Yea I'm actually with you 100%. Let me know if any line works out. I'll try later as well.

It would be helpful if we knew what the code for those lights were. Like fl/al/Sv/. Etc

Wait...are you saying that your IHKA control panel doesn't have the MAX button...but the REST button only?

If your IHKA only has the REST button...then it does NOT have the MAX cooling feature. You'd need to install an IHKA with the MAX button, then code it to your car.

Qsilver, very interesting information. My IHKA has only the REST and I tried today on my way home the there is no MAX function on it.
I tried a while back to use the main-board from a module that had the MAX function but the screen was broken. Unfortunately I couldn't make one new module. My screen board wasn't compatible with the main board from the spare module.

I had no idea there was even a solar sensor... Very complex engineering in these cars.
So, without the solar sensor I guess I can get the MAX function but the IHKA will not compensate for solar radiation.

I cannot find this:

Coolant Damping
KUEHLWASSER_DEDAEMPFUNG - default is 25_sekunden

Slick, where did you find it?

FM, what are the last 7 digits of your VIN? or, at least, what is the month/year of production?

your car is actually equipped with IHKR, not IHKA - i am still checking what the difference is between the two... IHKR was fitted from 1999-09 to 2000-09

Are you sure it's IHKR? It looks like the IHKR refers to the manual climate control.
