Hi Forum,

Short update: today, 8 days and ~900 km's after the message appeared, it disappeared again. I did visit the dealer (the car is 1.5 months out of warranty) who used Dice/Vadis: there was an intermittent DEM-xxxx error (forgot to write down the exact number) indicating that the Haldex AWD pump had operated outside its lower current threshold. The error was cleared. In addition, the unit was recalibrated again which should set the lower/upper current limits for the pump.
So, for now the problem is gone, however, it is not a given that recalibrating is all it takes. For sure it is the logical first step. Fingers crossed.

As per the dealer, there is no need to replace AWD oil or filter ever.

I wonder though what logic the car uses to remove the error message from the display, e.g. did the under current situation happens once and after 8 days / 900 km it decided to remove the message or?
