Hi all, noticed these 2 errors whilst doing a routine scan

U0556-00 State: Permanent
Invalid data received from front display interface module - No sub type information

B105A-71 State: Permanent
Passenger compartment temperature sensor fan - actuator stuck

I have searched through the WM but cannot find the specific codes. I can think that could possibly be related but I have no idea what U0556 refers to and I cannot determine which sensor B105A refers to other than ATCM.

Does anybody have any ideas? If you have any knowledge or experience of these codes are they likely DIY jobs to fix or are they a major ball ache? _______________________________________________
