2.0TFSI Oil Consumption

[jimmyVX]

I have fairly recently bought a 2011 B8 A4 that had 35k on the clock. It is now just under 38k miles and in that time I have put in just under 3ltrs of oil. This really seems excessive to my eyes but have read that modern petrol engines do use some oil. My car is booking in with Audi on Thursday to have a rattle fixed under warranty and to start an oil consumption trial.

I know there are many threads on this out there, but just curious to know, what 'fixes' have been offered to improve high oil consumption levels and what I need to be pushing for?

Thanks for the above replies.

I will have to see what the outcome is at the end of the week. It just feels excessive im my eyes as I am roughly topping up a litre of oil every 3 petrol fill ups, its going to cost a fortune in the long run!

Well car dropped off at the dealer this morning after completing the 600 mile (1000km) oil consumption trial. I checked the level on the computer before I left and it had dropped from full to just below 1/4 in that time, which from experience is around 0.7/0.8ltr. Hopefully they deem this to be on the high side and look to complete some remedial work.

To be honest I am not entirely sure, I collected the car very late in the day and only the one service assistant was around and he didnt know exactly what was carried out. The software I think has had an update as the oil level screen gave a message stating that an accurate level could only be found once the engine was warm which I had never seen before.

Well they have confirmed that new pistons and rods will be replaced along with various other parts all under warranty. They will give me a parts breakdown once completed. Sounds like quite an involved task and I am just glad I have warranty cover.

Does anyone know why the pistons and rods are being replaced, I assume this is due to a design change?

Just a question, are there any other 'while you are there' jobs that I should get done at the same time while the engine is open?

My car is now on 35k miles so a bit beyond the 20k previously mentioned. I am amazed that the previous owner didnt do anything about it. I will try to find out the cost of the work from the dealer once it has been completed in a couple of week time and report back.

It was p/x at the supplying dealer at 2.5yrs old for basically the same car, otherwise I might have agreed with you.

My car booked in for the work on Monday.

Many thanks for explaining to me the reasoning behind the changing out of the pistons, makes sense. I will be sure to ask about the bores and see if they can provide some photos.

I think it will get the belt replaced while its there, seems to make sense. What kind of service interval is the aux belt and water pump on?
