Not sure what warranty coverage is in England(?), in the U.S. it's 4 years or 50,000 miles and the powertrain warranty is more than that. Can't remember off hand what it is though. I would recommend taking it to an Audi dealer to get part 1 of the oil consumption TSB done. It basically says "Upon customer complaint of excessive oil consumption, perform the following TSB" No other authorization is needed. This replaces the "PCV" valve, front crank seal and reflashes the ECM, bringing it to 2013 specs with reduced crankcase pressure. An electronic oil level measurment will be done, THEN, you drive a minimum of 630 miles and another measurment is done. This is all performed with a program on the Audi scanner.
If the low oil warning comes on before 630 miles, it's perfectly safe to drive the car. If the oil level gets too low, the cluster will warn you before any damage is done. Anyways, if it comes on, go to the dealer and either have them perform part 2 (the 'after' measurment) OR add oil and record the amount so it can be figured into the final results when it's done. One of two things will happen then. In a majority of the cases, the PCV and reflash have solved the oil burning. If it doesn't, the tech will make a TAC case and the tech-line engineeers will authorize replacing the piston rings.
Basically, unless warranty is different is the U.K., you should be covered. As always, the dealer and the technician MUST follow the procedures and policies of Audi or the claim will get charged back to the dealership. That's why they sometimes "seem" to not want to fix customers cars. It's not that they don't want to or know how to, it's that if they did it would have been for free. No one likes working for free, do they?

 

That is a very good explanation of the process. I had mine done last week. It was 310ml per 1000km. My Audi dealer is very good. It was no trouble at all to get the test booked in. They explained what they were going to do and the whole test (1000km) was painless. They told me if the car indicated it needed oil to pop in and they would sort. My suggestion is to talk to an official dealer and see what they say. You have nothing to lose by asking.

 

lads and ladies, a5 tfsi here its the dogs watsits for a car but my oil consumption that of a medium city in uk, into dealers tomorrow to sort, dont stop hounding them, this is a serious fault.

 

I purchased a used 2009 A4 2.0T on July 31, 2013. The vehicle had only 32,000 miles on the odometer but was out of warranty. I experienced the exact problem described in this thread. Once I read up on the oil consumption problems people have experienced with the engine, my heart sank. Fearing the worst, I contacted my local dealer and described the problem. I had purchased the car from a VW dealer, so the Audi dealer had no skin in the game.

Over the phone, the service manager of the Audi dealership took down my VIN. He immediately found that the VW dealership had sent the car to his service department for factory-sponsored service - one month before I bought it - to resolve an oil consumption problem. The service manager told me that the usual fix is a special PCV value replacement, but about 1% of the time defective pistons are to blame. He said that Audi has been committed to resolve the problem in either case, and it didn't matter that the car was out of warranty.

I took the car in for service and it was determined that the correct PCV valve had not previously been installed, due to some confusion about a changed part number. The correct PCV was installed, free of charge, and I got a complimentary full service wash and vacuum. That was several days ago, and so far the oil level has not budged off the "max" line. Fingers are crossed.

I know that some of you have had different outcomes, but I only have the highest regard for Audi in owning up to the problem, especially on a four-year-old car. I am truly impressed.

 

Since my pistons were replaced the car has done 6500 miles on one liter of oil and still going strong.

Although I have participated in this thread, I admit to jumping to the most recent post this morning.

Has anyone explained how the 2013 motor (2.0T) is different than the motors in 2008 through 2012 A4s and A5s? I was told by one tech that the 2013 motor is "new". That Audi learned from its mistakes.

Anyone?

 

The engine is the same as the '08-'12 models. Audi redesigned the crankcase pressure regulating valve (PCV system) on top of the head and programmed the ECM different to reduce crankcase pressure during boost. Excessive pressure is what was forcing oil past the rings (in most cases) and also into the intake system. On a side note, excessive oil vapor in the intake system also causes quicker build up of carbon (actually oil deposits) on the intake valves of direct injected engines and since there's no fuel spraying on the valve, nothing to keep the deposits at bay.

 

Carbon also builds up on the tips of the injectors, but the carbon will buildup regardless of the oil consumption problem. Thats why the CDMA, 2013 2.0TFSI has a cold start / intake injector

 

Forgot about that one. Thanks Audi Tek. I'm not an Audi tech anymore (since May 31st) and a lot of data is getting lost in the ol' brain already.

 

Thanks for the helpful replies since I last posted in May. I took my car to the local Audi dealership in Exeter and they were incredibly helpful. Even though the warranty ended in March, it was not a problem. The service manager knew about the oil problem with these engines and that Audi would fix it free of charge despite being post warranty. It was then booked in for the first fix. The oil light didn't come on during the test period and I decided not to even look at the oil levels during that time as I found the electronic thing inconsistent anyway.

When it went back to have its oil weighed, Audi decided it was still burning too much oil and booked it in there and then for the second fix - new pistons etc. It's in there now having this done and I've just called the garage to check everything is ok as it was due back today. The service manager said there is more damage on the crankshaft shell (?) than anticipated, so that is also being replaced as part of the job.

I'm so impressed with the level of service I've had from Audi Exeter, they have been amazing! They have definitely restored my confidence in the Audi brand and I will happily replace this Audi with another one when the time comes.

Thanks to people on this forum too for helping me get to grips with the problem and how to tackle it!
