2011 Audi A5 owner. I am hanging onto it for dear life as manuals are hard to find anymore with new cars. Anway, it only has 115K on the odometer, but its starting to really burn oil. It used to be only adding one quart between service intervals, but now its two. I just had it in for service about three weeks ago, and the indicator is showing down about 3/4s already, and I can smell oil when I walk in front of the car just after a drive. Nothing on the garage floor for oil, but my service guy just shrugged it off as saying that its normal, and I am lucky compared to other Audi owners of the same vintage who have been adding 2-3 quarts between service intervals. Anyway, is there anything that can be done, minus a new engine, to keep it going with only minimal oil burn? Anything any of you found to fix/help?
Compression and leak down test may help zero in on whether it's valve guide seals or piston rings. FWIW, I had an oil burning issue with my truck because I hadn't changed the PCV (because it was clogged) so perhaps look into that as well
Get a better mechanic. If you’re smelling oil, it’s not burning, it’s leaking/blowing out. I’d suggest breather/PCV and turbo as points of concern.
I have owned 2 2013 Audi A5s, and 2 Audi A5 sportbacks 2018, and currently in a 2019 Audi A5 Sportback. They do burn oil, especially after 100k miles. I started to have problems with my 2013 models after 100k. Still minor stuff but expect to start dropping some $ to keep em going. If you are smelling oil in the front of car after driving you have a leak. The reason it is not showing up on the ground is these things have a huge bottom engine shield that will trap the oil and anything else that may drip. When you drive the wind probably pushes it out. These cars burn oil, that means it only comes out the exhaust as soot. Your rear bumper is probably getting dirty more often. My Audis are all black and I always keep them very clean so I dont notice. I would have a service person put it on the lift, pull the shield and start looking for a leak.
Sounds like this is a known issue with that vintage of engine and come to think of it, I remember my wife's 1.8T GTi doing the same. From my 30 second google investigation, the 3 most common fixes are: 1. crankcase breather replacement $ 2. new pistons and rings $$$$$$$$$ 3. new engine $$$$$$$LOL$$$$$$ Like other have suggested, I'd check to see if you get any smoke coming out of the exhaust at start up. This will usually tell you if it could be a piston ring issue. If no visible plumes of smoke, I'd move onto replacing the crank case breather and doing a compression and leak down test. You'll also want to check the underside of the car to rule out a seal or gasket that's leaking and contributing to the loss of oil. If that checks out and compression and leak down are in range, then figure out the consumption after the breather replacement and if that's livable. If not, the answer is always: LS swap.
You need to figure it out if it’s burning it or leaking it. if burning a lot of times a treatment with a liquid that escapes my mind helps unseat the stuck piston rings. I did it on my golf R as it was burning a quart of oil every 1500 miles and seems to have helped a lot. If you’re smelling oil than valve covers leaking is a big one.
2.0 I presume? I had a 2010 A4 back in the day with the same issue and Audi was going to rebuild the engine. Ended up trading it off before I had it done though. Super common on those engines to have issues like that.
I have a 2016 A5 with 86,000 miles on it that uses about a quart every 1000 miles. There was a class action settlement on oil use but unfortunately was for years earlier than mine. Dealer claims that carbon build up causes the oil rings to stick in the pistons and not clean the cylinder walls. They offer a chemical soak that supposedly cleans it up and I have found some information online that supports this. They want $1400 to do it so I haven't tried it yet.
Yeah, the fsi/tfsi are notorious for oil thirst. And carbon buildup. Some companies even office services to remove the intake and do Walnut blasting. My dad‘s 2.0 ended up using a qt every thousand kilometers before he bought a used spare engine. My 2013 4.2 L needs a quart every 3000 miles which I think is OK considering the comparable data
Given that the vehicles stated in this thread run from 2001 - 2019, I'm pretty doubtful they are much better in 2024.
My 2018 and my 2019 I have now (55k miles) have never had to add oil besides doing oil change. It is a different motor then the 2013 A5 I had (both 2.0) but motor is different. Even my 2013 models I never added oil besides the oil change. Honestly I have always bought luxury cars besides my trucks and have been pretty impressed with Audi (hence I am on my 4th one). Super fast and light cars, great on gas if you dont drive it pedal to metal everywhere. Nothing but positive things to say about them. Working on buying my first R8!
ouch...looks to be an issue with the rings, and you're past the extended warranty :\ https://www.a5oc.com/threads/2-0-tfsi-oil-consumption-problem-summary-and-faq.90849/
I bought the 10 year extended factory warranty. Evidently, a quart every 1000 miles at 86,000 miles is within their specs. I think they said it had to get to a quart every 700 miles, so hey, I got 2 years left on the warranty. I think it will get there.
