My car is doing the same thing.. could you describe the process for removing the solenoids?

1999 A8 Q 4.2 and just passed 150,000 miles. I have the trans fluid changed every 25,000 miles and just put on my 3rd belt. I have had some quirks with the ABS sensors, which I fixed by removing and cleaning with brake cleaner. I also own an A4 2.8Q just passing 200,000 miles. I don't disagree with problems with the transmission; however, you can't expect to drive the crap out of the car without doing some PM. If you can't do the recommended services, then you should probably stick with a Honda or a Chevy. I make no excuse for the faults of the car, but anyone who purchases one of these wonderful machines, should understand you cannot drive this car cheaply.

The trans problem is a blown "F" seal and will require a rebuild. The cluster will also require replacement, about $1,500. There is no fix unfortunately.

Just purchased an 00 A6 4.2 with 80,200 miles on it. A week after purchase, the transmission started having issues clunking when shifting down into 2 and 1. Also upshift to 3 and 4 is rough. Changed the fluid and still the same.

Bought a warranty for the car for 1000.00.

Changing the oil the other day, I found the pan gasket leaking, so I dropped the pan only to find 1/2 of a valve in the bottom of the pan and the keeper for the valve spring. Quoted 3500 to replace transmission and 4800 to replace driver side cylinder head.

Now in the process of returning the car to the dealer I bought it from. I love the car, but if I would have known the car needed 8000 in repairs, I never would have bought it. =(

I have a 1997 Audi A8 4.2. I was having problems with the tranny, so we bought the tranny service kit from a local euro parts dealer, and let me tell you, what a job we had. I have changed screens in a tranny before, and no where near as much of a headache, wow. But needless to say, I had all of the problems above, but it cost at most 100 dollars to fix. Garages see the Audi and think money off the top.

I have an Audi A8 1999 2.8 with tranny problems. It seems to rev up when it decides to change gear. It is OK if you are going slow with little throttle, but if you open it up, it revs up in middle of changing, then clinks quite badly into gear. Also it has lost a lot of power and seems to be missing slightly.. I have changed the fluid and filter in the tranny.. could this problem possibly be the throttle position sensor? It comes up with no fault codes however on a snap on diag machine, or could it be the solenoids need cleaning out, OR could it be the transmission ECU unit knackered??

Any help welcomed. Thanks for reading.

I have a 1997 A8 that needs a TCM I have been told. The car only goes into 4th gear. When I start the car, everything is fine, including reverse, but when I go to put it into gear, it won't shift. It sits there like it's in neutral until I rev the car up to 1,200 RPM, then it clunks into 4th gear.

I read in the manual this is in safe mode and I need to change the TCM. If someone could help me, that would save my life! I am a full time college student that needs help bad!

Thanks for all your time! E mail me with any advice/ solutions!

I have 1999 A8 Quattro, and recently changed the battery, and now the CD player is saying safe. I do not have the owner's manual. Can anyone with the same car can tell me the 4 digit code to reset the CD player, because it keep saying safe and does not play. Needed a 4 digit code. I called the Audi dealership, they want to charge me $400 just to give me the code. That's crazy. Please, any one help me, please.

Have you tried simple codes as e.g. 0000 or 1234. If I'm remembering correctly, it's a simple code of this sort, but unfortunately my car is in for a repair, along with the service documents etc, so I can't check until late next week.

I bought a 2002 Audi S8 with 150000. Drove the car 10000 miles. I asked many shops and dealers; all said to leave the tranny oil alone because it might do more damage to change the oil than to leave it. Why is there no solid answer? Now my tranny slips and makes a whining noise.

Hi, I have a 2002 Audi A8 Quattro, and one fine day it decides that it wants to rev up to 2500 to 3000 rpm or so to shift to first. It also jerks every time it shifts into 1st, 2nd or third. We replaced the oil and the filter recently, but still the problem persists. Anyone have any idea what it may be?

Had a hard shifting problem with my Audi A8 and the German Car Depot in Hollywood Fl checked it out and fixed it for $400. The dealership said I needed a transmission.

Thanks to the gang at German Car Depot.

I have an Audi S6 2002. Car drives and handles like a dream. Had it only three months. When I start the car from cold, it drives fine. When I stop after a journey and try to reverse out of the drive, the car doesn't go. I have to shift into Drive and then reverse a couple of times, and then it only struggles to get out of the drive on high revs.

I did an engineering degree, but am now a chef by trade. I love problem solving, and spent two weeks on Google trying to find out the problem, and emailing Audi technicians from all over the world. I got a lot of answers, which led me to believe that to solve the problem we had to change the gearbox oil, clean the solenoids and change the shift pack filter.

Took the car to my local Audi garage, who I instructed to do the above. Initially I got a quote for €400. They changed the gearbox oil and filter, and said I still have the same problem. While changing the filter, they found an engine oil leak, which they fixed with new gaskets. Total bill of €700 euros and still the same problem with reverse. The Audi garage said that they could investigate the problem more, but that would cost per hour. Surely this problem must have been diagnosed before, and a solution should be known by now? Having read through all the forums, many people have had their transmissions changed, and parted with high amounts.

My question is why does a car that costs €70k new, and has not done over 100k miles, have so many niggling faults through reading the forums? I didn't own the car from new, and can only suggest that it was through abusive driving and neglect. Saying that, the engine is sound and it had been serviced regularly.

Being a problem solver, I will take this further and try to get to the root of the problem, and will get back with a solution.
