Audi A4 Maintenance and Repair



  • Did you change your oil recently and did you use a non-Audi oil filter or some budget quick-change filter? If so, this can be a problem with the V-6 engine and induce valve noise. Just an outside chance---it has happened.

    That is correct---there are no adjustments to the valves, so it's possible you have defective lifter or lifters, or a worn camshaft. Please check your oil level and if you're due for a change, get an Audi filter and see what happens.

    Wendyx, did you solve the front end shuddering on your A4? Mine does the same exact thing on acceleration. Not brakes, they're good.
    Thanks PEH

    My 2003 A4 Cabriolet shudders upon acceleration. Not a brake problem or wheel balance. At any acceleration speed....0 to 30 or 40 to 50 etc.
    Anyone have the answer?

    lyallbarbour: Shiftright is right, the best manuals would be obtained from Bentley, IF they happen to publish one for your model. I have a Haynes manual for my 97 A4, and like Chilton, they are fairly useful for your basic repairs/maintenance. You can also check with a dealer for a full-blown manual, but that's going to be big bucks. I think you meant "$100 to 200", not "$100 to $2,000", right? audiphile3
  • My 2004 Audi A4 3.0 convertible's check engine light came on and I just had the ignition coil recall performed. My check engine light continues to come on...the computer kept showing misfires on Cylinders 3 & 4. There was about a 5 second rough start when the engine was started cold. After a week in the shop, the dealership says it is a coolant leak in cylinder 3 only...they are no longer seeing misfires on cylinder 4. They want $2400 to take the engine to a machine shop and THEN will give me an estimate for the repair assuming they find the problem. Any advice?
  • My A4 Quatro fuel sensor stopped working just after the 50,000 mi warranty expired. The low fuel warning light is on all the time, the miles remaining indicator is not accurate and the fuel gauge does not work. I use the digital trip odometer to show how many miles driven after a fill-up. My dealer in CT told me I am out of warranty and thus have to pay possibly hundreds of dollars just to diagnose the problem by plugging into their diagnostic machine. I have not seen any discussions in various forums about failed fuel sensors in an A4 with less than 100,000 miles. This should not be a part that wears out/fails so quickly. I will talk to the local service manager again to ask if they will diagnose the problem at their cost and fix it at their cost. If they argue with me, I will try to get a contact in the US service management team. I have the Haynes manual to show how to access the fuel tank to replace the sensor (2 sensors in the fuel tank because of AWD). I have the means to replace the sensor outside of the local dealer, but would prefer that it be handled at the dealer level. It seems to me they would want me to purchase another Audi when I am ready for my next car. Any recommendations from the forum are appreciated.

    simonmj: Just like a medical problem, I would say "get a second opinion" Sorry, I'm not a big fan of dealerships...some are good, some are outrageously bad. Find an independent Audi specialist and ask them to check out this issue. I find it ridiculous that you should spend $2,400 just to find out it there is even a problem. Personally, I would put some high-quality "stop leak" in the cooling system, but that's only MY opinion. Some of those products are very effective at solving this type of problem. In any case, you should certainly attend to this relatively quickly.

  • Our 2006 Audi A4 Cabbriolet 1.8t has begun to shutter and shake under light acceleration at speeds of around 20-30. It seems to happen most often while turning left through an intersection, and then accelerating away from the turn. Our beloved Audi only has 39,000 miles on it, we have no SES lights on, and have not taken it to a shop yet. Any help from you guys on what you think it might be would be greatly appreciated!!! We love our car, but are scared about what this shuttering could mean. Please help us!!!!

    Likely not a transmission issue but rather a CV joint or wheel bearing. Given that it happens only under the circumstances you mentioned. A good mechanic should be able to diagnose it quickly and if it's a CV joint the damage should be visible.
  • Ok, I am in the market for a 2007 Audi A4 2.0T quattro with 40k miles. Fun to drive, but I am concerned with the cost of maintenance. I have heard mixed reviews. The other car I am considering is actually a Nissan Murano. I know the Audi is much more of a driver's car, but I would like to get an idea of what sort of premium I would pay to have such a car? Oil change prices/etc? Or is it only if/when a repair is needed that the higher costs show their ugly head? How often is a repair required (guesstimate). Thanks!

  • Your best approach with an Audi is scheduled, methodical, pro-active maintenance. In other words, the car goes into Dieter and Hans in the spring and fall, whether it seems to "need" anything or not. This may seem over-indulgent, and might cost you $100/$150 a month, but believe me, it's the cheap way out if you have an Audi out of warranty.
  • thank you, I guess another question is how much more should I guess I would be paying for maintaining the audi over a 5 yr stretch vs a nissan murano... :confuse:
  • You might find the Edmunds MAINTENANCE COSTS TOOL a very handy way to answer that question accurately.
  • Hello everyone,

    Yesterday my coolant light came on. I checked the level and it was right at the low line. My dealership was closing before I got off work, so I just drove home, planning to pick up some G12 today. I woke up, and checked the level of the coolant reservoir, and to my surprise, there wasn't anything registering at all.

    I found no sign of a leak, of any sort, nor could I smell any hint of coolant that may have "burned". I just bought the car, used, two weeks ago from a dealer. It's a '04 A4 1.8 Quattro. Any ideas?
  • Have the cooling system pressure tested and see what's up.
  • I am currently shopping for a convertible. My search began with BMW's but I quickly changed my mind to either an Audi or Saab.

    In my research, it seems they are close. Saab's get high reviews, while Audi's are mixed.

    The styles are similar as well. Prior to purchasing, I am now at the phase where I need to research maintance and issues. Oil changes, true gas mileage, problems etc. Can anyone who may have owned either of the above shed some light on these questions?

  • I have a 01 Audi Quattro. I'm in need of help with my vehicle. I hope somebody will answer to this. My air suspension light came on this morning on my Vehicle and i noticed the rear is just sagging and wont come up at all... I called the dealer but nobody has got back to me yet about it.. What should I do.. Any recommendations. Money is no option for me. . Just want my car fixed.

    The cost of repairing air suspensions is very high, leading some who are faced with your decision to convert to a conventional (no-air) suspension. There are companies that make kits for this, but I can't think of the name(s) at the moment. Owners who have taken this route are generally happy with the results, and the savings.

    Between Edmunds, Google, and independent Audi specialists, you should be able to find the best solution for your car.
  • Hello KristyLou.. If your air suspension light came on you should have checked it immediately.. Something was obviously going on with the vehicle that needed to be fixed. Im sorry to hear that your rear air suspension has went out on you. And i can go ahead and let you know that the dealer price is going to be crazyy expensive.. around 4-7 thousand dollars. The reason i know this I have a 06 Audi All road and my air suspension system went out as well in the rear.
