RNS E Issue-
I have seen this before.
pin 31 and pin 3 are your options.
(FYI - pin #31 MUST be used when you have a 2002+ allroad...as pin#3 is tied into the height leveling system..and there have been reports of other who have "overloaded" pin#3 and it led to some malfunctions in the height system etc).
Good luck!
