The 4 fields for each channel - looks like you were in measuring blocks -8
instead of Adaptation - 10 ?

This looks like more detail...

http://www.audi-resource.com/ecu18.php and these are the adaptations for AUX HEATER.
Then you have to do adaptation on HVAC channel 16 to 001.

Now, I may have changed some on HVAC by mistake. eek.

There's a label file for the HVAC that you can download and add to VCDS in the user label file folder....How accurate etc it is, i don't know, but certainly a lot of the values seemed to be plausible when I had a play the other night and it makes some sense out of measuring blocks

Call the file the controllers number 4EO....lbl iirc

Thanks again Snap.
I didn't get home last night untill midnight so the day was wasted for thinking about the 8.
That link gives me something to puzzle at, wish these clever sods would write the info. in English that can be read and made sense of, or include a guide to help us simple folk.
I agree with you, channel 16 change to 1.
What about channel 07? Mine is at 0, while yours is at 1. Do you think that I should change mine to 1?
If the 8 had been a Ford it would have had an ON/OFF switch on the dash with a little light in it.

Sorry for confusing it even more with my dodgy old notes.
I'm still not 100% sure which of those were adaptations on HVAC and which on Aux heater. 16 is definately HVAC as I tested it on Sunday!

Maybe this mix up is why my rear heated seats no longer work?
Lesson is always keep a note of what you change (original values)

FINALLY!!! I've got heat!!!
Actually more important than just keeping warm (seats help) as it means you can clear your windows from moisture and icing!

When I swapped the valve the other day and didn't get much of a change, I ended up putting on the old pump, which i'd tested and it turned off a battery, but i don't know if it was weak.....Anyway I swapped it back to the one that i got with the "new" valve.

Also seeing as i needed to go back in as I had a bit of a coolant leak (loose pipe, bottom at the back, it seems), I decided I'd do a flush of the heater matrix's

Using a hose pipe coupler and a pair of jubliee clips on a couple of bits of hose I had meant i could connect a pump to a bucket of cleaner and run it through just the matrix. Top & Bottom back pipes. Left pair does drivers, right pair does passengers.

It would have been easy but my pond pump was too weak, the drill pump didn't want to work and my oil pump doesn't like water as it self lubricates, so was a little more fiddly than i'd like, But i ran cleaner (single bucket) through one, then the other, then clean water through each of them (dual bucket so it didn't mix, but flushed). Ideally you'd want to then pump coolant through, but i ran out of time and just added a strong mix once I filled the system back up.

Interestingly each time I drain the coolant i get grit out the system!!!

I'll probably do another partial drain after Christmas as it's only a bolt on the bottom and filling with a bit of bleeding!
I've used Bilsten G13 coolant concentrate as it's the same spec pink/purple and its ~£30 for 5L from Amazon. Ok it's not "Audi" but the car is more a to be used car than precious!
