Some guidance please.  I have had to replace the combined Xenon headlight and driving/fog light unit on the near side of my 13 Yeti.  The new unit is an OEM one from the local dealer.  I swapped over the aluminium control unit and plus bulb holders etc. and reassembled everything.  It all works except for the Xenon headlight, and there seems to be no ‘sweep’ on start up from the other one that lights up.  All connections seem OK but if anyone could suggest how to diagnose the fault I would be very grateful.

Best bet would be to speak to the dealer who supplied the light unit and see if they'd be willing to help, or alternatively try to find a member local to you who has VCDS and get them to scan the car for you.
