Ive got one here in my hand and it clicks when i move it off of zero!! I have an issue where the switch on the right does the seat on the left and visa versa Also had an issue with the passenger seat where the element had broken! they can be repaired or as i did, get a new heat pad from vw and get your local trimmer to fit it as its not a long job! it took my mate about an hour to do that was from removal to refit!!
