ESP, Anti-lock brakes, Power loss. by rka

2003 A6 quattro 93,000 mls
Winter of 05/06 the car would not stop after ignition switch was turned off, with transmission in park, until foot was removed from brake. Intermittent problem which dealer couldn't find or fix, but it seemed to occur most regularly during the coldest weather. This winter and last winter the problem has not re-appeared. Mild winters in Philadelphia area??
 
About 6 weeks ago the anti-lock brake warning light would come on after driving for 15 mins or more. On restart everything worked as normal. Happened about 4 times over a few weeks. Seemed to happen in wet weather.
 
Last 2 weeks the ESP warning light came on 3 times. Same as with anti-lock brake warning light, after restart everything works.
 
Car starts perfectly every time but within the first 5 mins of driving there is a period of several seconds when the car doesn't want to accelerate. Extremely sluggish no matter how much gas is applied. This also is an intermittent problem. Last night after about 10mins driving, 40 degrees weather, cruising on the highway at about 70mph, car lost power, engine still running, and speed slowly bled off until I pulled over to the side at about 30mph. I sat at idle for about 5 mins and then was able to drive off normally.
 
Today car drives perfectly normally until I get home and park. When I switch off and get out I notice the brake lights are all lit up. I get back in press brake pedal, no change, restart and stop, no change. I leave the car for 20 mins, restart and drive, get out after a mile, still brake lights lit, after 2 miles the lights go out.
 
Any ideas guys? Are these problems all related? Could it be a computer issue with anti-lock brake system, or a solenoid sticking in the brake system?

I have a 2002 A6 with about 55,000 miles-recently (in the past 3-4 weeks) the odb light has come on twice. The first time I had to replace the ignition coils (already done once during the recall in '03), now they are saying it's the torque converter...around $2000.00.
Anyone else familiar with this and what else I might be expecting to fail?

The code is 17125-I've had it checked by an independant service and the dealer. I'm getting estimates between $2000-$3000. (ouch).

Best advice is RUN AWAY! Dump the car ASAP. I HAD an Audi A6 2002 with 65k miles. Always serviced through Audi dealers on schedule. Last year the water pump broke, $2k later, back on the road . I take in for scheduled maintenance and I'm told I need to replace my O2 sensor to the tune of $700 dollars.
 
Last month the engine light comes on and then goes off, but the car continues to make a strange sound. I drive directly to the dealer. First I'm told it's my ignition coils, the same coils they replaced 3 years ago. They also tell me I need a new coolant container and brakes. My mistake, I tell them to fix the problem I brought the car in with first, then brakes and then coolant.
 
A day passes and they tell that the coils didn't fix the problem. They now think I need to remanufacture my engine, estimate is $7,000 for parts and $7,000 for labor, minimum. My first reaction was, STOP! No more work. After researching the problems, and checking my records for maintenance I conclude this makes no sense. I called audi of north america. They were particularly unhelpful. They claimed they would advocate that the dealer fix the problem at some sort of discount given my history of up keep. Three calls from me in week to audi of north america uncovered the real truth. Audi of North America has no desire to do anything for anyone. They told me "we stand behind the service department at the dealer". I then asked if they thought it was reasonable for Audi owners to expect an engine remanufacture at 65k after following their instructions and after using their service departments. They declined to answer, except that if the dealer says I need it, I must need it.
 
My research uncovered that I could purchase and have installed a completely remanufactured engine for $6,000. This new engine would have a better warranty than my audi engine would after audi did their repairs.
 
I also found an independent dealer that estimate that they could fix the problem for $3,500. Which is ultimately the direction I took. They couldn't explain the engine failure, except the oil change schedule and type of oil recommendation make no sense and could have cause an issue in the oil pump, which put to little oil into the engine and thus caused the cam to break.
 
When I went to retrieve my car from Audi of Mendham, they handed me a bill for $1,200. They were charging me for the coil, which didn't fix the problem, the brakes, and the coolant bottle. I protested given my prior instructions and they told me they would hold my car until I paid in full. I offered to pay for the coils, and suggested they should eat the remainder. They declined to accept my offer, even though I pointed out that it seems odd to me that I should pay for work on problems that I didn't identify when I brought the car to Audi of Mendham, since the problem I did identify was not fixed.
 
They declined to accept my position as reasonable, and again stated that they would keep the car until I paid in full. After a bit more discussion they agreed to eat the labor on the additional work, and I successfully ransomed my car from Audi of Mendham and took it directly to an idependent that fixed the car for $3,500, exactly what they originally estimated when they diagnosed the car.
 
Google A6 and engine failure and you will be horrified. I am not remotely alone. Your car is a ticking time-bomb. Sell it, trade it in, or give it away.
 
I just picked up an Infinity. Awesome car. Cost me less than I paid for the Audi six years ago, and easily a step function improvement in everything, especially reliability. Check out the A6 on the consumer reports web site the 02 and 03 years look like they were hit by a plague of gremlins.
 
I say again, RUN AWAY!

That's what I was getting a sense of...you gotta love our disposable society! Maybe I'll buy a nice late 50's something this time!
Did you get your A6 sold?

Well you can't walk away from it. The car is still worth some money. Sounds like a defective N218 pressure control valve. Could also just be very low fluid level but probably not, huh?

I have a 1998 A6 Quattro wagon and it appears that there were mid-year changes in engine, transmission and other items. I wish to purchase the correct Bentley service CD and am trying to identify which engine, transmission, steering rack, etc I have. My VIN starts with WAUJC84A8WN and my emissions sticker identifies the car as being in emissions group WADXV02. Can you help?

I have a 1998 A6 Quattro wagon and it appears there were mid-year changes. Both the C4 platform with engines AAH and AFC (2.8L V6 2v) and the C5 platform with engines AHA and ATQ (2.8L V6 5v) were sold as model year 1998. I wish to purchase the correct Bentley service CD and am trying to identify which platform version I have. My VIN starts with WAUJC84A8WN and my emissions sticker identifies the car as being in emissions group WADXV02. Can you help?
