Hmmm. This can not be a fuse in my opinion. Heating requested remains 0% all the time.
Cooling/airco is working.
no more heating. Why would the car not request heating anymore ?

Mine also states 0% requested but my heat works fine. I'm thinking the heating requested is for the ESS heater. Sounds like the heater circuit is open-maybe the fuse or the heater coil itself.

thanks !
any idea where would the fuse for the heater be located ?

The fuse box is located in the face of the dash by the passenger door. At least in a US 2.5. The Owners manual has a diagram of the fuses and what each is for. Looks like there are maybe three fuses altogether that are associated with the heater.

When my heater went out three years ago (fortunately while under warranty), it was the "400V controller assembly". Here is a snip from the repair order:

it was indeed the 400v controller.
I'm now waiting in the SeC whilst they are replacing it ... hoping on goodwill

edit :
no goodwill unfortunately - the controller was already replaced in sep '14 which is unfortunately more then a year ago.
so replacement costs 900 euro + tax
