Can someone explain why the "Calibration File" in EPS shows always a "?" ?

I've already reflashed the "EPS" using "replace" and recalibrated it.

All modules are up to date.

The updates was smooth without problems with vnci?

Yes, everything went smoothly.

The "?" has always been there in SIPS, as long as I've had the car and SIPS installed, even after the workshop / Car Dealer performed updates.
In the view where you can break down the modules individually, all modules are up to date.

I think maybe this module doesn't need that part of update.

Very interesting thread. I have a problem with my AC not working (09/203 Luxury with heat pump). The thing is completely dead so no sounds /signs of it running at all. The battery heating over the app works. So I suspect it uses the PTC heater (because while it was heating up there were no sounds coming from the heat pump). The shop told me they have no clue what's wrong and that they read the DTC. So I guess they haven't found anything there. I personally think it's a software issue with the ecu and therefore have bought the VNCI adapter with 2 other guys.

1. What is the most recent software for the heat pump ecu?
2. What would you recommend doing if there is not DTC? I would at first do an IOC test where I try to force the heater to come on. If that doesn't work I would do a refresh of the ecu. Then update it and the last option would be the "replacement option" in SIPS.
3. If that doesn't work what else could the issue be (in terms of Software/what could fix it or should I try)?

Thanks in advance!
