Well, the dealer was told to replace the fuel injectors and clean out the carbon buildup. They didn't consider the carbon buildup to be much but did as Audi USA suggested. We've now had the car back three weeks and have put about 500 miles on it (city miles). The car now starts and runs fine. But I'll report back if anything changes.

how to shut off an audible warning signal by jpmrider

I have an issue that came up with my 02 Audi A4 1.8T
Similar to another poster here on this forum. I started having problems with my window on my driver's side not going all the way up.
Then the other day my door ajar indicator came on for no reason along with the dome lights and audible warning signal. The audible sound would last for a couple minutes and then go off but this door ajar problem seems to happen when I apply the brake, or sometimes turn on or off the radio or heater.
Also I can not lock my drivers side door by remote
Now until I get some money together I can get away with having the dome light out and using the key to lock my door but the audible warning is just too much. Also now when I put the head light on the audible won't just beep but it will stay on at a steady
sound until it shuts its self off and then maybe come back on later. Right now for the time being I need to disengage the audible system but I cannot find the fuse
that may be connected to it. Nor do I know if there is a fuse for this. Since I could not find it on the fuse arrangement diagram in the owner's manual. If any one might know of this feel free to give a reply

Your car's engine management system should compensate for the lower octane. All you'd notice was a drop in performance.

HEATER VENTS SOMETIMES BLOW COLD AIR by dma2

I have a 2006, Audi 4 2.0. My prior car was an A4, 2003, 3.0 and that car had a continual problem with the heating and electrical system. The heating vents would randomly blow cold and/or hot air ... one vent blowing hot air while the other blew cold air. Sometimes they would both blow cold, sometimes one would be warm and the other hot, with distinct temperature differences to the touch, and all the while the temperatures would be set the same on both sides. This problem would occur at random times. This went on for months without any repair success.
 
Now, my 2006 Audi is doing the same thing after two weeks of driving. I am dreading the thought of going through the same thing again.
 
When I took the 2003 to the dealer, I was always told it tested fine. After 5 repair attempts and being told "it was fine" I drove 28 miles to the dealer when it began blowing cold air so that they could see the problem first hand. They seemed surprised and still were unable to fix it. While this was going on, my brake light fuse kept blowing out and I had to have the light (fuse) replaced 4 times. I thought maybe the problems were related and were electrical? Someone familiar with Audi mechanicals said the problem sounded like the jay flap could be sticking and that he's heard a lot about this problem with Audis???? What is a jay flap?
  
Has anyone had this problem with their car? I just got back from a short trip with the 2006 Audi and I got a message that the brake light is out. HELP!!!!!!!!!!!!!!!!!!!! I am reliving Audi hell.

Re: Burns oil [Mr_Shiftright] by haagd

My 2007 A4 has been burning / consuming oil since it was new. The oil light has gone on 4 times. The PVC Valve has been repaired twice. I am now going through a second oil consumption study.
 
Is anyone aware of a consumer that has been successful using state lemon law rules to get out from owning an A4 with this quality problem. I am shocked that Audi and my dealership (in MN) is not standing behind this vehicle and making it right or replacing it.
 
Disappointed in Audi.

My 2005+ Audi A4 doesn't burn oil, but I was wondering if one can just use any major brand of synthetic oil that's advertised as for European cars. I had not known that some types were for European cars, but I noticed this wording on a few brands at the local Pep Boys. I know that Audi says the oil needs to meet a particular VW spec., but didn't see this mentioned on any oil stocked there.

Oils should meet a VW spec in the 504 or something like that range. It has changed over the years but if you look at a label on Mobil 1 0W-40 you'll see it. That oil is the most generally available that does meet the spec and I have been using it for years in my 2004 A4 1.8T. WalMart usually has it but AutoZone, Pep Boys etc... also typically stock it.

Thanks. With my A4 coming off warranty service soon I figure I'll get my oil changes outside the Audi dealership. The local Goodyear dealer said they don't do the synthetic oil changes, but they will do it for me if I supply them with the synthetic oil.

If your going that route be sure to either provide the large oil filter specified for that car or ensure they use the right one. There are smaller filters that will fit but that engine needs the large filter for capacity and cooling. Without the proper oil filter and the synthetic oil it a pretty sure bet that sludge will form in your engine.
