Audi A4 Maintenance and Repair



  • About my car:
    Audi A4 Convertible 2004 (appx. 46000)
    4 year lease

    Oil Sludge

    Four days ago, my car just suddenly dies in the freeway and it's towed to the dealer. The problem, "Oil Sludge" they call it. So the dealer asks for my recent service receipts so I provide them with all my receipts and I have them done with synthetic oil. Some I've got it done outside of dealer and some from the dealer. Later, they decline the warranty due to lack of info and that I went over 2000 miles on one particular time with the service. Now they are asking about $7000 to fix the car. In this case, what should I do cuz I really don't have that kind of money. This really doens't make any sense to me cuz I had cars previously and they never break down even I go over 10,000 miles! Is there anyway I can talk them into a warranty? And is there any way I can just return this junk?

    I have been ahving trouble with my 2002 A4 1.8T radio reception. I have the bose system and everything works great but the radio is not getting any reception. I asked the dealer and they said I need a booster, which is $300. I was wondering if anyone has had this problem and if they have any advice on how to fix it without spending $300 on a booster.
  • My clutch on my A4 is going out for the THIRD time at under 32,000 miles. I bought the car at 13,000 miles and had the first clutch go out at 22,000. It went out again at 28,000 and had to spend the $1500 to get it replaced. I thought it must have been a fluke but now it is going out in under 4,000 miles since replacement (2 months). I have been increasingly careful with the clutch and Audi will only tell me "wear and tear". Does anyone know how of any problem this might be, or how to get Audi to actually try and help me??
  • My 2004 Audi A4 Quattro 1.8T did EXACTLY the same thing! I had previously had the car towed to the dealership because my oil pressure warning light illuminated. After keeping my car for about a month (no kidding) they called and accused me of stealing their loaner car. I was like i'll drive the damn loaner car until they call and tell me whats wrong with mine. They never called and so I kept the thing; which was really kind of funny. Eventually, they informed me that all it needed was an oil flush and oil change, even though I had been having the oil changed with synthetic oil within the maufacturers suggested time periods. I did this and had no problems for awhile, but it ultimeately died when I was on a roadtrip in the middle of nowhere. At first they refused to honor the repair; which required a whole new engine! They said they had no records of me having the oil changed. My problem, was that I did not do this at the dealership, although it would have been free at the time. The dealership was just too far from my house to justify the drive and time vs. going to Jiffy Lube or something like that. I eventually was able to round up receipts to prove the oil had been changed regularly and they eventually did pay for the new engine under warranty. Shortly thereafter I received a form letter from Audi which spoke to a widespread defect involving oil pressure and oil sludge problems. The letter said if you had out of pocket repairs for the problem you would be reimbursed if you provided receipts. I wish I had saved the letter, but I don't have it anymore. That might be something you should look into.

    I'm not exactly sure, but I think that this might fall under your state's "Lemon Law" if it should have one. You may want to contact the Dept of Motor Vehicles about this. I know people who have gone as far as the Attorney General's Office in similar matters and they will investigate your complaint.
    Wear and tear seems to be Audi's mantra. Two weeks after my clutch went on my car with 54,000 miles and having it replaced, the worn brake pads light came on and had to have the front brakes of the car redone. This after they told me just before the warranty went off that the brakes were fine. They threw me a 10% discount on my bill as if that would make it right. I swear Audi programs their computer sensors to kick in after the warranty runs out. Always an adventure with this brand of "fine German engineering."
  • Here's my most recent problem with my A4, which seems to need repair at least monthly. It's a piece of crap. But I digress. I have a 2002 A4 (out of warranty, of course). While driving, the Malfunction Indicator Lamp (MIL) came on -- steady, not flashing. I made it to my destination without a problem, and the car feels like it's driving fine. Any ideas what the cause might be? Thanks for your help! :lemon:
  • Hi

    I have an A3 98 TDI 3 door, my drivers door window has stopped working and i cant seem to close it. I wonder if anyone can tell me how the door panels can be removed as i think the window may have come of a runner as the electric motor is still working but jams when trying to close.

    The light came on in my 2001 A4 at 51,500 miles. Just after the warranty expired. The dealer wanted 125 just to read the code. I found an independent shop to read the code for 88. They then fixed for a mere 88/hour in labor. All told it cost me about 180 for the repair. There was a vacumn leak and they replaced two small hoses. Not too big a deal, but with all the other problems I had been having and knowing that they would likely continue and start to get expensive, I went ahead and traded the car in.

    Autozone or somebody else might be able to read the code for you on the cheap, but my guess is that whoever does the actual repair is going to charge you to read the code anyway before they start work (which would make sense). As long as the light is on steady (according to the 01 owner's manual and the dealer) it was ok to drive. If it flashes then you need to have it towed because you could do some damage by continuing to drive it. I don't know about the 02 though.

    Good luck.

  • When I did service, I asked the technician, he told me that all the 2005+ / 2006 Audi A4 Quattro come with Mobil 1 Regular oil which is 5w-30 ( and he said you could use any other brand as long as it is 5w-30).

    However you can also use Mobil 1 synthetic 0w-30, but that's not neccesary. (It will be more durable but not provide better performance...that's what he said. Mobil 1 synthetic is used for the purpose of avoiding the sludge problem on A4 1.8T)

    Anyone has comments on this?
  • My heating system recently packed up on me (conveniently in the winter!!!). It blows out no air and occasionally (if I'm driving round a corner, etc) it switches on suddenly.

    Any ideas what could be wrong?

    Hi gang, well after picking up my car last week due to the engine light being on, I was surprised to see it again this morning!!! I called the dealer and basically I was told that the engine light can come up due to various reasons, among them: gas cap not being properly shut, misfire of the engine, vacuum problems, etc, etc, etc.

    I've told them that this is the last time that I will take the car for the same reason (this is the third time engine light is on), and if the engine light comes on again, then I will start Lemon law proceedings. Do you guys think I'll have a case if this engine light keeps appearing??? The car runs fine, but it is so anyoing to keep comming back for the same reason. Have any of you experienced the same problem so many times in such a short period of time?

    Your feedback will be greatly appreciated.

    Hi recently experienced a similar problem with my Audi A4 Quattro 1.8T 2002 that you have met before.

    The steering wheel vibrates at certain RPM 1200 - 1400. Above of below this range is fine. I just wonder how did you solve the problem. Any shave will be very appreciated.
  • Audi currently recommends 5W-40 Synthetic oil. The oil must meet the VW 502-00 standard. See the below link from Audi, listing those oils that meet the standard.
    This standard was implemented as a result of the sludge problems experienced a few years ago. Neither Mobil-1 0W-30 nor 5w-30 meet the standard.
  • sorry to hear all the bad stories about Audi's. Mine is similar.

    I bought my A4 of lease from the dealership in 2003. Since then I have poured an additional $8000 into the car for repairs. The last straw or go around, they are claiming I need a new computer ($3000 with labor). Enough already!! I subsequently took the car back and got a second opinion to find out the dealership mechanic failed to put back parts of my car. They were kind enough to fess up and put the parts back free of charge, but what kind of shady business in this? I would Never NEVER recommend an Audi to anyone that I like. :lemon:

    Most folks I hear of on the Audi boards use the Mobil 1 0W-40, the European spec Mobil 1.

    Check the bottle as I believe it specifically lists the VW/Audi specs.

  • Be sure to check online for the lemon laws in your state. In Georgia 3 times is the charm. When the engine light comes on, the onboard computer should log what the problem is. I would ask the dealer for this information.

    Just wanted to share with you all my frustration (I'll tried to remain calm). I took my car this past Friday to be serviced(engine light on again). When I got to the dealer, I immediately requested the loaner, which I had reserved since the previous Monday when I made the appointment. The service manager indicated that they could take a quick look right away and perhaps have me out of the place in 30 minutes. After waiting patiently for 1 hour I went into his office to check on the status (bear in mind that I had already explained to him that I needed to get back to my office ASAP). He said that the mechanic found a leak in the car and that they needed to order a part (did not have the part in stock). Very calmly he said to bring the car back on Monday!! I cant write here what I wanted to tell him, but I guess he did not understand the purpose of a loaner (Dealer keeps the troubled car as long as they need it to get it fixed and us customers get a loaner to move around until the car its fixed....I explained that to him just like that). He kept insisting that I come back on Monday. At that point I thought that either he got early signs of mental retardation or my message was not being understood. I told him to take the car off the lift and I was going to another dealer.

    Today I sent a letter to that Dealership Service Manager, and cc Audi of America Customer Relations as well as NJ lemon law division (this is the third time that the engine light keeps coming on). I dont know if you guys have received such poor service at your Audi dealership, but I would never recommend you purchase a car from Flemington Audi. While the sales person was terrific and the sales process was excellent (not complaints there), the service dept has really left a very bad impression on me.

    I guess that after being treated one way by my wife's dealer (Lexus ES 300), you do get spoiled. I always have gotten loaners even from Miami dealers when we travel(we purchased the car in NJ).

    I had it with the poor reliability of this car and the crappy treatment that the service department seems to give its customers.

    Thanks for listening and I will be counting the 26 months or 780 days or 18,720 hours left on my lease, and I will return this car with a big smile. Never again!

    Thanks all

    p.s. I would like to know what type of experiences you've had when requesting a loaner from a dealer different than where you purchased the car. Life Quality Audi in BayRidge Brooklyn called me back to let me know that they "stopped" the loaners program for customers that bought the car somewhere else!!! While I understand that the "in-house" customer should get preferential treatment, at least they should make an effort to provide others "outsiders" with a loaner. Anyway, just let me know if you guys are able to get loaners from outside dealers.

    Thanks for listening to my cries :cry:
