Re: Oil light coming on occasionally with hard use: A4 B6
There's a recall on some 1.8T's because of a sludge problem.
Also the standard filter has been superseded with a larger unit.
Visit your Dealer ASAP.

Re: Oil light coming on occasionally with hard use: A4 B6
Thanks to everyone for your advice. I took it to Audi yesterday. I'll take
it back on Monday when they can look at it and I can drop it off. At first
they tried to tell me that the previous owner was 1000 miles late on the
first oil change and a few k on the next. I talked to them about the change
in oil, filter and interval spec from the original manual. Near the end of
the conversation the Assistant Service Mgr surprised me by bringing up the
possibility of putting in a new engine depending on the condition of the
engine. Are there any measurements or computer codes that would indicate the
engine needs to be replaced? I'd like to know this so that I can fight for
one if it is warranted.
Just out of curiosity, does anyone know why many syn 5w30 oils are in the
spec, but the M1 is not? Is it that the 0w40 spec is better and other brands
don't make 0w40?

Not to my knowledge. I guess if the dealer decides that the amount of work
involved in cleaning up the engine is too much or if they would not be able
to effectively remove all the sludge, then they may choose to put in another
engine, most likely a rebuilt one. If the oil flow was severely restricted,
then your turbo may be damaged as well due to lack of proper lubrication.
Make sure they check that too and replace if needed.

Generally it has to do with how well an oil is formulated to withstand
longer oil change intervals and still stay in grade. Some 5w-30 oils may
have never been tested against that VW spec. Most oils meeting the ACEA A3
spec (european oil agency) also meet the VW 502.00 spec.
Honestly, even though M1 5w-30 doesn't meet the spec on paper, the used oil
analyses of it I've seen after 10K miles in 1.8T engines look better than
those of M1 0w-40. But, just to cover your butt and not give any reason for
AoA to deny warranty, you should choose an oil that does meet that VW spec.
As you've seen from the link provided by Ian S, there are plenty to choose
from. And there are more, which aren't on that list, like Amsoil 5w-40 or
Motul Ester E-tech 0w-40.
I'm running Castrol SLX 0w-30 in my 1.8T. It's known as Castrol Syntec in
the US, but only if it says "Made in Germany" on the back label. If it says
"Made in USA", then it's not the same oil.
Good luck!
Pete

engine, most likely a rebuilt one. If the oil flow was severely restricted,
then your turbo may be damaged as well due to lack of proper lubrication.
Make sure they check that too and replace if needed.

Generally it has to do with how well an oil is formulated to withstand
longer oil change intervals and still stay in grade. Some 5w-30 oils may
have never been tested against that VW spec. Most oils meeting the ACEA A3
spec (european oil agency) also meet the VW 502.00 spec.
Honestly, even though M1 5w-30 doesn't meet the spec on paper, the used oil
analyses of it I've seen after 10K miles in 1.8T engines look better than
those of M1 0w-40. But, just to cover your butt and not give any reason for
AoA to deny warranty, you should choose an oil that does meet that VW spec.
As you've seen from the link provided by Ian S, there are plenty to choose
from. And there are more, which aren't on that list, like Amsoil 5w-40 or
Motul Ester E-tech 0w-40.
I'm running Castrol SLX 0w-30 in my 1.8T. It's known as Castrol Syntec in
the US, but only if it says "Made in Germany" on the back label. If it says
"Made in USA", then it's not the same oil.
Good luck!

Not to my knowledge. I guess if the dealer decides that the amount of work
involved in cleaning up the engine is too much or if they would not be able
to effectively remove all the sludge, then they may choose to put in another
engine, most likely a rebuilt one. If the oil flow was severely restricted,
then your turbo may be damaged as well due to lack of proper lubrication.

Re: Oil light coming on occasionally with hard use: A4 B6 - Update
So their diagnosis:
"Oil lamp coming on. Performed oil pressure test. Veh had sufficient PSI.
Ran veh & found oil level sensor inop intermit after veh gets hot. Replaced
oil level sensor & changed oil. Oil was dirty & need replacing along with
new filter." (Mileage: 39937)
Oil had been changed 1900 miles / 2 weeks before. A malfunctioning sensor
seems inconsistent with what happened as described in the quoted text below.
They didn't do anything to clean the engine.
They want me to come back in 2,000 miles for my 40K service and another oil
change.
Sounds like the run around to me.
Records indicate the following related to oil (Audi dealer service except
where noted):
11610 miles --- 10K service (oil change)18769 miles --- Audi service but no
oil change
24081 miles --- 20K service (oil change, 12471 miles since last) OIL PUMP
CHANGED
Oil light had come on
(2004 Aug - AUDI Oil sludge letter)
34535 miles --- 30K service (oil change, 10454 miles since last)
Oil light had come on
38081 miles --- I changed oil
Oil light had come on
39940 miles --- Oil change. Replaced oil level sensor
Oil light had come on
Any more advice?
Angry customer,
