Hi guys I have one here but ends in C not D, this came from a 2010 T5.1 caravelle exec with full electric sliding doors and was working fine when removed. I am trying to work out if it is needed or the smaller one to add power latching tailgate and passenger sliding door to my van. If it’s not needed then it will be for sale and I will not be asking £200 for it and it can be tried before making payment if that helps either of you out?
