[Biturbos4] How does the 'service in xxxx miles' work ?

This is what I have down in my VAG notes:
Module	Channel	Was	New	Description
17	43	10	4	Max oil change 4k miles

In VAG-com, go to module 17, channel 43 and the value will be 10; the oil
change light will turn on 10k miles after having been reset (I changed mine to
4k miles. Elsewhere, there's a count down that indicates how many miles it was
since the reset was done (usually by the dealer). When I was researching all
this a month or two back, my notes of the last dealer service were spot on with
the count down channel. Crappy dealer didn't reset anything this time - they
were busy damaging my wheels on their 'test drive'.

This isn't your answer, but it's the only thing I have documented. I know there
are additional indicators for months until service, months since service, miles
till service, miles since service, months until oil change, and months since
oil change. They were all accurate on mine but it sounds like yours are screwed
up. Maybe this will get you going in the right direction but if it doesn't, let
me know and I will dig up all the details.
P.S. There's a 'miles till service' display if you do something to the left
knob that sticks out of the instrument panel. I think that's what Keman said,
but I never had to do all that crap with key and/or the right knob.
