The car is beautiful and otherwise drives extremely well, but used a great deal of oil right from new. I really didn’t take it to heart just how much, but after some years, I finally admitted to myself it could be a whole quart every two weeks!

I followed the news about a class action lawsuit relating to a great number of Audi models AND BMWs having this problem of burning oil. I heard many Audi dealerships claimed it was normal in a performance car to use a quart every 1,000 miles. But I was able to keep up to date with other Audi owners through an Audi forum. The lawsuit ended up applying to cars under about 6 years old, and only those under 80,000 miles would be eligible.

So as the lawsuit resolved, I was aware they would take some convincing... the procedure was to bring the car in, once you’re accepted into the verification program, and upon changing the oil, they would precisely measure the oil returned to the car. Next, you drive until the yellow oil light comes on, which I think means you’ve burned a quart (liter, actually). In fact, this also indicates you only have a quart left till the red light would come on.

So once the yellow light comes on, you return the car, they measure the exact contents of the engine, and if the results showed excessive oil being burned, they’d change your pistons and rings for free.

The dealership did exactly that, although they called during the overhaul stating the timing chain was excessively worn, so at my option they could replace it (while they had the engine open already), at just the material cost of $400 (the final bill was $509 with tax and adjoining parts).

A subsequent class action lawsuit I signed up for related to the timing chains failing prematurely. That one also paid off, and I got my $509 back.

Obviously I’m very satisfied with the outcome, since I now effectively have a new engine. I’m not complaining, in spite of using 2 1/2 gallons of oil in top ups between (10,000 mile) oil changes. Yes, that was “gallons,” in other words, 10 quarts!

Audi had a class action law suit regarding excessive oil consumption. I was never notified. When I noticed excessive oil consumption (oil light coming on every 1,000) I finally called Audi. That's what I found out about the class action law suit which was already settled. I've already spent $900 on new parts for them to even diagnose the problem. After the replacement of parts, oil has to be added every 100 miles. My car has been at the dealer in/out for about 20 days. The finally found the problem to be a broken piston in Cylinder 2. Audi will not take responsibility. Now I have to replace the engine at $12,000 - $13,000. This is a rip off.

NEVER BUY AN AUDI. Their business practices are questionable. They will try their best to get out for any responsibilities. They don't stand behind their products. No wonder they lag behind BMWs and Mercedes.

I just bought my 2011 Audi A5 2.0t with 75697 miles on November 6th 2018 with fresh oil change. Drove it for a while. Around around 2 weeks later, light come on low oil. I ended up adding 4 qts, so I thought damn that's a lot of oil. but I thought it'll be ok. About 2 weeks later the light come on again and guess what, 4 qts of oil needed to be added AGAIN. This is insane! I have never own such a oil guzzler. I went on-line trying to find out if that's something easy to fix, just to find out that Audi knew all that time that this is a problem on the models from 2008-2011. It seems to be that Audi don't care and will NOT fix your ca,r regardless of what you throw at them, they are NOT standing behind the products that they make. What a shame, it's a nice car with a pretty bad problem. My oil change is not due till it reaches 82679 as per dealer suggestion on paperwork and I already poured 8 qts in. So I just wonder if someone has the same kind of problem and if they had the dealer fix it. I would appreciate any thoughts suggestions. Thanks

A5 2.0t

  • Manual transmission
  • 46,510 miles

A D V E R T I S E M E N T S

Purchased 2011 Audi A5 in April of 2016 from The Honda Superstore of Joliet. The car was found thru Car Fax as it was a single owner with a clean record and all maintenance information. All maintenance was done by Audi Westmont. This car was low mileage and offered at a fair market price. It test drove great and looked clean, hardly driven. It only had 46,510 miles from original owner. I drove it home on April 9th and within a mile of my house the check oil pressure light came on when the car came to idle. I took it immediately to Team Audi in Merrillville, IN. They said it had a bad sensor and all pressure tested fine. I drove again with no problem. Over the next 8000 miles the light came back on two different occasions, and I took it to Westmont Audi to investigate. They told me again it was a sensor and the oil pressure was fine. In addition a oil consumption test was done with no problems found. Now at 54,000 miles they dropped the oil pan and told me there is metal in it. It needs a new engine at a cost of $13,000 for just the engine. I contacted Audi North America for assistance and they have told me it is my problem.

I can assure you this will be the last VW / Audi ever purchased. They don't stand behind their product and as has been in the news, are a less than desirable company trying to cheat their way to the top.

A5 2.0t Quattro

  • Manual transmission
  • 27,000 miles

So, I bought my car used from a VW dealer with 24K miles 5/14. I never knew about the oil consumption problem but the light started going on at 27K. I added oil, and then it came back on very soon again. I added more oil, and so the cycle began. Now, since one cannot measure the oil on one's own, I never knew how much it had in it, so I did not run to add more every time the light was on, and it was just on a lot. Not being informed as the second or later vehicle owner is a real flaw in the notification system. Just follow the VIN. We are in the modern electronic era now, after all!

I should mention that I have been back to the service center at the dealership where I purchased the car on at least two occasions since the suit was settled, and they never once mentioned the oil problem or the fix!

So, just over 34K miles I took it in to Audi for the 35K tune-up where I learned all about the two-part test to confirm the oil consumption diagnosis before Audi will pay for the fix. Now I can only hope that I have not caused damage to the engine by starving it of oil over the many months. During the 7 months since it went on I added 4 qts. of oil, and just assumed that the light would go off because they said they could not turn it off originally when I brought out in to have the oil changed the first time because they did not have the right tool.

Why is it so f____ unreasonable to expect people who have useful information to exercise it?! One more reason never to buy a VW again!

Thanks for listening, LH

cambridge and tension chain failed inspection at 60k miles

I'm not the first one to complain of this problem. Audi found the potential issue as my oil light was coming on every 1000 miles after 50k mile so they replaced the pistons (at no cost to me because of ongoing complaints and my history) however they say the cam bridge and chain tensioner failed inspection! AND my water pump has a slight leak! The car is less than 5 years old! There could be a potential class action suit in the Cambridge problem. I owned a BMW 325 for 8 years without one issue! NO MORE AUDI'S FOR ME
