Hi Guys and Gals,

Just purchased a 2009 A4 wagon 195,000kms- nice car great gas mileage - but yup uses a crazy amount of oil. 1 quart per 300ish kms.

Bought off private sale so no dealer to talk to.

I am getting the new pcv valve and installing it myself this week.

The common areas for consumption are PCV- Rings - valve seals - and possible turbo bearings seals.

Here is something I have noticed - after 30mins of driving I have noticed some smoke coming out the tail pipes on acceleration/ take off only. Or if I put the gas to the floor on the highway.

It will not do this when the engine is cold only after 20-30 mins? Very strange and I can not figure it out.

Can someone send me some pointers on where to look. Before I bit the bullet and take it to my local Audi stealer.

Thanks alot
Nik

 

Usually on normal acceleration if you blow oil (slight steady stream) then the rings are bad. If it is valve guides you will see a PUFF of smoke after you hit the gas after coasting like going down a hill. Have a compression and leak test done to see where the problem is.

 

Thanks - My dealership has ordered me an updated PVC - should have it installed this weekend -
Will update - thanks again
Nik

 

Sounds like the dreaded rings & pistons syndrome. I would contact Audi and see what they will do for you. Excessive oil usage on 2009-2010 2LTR motors is a known issue. Good Luck
