I am a bit confused as the OP has a 2013 TFSI engine and these are the upgraded engines. The faulty engines that consumed oil were only 2008 to 2011.
Audi are still offering these repairs if you unlucky enough to own one.
My work colleague has a 2010 TFSI from new with Audi service and they doing the repairs free. Some members here mentioned they had no Audi service history but Audi repaired the engine if owner made 10% contribution.
These faulty engines had 3 stage repairs.
Stage 1..upgrade the PCV
Stage 2..upgrade piston and rings
Stage 3..complete engine replace.
I bought a scary 2009 model in Oct. Done a oil change and been monitoring nervously. So far done about 550miles due to lockdown and its been stable 1 bar below the max for last 400 miles. From what I googled as I am in same boat, after the engine repaired owners reporting consumption between 2k to 4k between top up.
Before the repair it was only couple hundred miles
What is the problem? The early version of the TFSI gasoline engines found in the A5, A4 and Q5 have an inherent design fault which leads to high consumption of oil. The base problem seems to relate to the piston rings, which allow small amounts of oil to leak roundcasestudies.atlanticmotorcar.com
Yep me too (confused). Trawling different forums it can be difficult to see if cars are pre-2013 or what size engine (people don't always say).
Agree lots of reports pre-2013 engines. Less (but not none) post-2013.
I found this thread in Audi world - Audi A4 b8.5 (2013) excessive oil consumption - AudiWorld Forums
Possibly the issue was not fully fixed in 2013, or the fix didn't kick in until later in 2013? I'm not sure.
I'm hoping PCV repair might do it?
Its a difficult one. Given the last owner of Greggs car - and the cosmetic condition he bought it in, i think the last owner just lived with it and didn't see it as a problem?
Be interesting to know how many miles the last owner did per year of ownership? Could work out oil consumption and whether they would have noticed it (i.e 3000 miles per year, 3 oil top ups, some owners wont see that as an issue).
I am casting here though. Wish i knew more...
