The code you have is actually 25b not 256. It is the Footwell/Defrost Flap Servo Motor. The following links will give you the info you need to convert climatronic fault codes and look up the meaning. Hope this helps.

If you can just live with it. If not this will give you an idea of what is involved to gain access.



It is #28 in the diagram below. You might want to stand on your head and see if maybe just maybe you can access it from the footwell on the drivers side. Got a kid with small hands?
