2004 Audi A4 3.0 - Oil pressure Problem

I bought a 2004 Audi A4 in March of 2008. It was still under warranty at purchase with 26k miles. I had an early 45k service done in July of 08. This past week, the oil pressure light came on and the audi dealer is telling me it's "likely" oil sludge and that the pump needs to be replaced...for a cost of $2,800 USD. I'm disputing my responsibility to pay the repair costs. I have contacted an attorney and have also filed a complaint through the BBB. Audi customer service has stated that it's usually the Service Manager who is able to arrange what Audi will cover for these types of problems...that the SM will reach out to "his contacts to arrange an amount to cover." The SM stated so far that he is going to see if he can get Audi to cover half the cost based on my circumstances. I do not feel that is enough. Any advice?

    Thank you for your quick response. The Red oil pressure warning came on after about 30 minutes of driving and did not come back on after a restart (I turned it back on after checking the oil level and then had it brought to audi). I have seen no warnings of sludge (flakes on the cap) but that's what the audi service manager has stated. There is no indication that the oil pump has been damaged. It seems that they're not telling me everything. They provided me with no update today.

    I know, for an oil doesn't make sense. I asked the same question; the service manager stated it's a labor intensive job. All services were done at a certified audi dealer (they have it all in their computer). I didn't get your question about whether I'm repairing the car from the selling dealer.

    I just recently moved so its not the same dealer but I did buy it from an audi dealer.

  • Aaron Perry Jun 01, 2009

    UPDATE: Audi decided to pick up the costs for all the parts giving me a tab of $1100 out of $2800. I was still forced to pay for labor. But that's still a huge difference. This shows that they do feel somewhat "responsible" to assist audi owners in fixing these types of malfuntional issues. Thanks for everyone's comments/help.

    To verify proper oil pressure: 1. Run engine to operating temperature. 2. remove oil pressure sending unit (usually a round module w/connector (wire). 3. connect oil pressure gauge in place of sending unit/module. 4. start engine and watch gauge (usually minimum oil pressure should be no lower than 10 psi at idle). If there is sludge, pressure will be much lower. Comparison of oil pressure when engine is cold (50 psi +)

    Has anyone 'verified' low oil pressure? Does the oil pressure light come 'ON' when you first start it up cold?... or does the light come 'on' after the engine warms up? Here's a description of 'sludge' in the crankcase - oil pressure is normal (good) until the engine warms/heats up. Sludge can be cleaned out by removing the oil pan -- it does not require replacement of the pump unless the pump has become damaged.

2800.00 for an oil pump? Sounds expensive. Is it only for the pump or is other work involved? There are hoses that deteriorate that have to be replaced and an engine flush that usually goes with that repair. Also your engine may have to be replaced if there is bearing damage to the camshafts or crankshaft. This is a common problem with 1.8T's. You are not the original owner,so are you repairing the car from the selling dealer? It make a difference when your trying to get assistance. You also must have proof that all services were completed, preferably by a dealer. If you have all that and still only offer half take it and be happy!

    I meant are you having the car repaired at the dealer you bought it at? If you are it give the service manager more reason to help you. You never say if you bought it from a dealer. was it a private purchase?

well do you have documentation that you changed the oil every 4 thousand miles or less? If you do the the dealer should cover the expenses. If you did not do the oil changes as required or do not have the proof then the dealer is being more than fair as the failure would be because of your lack of maintenance.

My odometer is 110,000 that a subaru 2008 outback is that bad,i bought only last week

  • Not to bad. Outback is a good vehicle. With so many miles and it only being a 2008 I am inclined to think this was a highway traveled vehicle more than in town. This is good because highway miles is far better on a vehicle than in town miles. Some maintenance you need to either confirm has been done or inspected to see if it needs to be done. May also have some warranty with it to but warranties often do not cover preventative maintenance.
  1. Transmission flush - 20,000 miles
  2. Transmission Filter - 50,000 miles
  3. Radiator flush. - 30,000 miles
  4. Air filter. - As needed.
  5. Oil change. - 3 months or 3,000 miles - usually right away with new vehicle.
  6. Emissions clean. - 25,000 miles
  7. Brake inspection. Right away with new vehicle.
  8. Serpentine belt - 50,000 miles inspect often.
  9. Alignment check - Check is often free.
  10. Tires.

We just purchased a 2008 Audi a4. Sometimes when I drive the "Middle brake light warning" comes on and beeps. The car recently had a 20k service, new tires and new brakes done before we purchased it.

if it is a 2008 why don't you ask a dealer? it has to be under warranty. Asking an audi mechanic is light years ahead in common sense as opposed to asking strangers to look in a crystal ball.

Premature oil pump failure 04 A4 3.0 Quattro

Absolutely - the 1.8T engine is known for sludging issues. If they diagnosed oil sludge then your engine is covered no matter the mileage. The oil sludge builds up in the 1.8T no matter how well cared for it is, and the sludge can block the oil pickup screen on the oil pump (it's an extremely fine mesh), causing oil starvation and taking out the engine in the process.

Go to and do a search there for "oil sludge" and the information will come up. You can learn all about it there. But if your engine has the sludging, and you have receipts proving the oil was changed at the proper intervals, you will get a new engine free of charge - one of the members there is an Audi technician and I remember him posting that he'd changed out a 180k mile engine under warranty due to sludge.

Oil Pressure light comes on....

The oil light should come on when the car stalls, this is normal. The stalling isn't, do u have a warranty thru the dealer u purchased it from? Most have at least a 30 day warranty. A 2004 should have included some type of warranty. U should bring it back, and they should correct the problem at no charge if u recently purchased it, and there is some sort of guarantee. Let me know if there is.
