Hello, since last week I bought an XC90 3.2 Summum MY2007, unfortunately some errors have occurred now…Since today the engine control light, in the error memory (read out with VIDA) are stored three errors, once errory software electric driver seat adjustment does not work, yellow then still stored air quality sensor internal error air conditioning without function, red stored temperature sensor internal error ambient air temperature check the Funkti On the outside mirror function limited…. red I found yesterday that the temperature sensor in the driver’s mirror (with BLIS) is defective, the cable is dead. Already ordered new. The normal outside temperature display in the instrument cluster seems to work properly. Furthermore, I found that the sound module/power amplifier only gives an output signal for the tweeters. Did anyone have such problems here? What is really broken? Where does the air quality sensor sit at m XC90?Like the S60 in the front under the wipers? Where is the outside temperature sensor for the instrument cluster, is this possibly defective? Please for help, this is my first XC90 with V70I and II,C70 I,V50 and S60 I know myself, had the cars already all or, I still have. Thanks for every post!!!
