Thanks Tony,

I am bringing it in tonight. I will have them scan the ECU (I think
that is what it is referred to) to get the code (since the MIL is
illuminated there should be a problem code associated with this). I
will also mention checking the Waste Gate Actuator.

Incidentally, I have never worked on cars (other than a 1980 Chevy
Citation) so a lot of the terms that are used are a little foreign to
me.

Thanks for the tip.

Cheers

BTW - Turbo is shot - being replaced under extended engine warranty
(phew).

Now being told that the evaporator unit is acting up - what is this and
what does this mean? Can it be related to the Oil Sludge problem that
was supposed to be fixed last week?

What are these "chips" you mentioned. I am assuming this is an
"aftermarket" part - in this cased something to do withthe on-board
computer system that flashes the system and removes some of the
restrictions the stock system puts on the engine. How do I go about
looking into this and are there any good online resources?

Thanks

You are lucky that the warranty covers it.

Evaporator is a component in the air conditioning system that cools the interior
air when the gas evaporates. It is located in the area below the windshield. Not
related to the sludge issue. Still the condenser part of the system is loosened
and swung down under the engine when major work is performed on the engine. Any
stress on the AC components risks causing a leak but not likely where they are
claiming. They are probably looking at an AC oil leak at a joint in the system.
Ask them to test with a 'sniffer' to confirm the problem. I would be suspicious
that they are just looking to get more $$$ from you to cover some of the
warranty costs.

Chips: various after-market performance parts companies sell chips that replace
the stock ones in the ECU. They reverse engineer the factory algorithm than
controls boost level, fuel mapping and ignition timing to optimize various
things including hp / torque. The stock chips are rather conservative and an
after market one can make a very impressive difference.

My chip is rated at one bar which increases boost from 7 - 10 up to 15 - 18. It
is available from APR performance parts.

If you are thinking of this you need to realize that it will void the remainder
of you warranty but will increase your enjoyment. Decisions. Decisions...

Thanks for the info Tony.

Interesting story on the Warranty. When I purchased the car I was told
that the 1.8T engines have a problem with oil sludge but the engine was
to be covered by an 8 year warranty (i.e. on an '02 this would take the
warranty period to 2010). To me this sounded great. I did not
anticipate any problems and my mechanic said the car seemed in great
shape (obviously didn't look into the engine). About 200KMs into my
ownership of the car - it died - oil sludge.

Downside - I did not have the service records for the vehicle. Upside
was that the local Audi dealer/service center provided this information
and certified it in the Service Manual. Downside is that the previous
owner lapsed a few thousand kilometers on a couple of oil changes and
Audi was not honoring the warranty (initially) - after some heated
discussion and a very useless call to Audi Customer Advocacy center
(HAHAHAHA), VAG is now covering the car under the warranty. I would
have been screwed if they did not.

The turbo should be done by today.

This vap thing sounds a little fishy to me and I do wonder if it is the
center trying to recoup some margin off me since all of the work done
on my car to date is under warranty.

I may consider a mod chip in the future but at this point I want to
keep the warranty intact. It sounds like I will need it!

Cheers
