Hello, I still make mistakes, until then: is something known that the leather steering wheel heats better with heating times and sometimes less intensely? I even feel that it sometimes gets differently from sector to sector. And it hardly heated at low outside temperature, at few degrees more strangely good. But felt three-quarters of the heating processes bad. And then IMHO does not change during the course of the ride or at / on. That is the current condition. I have to also make RTFM again, but assume that there could be a contact matter? Thanks and greetings edit: have just found the PDFs to the schematic of the Phaeton of @gusto-V10 aka Günther, is incredible, viieelen Thank you
