    Hi, I just purchased a 2005 1/2 Audi A4 2.0T Quattro, & I have the same exact problem. I bought it to the dealer 2x already & they said there's nothing wrong with it.They said they put it on the computer & the codes were right. The car vibrates so bad ,that I have to put it in neutral at every stop. is there any way to stop this I'm ready to get rid of this car, the vibration is way too uncomfortable. There has to be a something wrong with this car! Is there any way this can be fixed?

    I have the same problem. Every time I tell the service tech about the vibration, he tells me it is "in spec"! How can a heavy vibration like that be "in spec"???

Well, as long as the engine lite is not flashing, it is considered safe to drive temporarily. i suspect you could have a misfire issue. need to read codes in vehicle computer. ill try to help best i can. are you mechanically inclined? may want to go to autozone for free code scan and get code # for me. could be spark plugs, coils. other variables involved as well

My car won't accelerate seems there is no pressure its Audi A4 2006

Most of the time when an epc light comes on and you have no throttle response it's best to connect it to a bag-com but if you don't have one have the computer scanned for a check engine code remember just because there's no check engine light on doesn't mean the ecu doesn't have on in memory.. So if you do have a code like p1639 then you have a bad accelerator peddle

Audi A4 Fueling

I learned recently from a customer that on the Audi A4 1.8T (and possibly other models of Audi) - when fueling, make sure the fuel cap is turned (tightened) at least 4-5 times to ensure the seal is good. Otherwise, the check engine light will come on and the pressure (lack thereof) in the tank will affect the performance of the engine.

This may be true as well for other makes an models of other brand vehicles.

Hi You may have to replace the system pressure cap. Also check to see if the system is under pressure soon after starting the engine if it is it could be Head Gasket, my money is on the anti-free reacting with the rad cap (for your sake), have a look at the over flow hose to see if the end is whet after a short drive. Let me know how you get on and any more info that would help me this end. Regards David

have you checked your calipers? They may be sticking putting lots of strain onto the drive shaft causing it to vibrate.

With all the recent snow and grit on the roads you may have some caught in the mechanism meaning it cant release.

Just a small thought to start to determine the problem.

These cars are very complex and it's not easy to diagnose. You should take it to a qualified technician with the proper electronic disagonstic tools to verify the problem. Start off with a full scan. It may be a simple as a software upgrade or as complex as the tranny needing repair. I wouldn't drive the car hard and get this resolved asap.

I have a 2006 Audi A4. Weird noise.

Could be a broken motor mount, so that one of the pulleys is scraping a shroud or some other fixed item.
Examine the area around the pulleys and see if there is bare metal below one of them.
If so, have the motor mounts checked.

2003 Audi A4 1.8T Check Engine light on

The CEL means there is a Diagnostic Fault Code stored in the Engine Control Unit. There are 1000's of DTC's, so you will need to have it read by a Code Reader. Auto Parts stores like Auto Zone, Pep Boys, perhaps even Advanced Auto often will read the code for you; but by law they cannot clear the codes. Many codes do not cause drivability problems, severe ones will trigger the ECU to run in a Limp Mode, which would require repair work before any trip longer than a few miles. Hope this is helpful.
