haven’t checked them! 
I’m rather confused by the .’....3000 rpm and 75mph...’ bit, since this now suggests an engine revolution issue rather than a road speed issue - the two are totally different. 

‘Balancing...that wouldn’t stop it going over a certain rev. and speed’. 
Actual rev and speed restrictions are newly described symptoms, so that’s something rather different again. 
Kind regards,

Gareth.

Sorry I got the wrong jist of what you meant, no I didn't take the individual wheels off and check, just checked the makes and even treads on each tyre.. About 6mm.the trouble is I'm not that mechanically minded unfortunately lol. Which makes it more frustrating and being Easter weekend no where is open in order to get it checked out and haven't got too much time left if I am backing the car.. Really need to find out whether the dealer knew of this problem? When I rang him he said he personally knew the previous owner that had the car since new and he said that there wasn't anything wrong when he sold dealer the car. I haven't got back to him today as was hoping that someone can shed some light.. Like I said b4.. Car drove fine up to about 60 then shuddered and really struggling to go past 70. I held the stearing tighter just to see if it would pick up but seemed to be maxed out. I'm sorry for not being helpful, maybe someone could point me in direction of decent audi mechanic and not a rip off audi garage in kent

Many thanks Steve.

Unfortunately, this is going to appear critical, but you (due to your lack of knowledge with cars?) are not describing the symptoms very well, and if that description gets passed on to the selling garage in a similar way, then you are less likely to get the redress that you are probably entitled to. 
If this were mine, I would be getting this car inspected and road tested by a trusted local garage, and getting a report on its condition, and the diagnosed reasons for the faults you feel you have with the car. This report can then be sent (e-mailed) to the seller, so that they will have a clear/clearer understanding of the issues. 
OK it’s Easter, and you will be unable to get the car inspected until after the Easter break. This should be understandable, and acceptable to the seller. 
Today, you should send the seller an e-mail stating that in your opinion, the car has faults with its performance and believed roadworthiness which you are unable to diagnose, and that you are arranging to have the car inspected as soon as possible after the Easter break, and that you will report back to them as soon as possible after that. 

I cannot offer any advice regarding a suitable garage in Kent who may be able to inspect the car for you, but it should be possible for you to search out a suitable Audi independent in your area via. a Google search. 
‘....not a rip off Audi garage in Kent....’ ? 
Keep an open and unbiased mind Steve. Not all - in fact probably comparatively few - are rip off merchants! 
Hope some of this helps to form a plan of action with this, which should stand you in good stead. 
Kind regards,

Gareth.

Thanks Gareth for them words of wisdom, I shall do just that and have a look for an independent garage to check it out and get a report to forward on to the trader. Thanks again

It’s always good to hear/ bad to hear thing, when someone follows your advice, but I think it’s sound and logical in this case. 
Although I’m not the one in your situation, and I do sympathise, but experience shows that the situation always appears worse when it first occurs. Whatever the cause, it will be sortable, and the selling trader will (unfortunately for him) have to accept the responsibility for putting the wrongs to rights. Yes, you are going to have hassle/inconvenience, but it will be sorted one way or another in the coming weeks. 
Meanwhile, simply occupy yourself with on line searches for a good garage - it doesn’t have to be an Audi specialist, if  one becomes difficult to find, but has to be someone you can talk with and get sound advice on what is wrong. 
Perhaps you could keep us posted Steve, and of course, just let us know if you think we can offer any ongoing advice. 
Good luck and kind regards,

Gareth.
