Hello, and another question about the stand-up heating….. I had – like probably some others also – in my XC90 D5 the stand-up heating function released and then in the spring the AEM module with Comfort Call installed. It also worked everything, whereby the last “test run” (I just checked every few weeks if the SH works) is about 5 weeks ago and went successful. Today I could have the SH the first time needed, and there was unfortunately nothing at all. In answer (you call in principle his car……) I got only the message that the participant “temporarily not available” was. Then I expanded the SIM card and checked it in my mobile phone. Result: I could call and call. So the card and the connection are ok. Then I put the card back in place, the plug connection solved and fixed again (since the installation was unfortunately the first time that I put a hand on it). Result: There was a call sign (so no temporally not available), but it was not possible to get the answer to the question. So there was nothing else to do the same thing.
