Additionally, unless included in "Zone A" above, Volkswagen is recalling certain model year 2004-2008 Audi A4, and 2005-2008 Audi A6 vehicles originally sold, or ever registered, in Arizona, Arkansas, Delaware, District of Columbia, Illinois, Indiana, Kansas, Kentucky, Maryland, Missouri, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Virginia, and West Virginia, or "Zone B."

This took place about a week ago. The car was parked in our driveway when the fire started. My husband had returned home just 15 minutes prior to the fire starting. I noticed there was smoke coming in our living room window. Then I looked at our security camas. And saw smoke pouring out from underneath the hood of my car. We tried to put the fire out with our two hose system set up and it wouldn't go out. So we knew it was electrical. We couldn't get close enough to open the hood so I couldn't pour baking soda on...

it. Two fire extinguishers later like 10 minutes the firefighters showed up and we're able to put it out. They confirmed that the arch came from the battery terminals /cables. Two of the fireman said they'd never seen anything like this before. Then the car tried to START ITSELF as my husband and the two fireman were standing right in front of the Audi. They had to cut the remaining battery cable that wasn't completely burned through before it stopped. My neighbor has a recording of the whole incident. The engine compartment is destroyed! The engine might be all right but we don't have the finances to do anything but clean up. Oh and for extra fun one of the fireman took an ax the the hood of the A4 cabriolet I have had for maybe a month. Now we have no car and no real means of being able to fix it.

PRNDS appeared in red on my dash and then started blinking. Went on line regarding this and read about a TCM switch or a lever switch malfunction.Have an appt with mechanic on 8/26/21. From what I have read we are looking at a cost prohibitive repair of several thousands of dollars. Does Audi have any responsibility? Apparently it is a common complaint with the A4 model. Felt loss of power when decelerating.

Gas pedal became stuck while driving on the freeway. I was able to pull to the shoulder by putting the vehicle in neutral and turning off the vehicle. Not sure exactly how this occurred, but it appeared that the pedal accelerated on it's own. I sent an email to audi to see if there were any incidences similar to this. The incident occurred on november 12, 2016.

Rear window of convertible soft top for 2004 audi a4 cabriolet. An old issue often suffered by audi cabriolets from 2003-2009. Claimed to be caused by the adhesive that audi uses. This can be caused by keeping the car outside instead of in a garage as prolonged exposure to sunlight causes the adhesive to give away and fail, causing the rear window to separate from the outer layer of the top and drop. While the window is still technically attached to the inner layer of the top, the window no longer protects...

against water. As a result rain can seep into the non water resistant inner layer of the top and then cause water damage to the rear seats. This is the case with my own car and with a large enough number of cabriolets that this should have been settled frankly, a good 10 years ago when the first cases were being noticed. I have as many others have, attempted to use a temporary fix and as a result, there is a clear industrial adhesive around the top and rear window to attempt to fix this, it fails with continued use.

Engine & cooling

Oil dipstick & support tube, made of plastic, cracks - brakes into pieces , both on the dipstick & tube that can easily go down the tube into the oil below. Looks like a poor engineering decision to use plastic that after years of heating to near engind tempatures then cooling has a high probability of cranckin and having pieces fall into the engine oil supply - possibally causing engind damage or faliure. Should be replaced every 5 years or with a metal structure that doesn't crack/break off into pieces. I would think from the youtube complaints on how to replace it I am not alone with this proiblem. Dealer part sales might confirm the problem.

Was driving on freeway for a few hours during which car was running fine, and car suddenly lost power just after I got off freeway and approached a mountain road incline. There was no warning light, or prior symptoms to engine failure, it just stopped. With help, I was able to get car out of the middle of the road and to safety. Tried to troubleshoot, used engine error code reader, and no fault codes found. Performed basics checked for potential fuel vapor lock due to altitude; checked oil, coolant and fuel levels-...

and all levels were ok. Battery was functioning - as radio, lights worked. Car has been consistently serviced and maintenance was current. Car was towed to nearest dealer, diagnosis by dealer fuel pump failure due to clogged fuel filter. My issue is that audi does not indicate service maintenance for fuel filter. There is not any maintenance recommendations or guidance in either the owner's manual or published list of recommended services to replace or check filer. There also were not any warning lights, fault codes or indications to watch for. I feel that it is negligent of the manufacturer to not indicate any service interval to change fuel filter in order to prevent fuel pump failure, and to ensure the safe operating conditions of the vehicle. The car lost power on a winding mountain road and put me at danger without warning. I am curious if this fuel pump incident could be associated with known fuel pump issues, nhtsa #pe08027. Key side notes, while I am the second registered owner, this car was purchased by my father who was the original owner, but for insurance and registration purposes the vehicle was transferred over to me, but I have all original records of the vehicle and can verify all maintenance services have been performed. *Js
