'07 A3 2.0t Oil Consumption

[Andrée-Anne Bourgeois]

Two comments :

1- An heavy foot will consume more oil. That's just the way it is with a
turbo engine (IME).

2- Some cars are more prone to oil consumption, especially in city driving
where the oil separator device can not reach operating temperature or vacuum
is too strong or something else. I don't know the exact reason, but this was
a problem when I was at Renault, and it is a known problem on the Saab 2.3
engine that we own.

More, some oils are more prone to vaporize, so this augment the preceding
sentences.

We have this heavy oil consumption here in cold Montreal, it's just a fact.
Madame don’t have the same problem, but when I drive her car for a period of
time, oil consumption augment significantly. Her car is a turbo Saab. My
1983 urQuattro with a freshly rebuilt turbo engine drinks oil when I take
her to a lapping session (at the ice racing track) but is otherwise totally
normal. 

But every now and then, the press cars I drive are low on oil, even if they
are always new cars. I justify this on the driving style of the other
journalists, (not mine, obviously...:-)) hence my conclusions above. The
last one that blipped the oil light was a 2009 535xi, a six cylinder turbo
engine with less than 10 000 miles.

About valve tapping, are you sure it is valve noise ? These 2.0T produce
much noise from the injectors, specially the direct injection newer
versions. Valve tap noise should clear after a few seconds, unless there is
a mechanical problem

Howdy,

Is there any sort of established "normal" oil consumption for the 2.0t
engine on my 2007 A3 (USA)?

On a couple of occasions since I have owned it, I have gotten the oil
light on the dash, have quickly stopped, and found that the dipstick
was reading less than "min".  On both occasions I have topped off with
about 1 quart of oil to rectify the situation.

I had a scheduled maintenance at 23,251 miles on 10/9/2009 where I
expressed my concerns to the service advisor who indicated that this
was not a problem.

I'm not sure I'm convinced only because I have owned many cars from
many manufacturers and have never had oil consumption this noticeable.

The current example would be I just now added 1 quart after driving
4,000 miles since my service appointment on 10/9/2009 when I was told
it was not abnormal.

Even my crappy 1983 Pontiac Bonneville didn't burn that much oil
(granted it DID have a myriad of other issues)

Coolant appears clean and oil shows no sign of being contaminated w
coolant.  I have noticed zero oil spots in my parking space.  MPG has
not changed one way or the other since I bought it

I think this is normal, but what sounds like valve tapping has been
pretty noticeable on this engine since new.  I had the same noises on
my 2003 GTI with the 1.8t (but no oil consumption issues)

Comments and suggestions welcome.

Thanks!
