A new one on me
 

Anyone ever get this fault before?

00715 - Rear footwell vent pos. motor locked or has no voltage supply

Didnt even know there was a rear footwell vent, I assume its one of the 8 or so flap motors under the dash?

I was aware of the rear footwell vents, having been hoking around under the seats, but didn't know of any motors. Never thought about the ones in the dash. A couple of mine have failed, but they normally give some indication of which one with an associated code like (G113).

I've read various threads about the D3 having problems with the motors though.
