First, are you certain that your dealer has performed the "standard maintenance" services? Audi dealers are know for "pencil whipping" the services to cut cost and labor while back billing Audi North America. Classic example is "Audi Air Filter Services" at 20k and 40k. Most Audi filter boxes are extremely difficult to access and as such the tech relys on the computer to tell if the flow through is negligible. I have seen several Audi come through with clogged air filter prescreens and elements that have not been serviced since the factory. Bottom line is poor air flow (even with computerized fuel injection) can cause loss of power and excessive carbon build up as a result of incomplete combustion. Have you seen the spark plugs? They would give you an almost instant indication of the combustion chamber condition. As for photos, I don't know why dealer would need photos, other than to cover their backside for warranty reimbursement from Audi North America, who I am sure would have a hard time believing a 15k miles auto could be carboned up. Any respect it will most likely involve extensive overhaul to ensure that the carbon is ALL CLEANED OUT.

I have a 98 Audi a4 quattro v6 no turbo. I had a misfire and it triggered the check engine (mil) light. How can I reset it without going to the dealer? Also, how do I reset the service warning indicator?      Thanks,      Dave Replies to this message: rowlandj (Nov 29, 2008 12:03 pm)

Replying to: dtkaczyk (Nov 28, 2008 4:03 pm) If you fixed the source of the mis-fire then the light will reset itself after a few run cycles. Typically around 3 trips.   On the other one sorry can't help with that.

Replying to: mercops (Nov 20, 2008 12:52 pm) I drive a toyota camry and mazda cx-7 and they both take all of 3 minutes to change out the air filter. How's that for so-called German engineering? Replies to this message: Mr_Shiftright (Dec 01, 2008 10:15 am)

Replying to: fonefixer (Dec 01, 2008 9:53 am) That's good but what really matters is how well it filters, not how easy it is to remove, right?   I'm just teasing you--I had a Brand X car that had 7 nuts to remove to get the air filter out, and three of those nuts were different sizes!!

Replying to: ilrndude (Nov 19, 2008 6:49 pm) I have a 2008 A4 / 3.2 Quattro with the exact same symptom, and the "check engine" came on while driving the car home from a 7500mi routine maintenance at a Bay Area dealership (Rector Auto). This was back in late July, and the car has been in and out of two dealerships since then. In fact, just took it back in yesterday to fix oil leaks resulting from the last dealership's repairs (they changed the cylinder heads, injectors, valve lifters, etc.). I still have the sluggish performance, and Audi USA "Customer Advocacy" has been playing hard ball and not willing to replace this car nor reimburse me for the lease payments. Please note my thread on another forum. There are several other folks who have experienced the same issue on their 2008 A4 or A6 with the 3.2l engine.   http://www.audiforums.com/forum/showthread.php?p=1005085#post1005085   I have an arbitration thru Better Business Bureau with Audi. It'd be good if we all could build a case and try to get our cars replaced. Replies to this message: ilrndude (Dec 15, 2008 7:59 pm)

Replying to: FTv2 (Dec 10, 2008 3:33 pm) 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.

#1876 of 2132 how to shut off an audible warning signal by jpmrider Dec 23, 2008 (11:03 pm)
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
