Believe it or not, it is normal for these engines to use about a quart every 2000 even when they are essentially new. Note that I said, "use", not "burn". The combination of higher compression and operating temperatures causes oil to pass through the engine. You might notice your tail pipes have a good coating on the inside.
 
I managed to slow the process by converting to Mobil 1 0W40. I get much better performance and I only use a quart every 3500-4000.

Oil leaks?... by byronwalter

...I'm on Audi Number 3 (all A4s). I've had a couple of the 1.8t engines and currently have the 2 liter (reflashed ecu for > 230 hp), none of which have burned oil between my 5k mile oil changes. My somewhat worthless opinion is that one's break in practices have much to do with future oil burning.
 
On my car's for the first 1000 miles I've always focused on driving smoothly and avoidling constant rpm's and high torque. But I will let 'em rev up gently to near redline and back down.
 
But I have read of what might seem like a bit of an oil thirst on some of the eight cylinder 4.2FSI Audi engines
 
As for the Mk2 TT, you are correct that the same six cylinder engine is returning. Seems like a pretty nice unit which seems to work nicely in tight transverse engine layouts. But I do wish that Audi could fit the 3.1FSI engine in the new TT.
 
BTW, the TT board should start getting a little more active as we're only a few months away from the next gen TT in North America.

Switch to a 40 wt. by thunderchild1

I now use 40 wt oils and my oil consumption has dropped to nothing. It may be because I have broken the car in more but I have no more oil consumption. It will be 40 wt's for my car from now on.

Hi Mikey
I have a 02 225 TT and I was concerned about the oil light coming on during a road trip. When I took it Scottsdale Audi (AZ) I was told it is normal to use a qt about 1k miles or more. I looked it up in the car book and it does reflec the same. It is used to keep the turbo lube etc. I have nearly 63K on mine and have only put 2 qts in over 30k miles, not counting the reg oil changes. About the speed-o, never had that problem.

Oil pressure light coming on...among other things by dianebou

I am new Audi owner of a pre-owned 2001 TT Quattro (sedan). It's a manual 5-speed. I am experiencing several problems, the first (and most alarming) of which my mechanic has no solution for.
 
--The oil pressure warning light comes on intermittently, just about every time I drive the car. It seems to happen in a couple of different circumstances: a) When I am coming off the highway after being in 5th, and must come to a stop at the end of the ramp. Then, it will go off again when I move forward, but will come on again relentlessly every time I must come to a stop; b) when I encounter a lot of stop-and-go traffic and continually accelerate/decelerate.
 
In the 2nd instance, recently, I was driving in the city, in extremely heavy traffic, and the oil pressure light went on and off continuously. Not only that, but the engine started to overheat.
 
I have checked the oil, and the level seems fine. Also, I am using the highest quality synthetic oil available (according to my mechanic...I couldn't tell you what kind specifically).
 
Is this an oil pressure problem? How serious is it? (i.e., how expensive?) Thanks so much for your help!

Well you might have to install (temporarily) an analog oil gauge (one with numbers) to read what's going on, to make sure it's not just a loose wire grounding out. If the gauge drops every time you maneuver, then that is a bit troubling. Possibly you have some kind of blockage or malfunction to the oil pump pickup screen, or a broken baffle in the oil pan (that should keep the oil from sloshing around in there).
 
So I'd check for a loose wire or bad sensor first off, then screw in an analog gauge for testing.

One thing about Audi engines, you MUST use the OEM oil filters or exact equivalent to assure that you don't get funny lifter noises. Apparently, some off-brand oil filters aerate the oil, and the lifters tend to collapse.
 
Before digging into the engine by all means go buy an AUDI filter and the oil weight recommended in your owner's manual and see if this corrects your problem.

I think the V-6 is more susceptible to non-factory oil filters, from the reading I've been doing on the subject.
 
If the non factory oil filter is causing problem, you'd know it. The car would either run badly or not at all. It might not even start. One has to see a non-start Audi cured simply by replacing an oil filter to believe such a thing is possible, but I lost a bet with a mechanic on that very incident.
