Hi all,
I have a 2004 ML270.
When I bought it it had an issue that it only blew hot air no matter how you change the dial.

After doing some research I understood it is the door blend actuator. Got a quote from Mercedes Bristol at £260 for the part.

I have Xentri diagnostics, so decided to double check before I buy a new one and spend the money.

What I find weird is the list of fault codes I got (see picture attached)
Considering all positioning motors are coming up as a fault I’m starting to think is it really the motor or could it be a wiring fault?
Has anyone else encountered something similar?
