Well I'm now back after a dreaded stint away from the four rings....And picking up a 3.0TDI coupe in a weeks time and cant wait. Unfortunately I need to fit a detachable towbar and electrics so I can carry my bikes..... I am happy about fitting the towbar and electrics but cant find any info (even with a search) what codings I need to change once I've installed the electrics. Can anyone help...... Thanks in advance guys.
