Yeah part number stamped on clip. TPS were aware of this and said the mk5 platform has 2 types of 12 pin clips, but could only remember this and only have 1 clip listed on their system and didnt want to commit without a part number. I think I shall order some mk4 r32 12 pin clips with this part number 1J0 941 185, they look right. Its a intresting one, I have found another mk5 owner with same problem however he never reported if he solved problem and how. My headlights only have a locking in tab on the 1 side (Wish I took pics now of the headlight clip bit)
