I think that it is reporting that you have several problems:
- Leaking gas filler cap or a problem with the evaporation control system
- Non functioning auto leveling headlight control
- low on oil or oil pressure

You should get the codes scanned to verify the problems.

Hi Dave:

no, it doesn't do that if I insert the key and turn ignition on but
don't start the engine - also if I then go back to the zero position
with key (not having the started the engine) I won't see this
behavior, i.e. I must have started the engine and turned it off again
(that error is repeatable every time).

My biggest hope is that someone else had the exact same problem...

Thanks, Harry.

Harry, Autozone stores (and probably some other brands) will scan the
codes for free and give you a nice printout of the results. You really
need to get the codes scanned before doing anything else, that's
really the only way to tell what's happening here.

Hi Dan:

thanks for the tip - I called a local repair station who would be able
to do that but - after explaining the situation - they indicated that
they wouldn't see any codes unless the check engine light was also
on... It's off in my case.

Cheerio, Harry.

Hi Dave:

no, the engine turns off immediately. Not sure whether I have a
"timer"!?

Cheerio, Harry.

A4 1.8T does not have a turbo timer unless added by the owner.

Your local repair shop is not correct about the codes. The car stored
them even without a CEL. Try another shop that is more familiar with Audis.

thanks - will do.

Small update: as magically as the problem surfaced it magically
disappeared again today (until the next rain I guess)... Will still
have the codes scanned at the next best opportunity.

If the cause is found I'll post an update to the list.

Thanks, Harry.

no, everything seems fine there. Best case it's just been the extreme
humidity associated with the recent rain... Let's see.

Thanks, Harry.

I don't get it - how did your car get so much water inside? I live in
an area that gets severe summer thunderstorms, with 50+mph winds and
torrential downpours. None of my Audis ever got wet inside, unless a
window was down!

I used to, before I had a garage. Even now, I park the cars under
trees in parking lots, etc.

I have always cleared the drains, even way back when before I owned
Audis - othe rmakes have this same set-up.

ISTR reading about it in an owner's manual.

Sunroofs have drains, too. Does everyone ignore those things, too? I
clean those out every couple of years - they collect dirt and clog as
well.

Sorry, but if folks think the only thing they need to do to a car is
put gas in and make the payments, then blame the manufacturer for not
idiot-proofing their cars...

E.P.

Yeah, a good service person should point it out. The owner's manual
should say that such things need to be done, if not how.

Sort of like an oil change.

I clean the cowl drains with my finger at every oil change, so I never
have had the problem. The sunroof drains I clean the first time I
vacuum the car in the spring (outside the garage).

I dunno - I'm have trouble working up concern for folks who don't do
this stuff. It's not a secret.

I have reported to the group before..... (search for WATER INGRESS A6) as I
have experienced similar MAJOR flooding with multiple consequences.
There is a drain "tube" hidden away under the battery. This gets blocked
with leaves etc, allows the chamber the battery is located in to fill with
water. It floods the wiper motor, fusebox & everything else within that
chamber, then water finds its way to the car interior via grommets where
cables pass from the interior of the car into engine compartment. Thence the
wiring loom gets saturated & crimped connectors with it get corroded. Not to
mention the risk to any control modules located in the footwells. . . .

Maybe you don't park your car near any trees Ed ?

Just my experience

One possible (and common) reason, blocked drain hole under the pollen
filter/battery.

Look at pictures from a Passat, but mostly the same with Audi.

Second, one of the doors doesn't fit - and need to be adjusted, or the
rubber sealing have to be replaced. Adjusting is quite easy to do.
