Audi A4 Maintenance and Repair

    Are the valves clattering when this happens? If so, there is I believe a kind of pressure valve inside the valve cover that lets loose on this engine.

    If no valve clattering, next thing you need to do is screw in an actual oil pressure numerical gauge and get a reading to find out actual oil pressure, Probably anything below about 15 lbs (one "bar") would trigger the light, and if it's that low you may have problems.

    Clutches are considered "expendables" like brake pads because they are so dependent on driving habits and driving conditions. The only way I could see you getting anything is if the pressure plate literally fell apart inside the bell housing. But a worn clutch disk--that's going to be tough to prove as "defective".

    Some warranties don't even cover a worn clutch because it's considered "wear and tear." Sort of like brake pads, as Mr_Shiftright said.... Even if you were under warranty, would your particular car have been covered for clutch wear anyway?
  • Hey! Sorry about your luck. Not sure what the knocking/tapping noise could be...
    Wanted to ask you about your gas pedal response issue. Currently own a 2001 Audi A4 2.8L Quattro. When I first start the vehicle and place it in drive, I go to take off, and with my foot steady on the gas, the rpm's jump up and down. Almost seems like the engine cuts out for seconds at a time, but it remains running. This lasts only for the first couple of minutes, then seems to correct itself. Is this similar to what you experienced? Also, my exhaust gases smell "rich". Very "Gasy"? Very hard to describe. But definately not normal. Anyone else experienced this problem at all? Had the engine and tranny scanned, no codes. Recently had the engine coolant temp sensor changed.

    thanks mr. shiftright, i'll try to observe the engine clattering and do the numerical gauge to measure the oil pressure. this incident only happens during summer time and because i live in the central valley of california so sometimes the thermometer comes up to 100's F. thanks again for your advice.

    You might also try synthetic oil and see if that helps.


  • Hi everyone,
    I just bought an Audi yesterday. Its a 1999 Audi A4 1.8T Quattro Automatic (thats a mouthful) which i got by trading in my 2003 Hyundai which had ran very well(owed $6k on it, dealer gave me $2k for $4k + $7.5k Audi + tax, etc=$12k loan), and i only had maybe 2 or 3 problems with, which were covered by the warranty. I usually wouldnt, but as it turned out, i went to a tiny used car dealership which was ran by two very young guys...and got the car As Is. I usually dont make decisions on the spot, but for some reason i did(i guess i was just so in the mindset of getting a car with more cruise and ABS and i had been mildly looking into selling/trading my car for Months now).
    The Audi ran decently enough, but the inside/drivers seat felt cramped, and the ceiling is So low!! Anyway, I had read up on used car sales/what to ask and look for..and the type of Audi that i was going to see. I mainly looked up specs and recalls, not consumer's comments. I didnt see the (abundant) negative reviews as far as things falling apart - such as the timing belt - until After I got the Audi.
    I didnt drive it home because the tiny dealership said they were going to fix a couple of cosmetic things (gear shift area was all cracked/torn apart, and the cloth area that runs along the inner front windshield was falling off) and get the state inspection put on. They said i could pick it up today, but then they called me yesterday saying it wont be ready until tomorrow. Im kind of excited. But im moreso apprehensive. They couldnt fit a warranty into the loan amount - since it couldnt go over $12k. Im thinking of getting's warranty though, since they have a payment plan (they only offer the 2yr one for that specific Audi, at its mileage, and it would be $1,400 or so..but with a $299 down payment, it would be $100/month for 1 year of the 2yr coverage). Well anyway, I cant say much about the Audi as of yet, since ive only ben able to experience it during the test drive, but i should have it tomorrow...and i'll check back in with you all to give you an update on how its doing. It did seem kind of "suspect" that it was being sold for $8, is at that. But i looked up other 1999 Audis with around the same mileage, and saw many for about $9k or i figured $8k is nothing to be skeptical about. The dealership did give me a spoken warranty, so i asked them to give it to me in writing. In writing, they simply said the engine and transmission would be covered..verbally they had said "If anything happens within 30 days you can just bring it back to us and we'll fix it. We have a mechanic. But its an Audi...nothings going to happen in 30 days" Well, sounds like Audi doesnt mean perfection, based on what i've read on some online forums. I hate to have traded in a pretty good/solid Hyundai for a "high end" car that is going to be crap. That would be ridiculous. Well, i've typed long enough. Just thought id say hello and let you all know my situation, in case you have any suggestions for me as far as maintenance and such. The dealer didnt have a manual or maintenance book for the Audi, but im resourceful :) I just looked up 1999 Audi Maintenance and found some Bentley Publisher website or something that has the files online ready for print out. From the looks of it, there a H of a lot of maintenance to be done at 80k miles, which i dont know if it was done or not. One person told me i can go by an Audi dealership and they should be able to pull up the cars service records on the computer. So i'll do that. Really, it looks like much of the maintenance is stuff you "check" and replace only if necessary, so thats good. And much of it looks like the same stuff i had to get checked/replaced on my Hyundai..its just that it'll cost more. *sighs* Ah well. Its done now. Maybe my Audi will be good to me. It'll be about the first time i've ever had good luck. Thanks for reading. I'll try to come back to check any replies and give you guys an update.
    Take care.

    P.S. One of the guys at the dealership told me that the car has new brakes and new tires. When i later asked for the reciepts/paperwork, in case i want to use it's tire warranty or something, they said they dont get paperwork with it, cuz its all done by some mechanic they deal with, at wholesale. He said "We dont get paperwork for that wholesale stuff..there usually isnt a warranty on it" Sounded like a bunch of crap to me, but what can you do? So i didnt push the issue.

    **Anyway, as i was doing the test drive, i saw that the red, circular Brake light was on,and i inquired as to why that was. The guy told me that according to the mechanic who did the brake work, thats normal for Audi A4s when new brakes were Just put on. Is this true to your knowledge?** Thanks for your help!

    I hear you loud and clear. My wife is on her second Audi. Her previous Audi was an A4 1.8T. We had very few issues with this vehicle and the dealership that we bought it from had incredible service. Being pleased with the overall value of this vehicle, we are currently leasing our second Audi, but this time chose the 2006 A4 1.8T Cabriolet to enjoy the North Carolina blue skies and sun. We were driving my wife's new car home from the dealership when all of a sudden the Right Dip Light warning light came on. This means that the front right headlight is loose (not working) and the Dip Light warning light comes on a makes an annoying sound. Not a great start on a new 24-month lease!

    We are currently taking her car back to the dealership for the 4th time to resolve this issue. NC Lemon Law allows the dealership 4 attempts. During the sales process, this particular dealership (not the beforementioned) touted that they have the #6 and #7 ranked Audi technicians in the US in their dealership. These idiots can't even fix a headlight and warning light from coming on.

    This is an easy decision for us when my wife's lease ends...NO MORE AUDIS!!! Hello BMW!

    I hate to say it but I have to agree with the others about your chances in small claims court for a clutch issue, because the clutch is a wear item and not covered by the warranty even if you were still in it.

    I had an 89 Jeep Cherokee that lost its clutch within 2 years or so and the dealer refused to cover it. I took them to small claims court and rather than spend the time to appear they decided to settle for half the repair. That alone might be worth a try, as the small claims court costs are usually very reasonable.

    Of course, the cost for the Jeep repair back then was nowhere near the $2300 you are talking with for the Audi, so the dealer may very well decide to come in and contest your suit. If they do, I don't think you will prevail.

    A new clutch after 5 years isn't unheard of, but the cost of the repair and the parts kind of takes your breath away. That is why I dumped my 01 A4, I just didn't think I would be able to afford the maintenance required to keep it running well.

    I would still give it a try, but just wouldn't be too optimistic about the chances.

    Good luck.

  • Is there anyone else having issues with the ABS activating when the brakes are tapped at speeds under 20 miles per Hour. As in at a stop sign when you take off and someone pulls out infront of you and you step on the brakes the ABS shutters and the car still keeps going and does not stop. I seem to have this issue alot. It has activated atleast 35 -40 times in the last 3 months. Audi tells me this is normal.

    That may be a secondary air injection pump. Mine runs when I first start the car and you can hear it for a couple minutes it sounds like a blow dryer. My mechanic said that there was a code for it but he checked it out and it was fine, also said that thing could completely shut down and the car would still run fine, I'd just have a check engine light. I never had the rpm gauge jumping like that though. Mine just wouldn't take off after starting or pulling up to a stop sign. You had to put the pedal almost to the floor before it would respond.

    Not sure about the exhaust.

    Are parts costs for Audis truly much higher than other vehicles? I keep getting inconsistant feedback on this one?

    Am trying to decide whether to lease or buy Audi. If Parts are very expensive, may make more sense to lease.

    sir, me and my mechanic were trying to get the oil pressure reading, unfortunately we can't locate the oil sending unit, where we'll screw the oil pressure gauge. could you pls help me again, or is there any possible where i can find any engine manual of this kind of model '99 2.8 quattro. thanks

    The labor to repair most any car is about the same... $100~$110.00/hour but the actual hours spent to repair an Audi usually runs more. Even the hourly charge doesn't mean much these days, most auto repairs are "menu priced" out of the repair manual that most all shops use as a pricing guide.

    Parts for Audis aren't that much more if purchased on line, atleast for the smaller maintenance type items, but the larger major stuff such as alternators, air conditioning compressor, starter, are probably 20 to 30 percent more than some of the more popular Asian and Detroit makes.

    Also, there are less shops around than can work on an Audi, and this makes for a more expensive repair overall.

    Leasing will be smarter if you tend to change cars often, drive less than 35 to 40,000 miles in 3 years, can write the leasing expense off your business, and take good care of what you drive. At lease end, you will be charged up for excess miles and unreasonable wear and tear to the vehicle.

    You might try eBay for that. I'm sure the dealer sells the factory manual, but that might cost a bit and have far more info than you care to know. Oil sending units are often near the oil filter.

    i'll try, thanks again

    Hi everyone. I have a Audi A4 (1995), from last few weeks it is having a very strange problem. There is huge air pressure in fuel tank, looks like that fuel tank pulls air in from fuel tank cap. When i open fuel cap car breath easily and run smoothly but with fuel cap on it pulls air in and rev goes high. If anyone had same problem or know about this... then i need help. I showed to three mechanic but no one could diagnose.
  • shom1shom1 Posts: 5
    Thanks for the feedback. The dealer stated in writing that the pressure plate was defective, causing damage to the clutch. My contention that I only drive freeway miles is supported by the original brake pad thickness being worn down only 16% as measured by the dealer, also in writing. My last clutch (Toyota Supra) had no repairs whatsoever when I sold the car after 18 years and 145K - I know how to drive a clutch in other words. Additional feedback would be more than welcome. I file my case tomorrow - there most definitely ARE implied warranties on cars, plus equity doctrines under the common law.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,403
    I'd try a new cap first off or if your car doesn't use a vented cap system then whatever device vents your gas tank. The gas tank is supposed to pull air in from the cap OR some other venting system. Your gas tank must vent or it will collapse from vacuum.

    Lately my 1998 A4 has had a wind problem, once I go over 40 I hear this loud wind sound. Other thing is when I first turn the car in the morning I get this strong fume smell, but then after driving it for a while it goes away. Any input on this would be appreciated.
