Hi
X5 e70 2009 335d auto
I keep getting the code 009c7b ac front / front klimaanlage Unknown failure I think everything is working ok any ideas please
Thanks

Interior temperature sensor fan faulty.  Sounds to me like something in the dash that checks the interior temp isn't happy.  Could be dusty?

Ok thanks for the reply will take filters and seniors out and clean them
