Audi A6 3.0, THe engine seems to bog down when I step on the gas from an idol, only for a brief second then its fine.
However I did notice that while the engine idols if I take off the oil cap it seems to idol rough.
So I'm not sure if the 2 problems are together or what....but I need help!!!!

 

take off the oil cap it seems to idol rough. that's normal when did you do a service?? oil filter/ fuel filter/oil/ air filter

 

Is it the Quattro or the Front Trak. The CVT transmission seems to have a slight delay off the line from time to time. Although I have only driven one 2 or 3 times, I did notice the delay.

 

It's a Quatty!!! and I'm not to sure about the service as I just bought it a few days ago. I have an appointment at Audi tomorrow morn to do a once over to check everything out.

 

My 2004 A6 3.0 liter, has about gotten me T-boned on several occasions, when in an intersection waiting to turn left in front of traffic. I see my chance, turn and step on the accelerator -- and nothing! for about 2 seconds! -- while my brain is screaming "I'm going to die, here!"

Has anyone had the same experience? Is it a computer glitch in the accelerator-by-wire system that creates this long pause?

I also wonder if the computer mapping of the system might be out of whack, although I know less than nothing about such things.

Or, is there a way to adjust the system to eliminate those annoying pauses?

I have noticed the same thing on my 2000 A6 quatro 5spd tiptronic. I tend to think it might be something more to do with the transmission. The reason I think this is that when I use the tiptronic to manually take the transmission down to 1st gear I don’t seem to have the problem. If I leave it in full auto I definitely see the problem especially if I don’t actually stop but come close to a stop only. Its almost as if the transmission never really shifts down to 1st gear until you come to a complete stop. So when you take off from the stop it must shift down to first gear and then you get the correct amount of acceleration that you would expect.

I have been wondering if there is a way to reprogram the downshift points so I will do some searching on this site - I am sure its been covered somewhere.

I just purchased (weeks ago) a 2003 A6 quattro and have same problem. Mine seems only to occur during a left turn and only if I take my foot off the gas to let it coast around the corner, then re-apply the gas and it completely bogs down as though I'm running out of gas then after several seconds decides to pick up and drive again. Any chance this has to do with a wheel speed sensor being out of whack? I, of course, am not sure of the answer yet either.

 

Try changing the fuel filter, as they don't cost very much. A plugged fuel filter could cause the intermittent slow acceleration. Also, scan the car with VAG-COM. Bad ATF fluid could also make the transmission act up. Check all vacum lines for cracked hoses, etc.
