Good day together, with my master (III, year 2014) the windscreen wipers suddenly stopped in the field of view during the ride. I then tested it with a new fuse, a new wiper motor and a new wiper rod. In all cases, the fuse flies out directly with the wiper. Even when controlling the cables I could not see anything. Now a car mechanic told me that it could be good that the fault lies in the UPC and that the Now I come to my 2 questions: 1) Can the UPC simply be replaced, or does the new one have to be programmed/coded by a Renault workshop? 2) It’s not easy to come to a new UPC; an online shop told me that the spare parts for Renault come from Russia, and there are currently many deliveries stopped. Now I have found a used UPC online, but the part number of this used UPC shows at the end e The part number of my built-in: 284B67570R– (a picture I have linked) The part number of the used: 284B67570R–B If you are looking for the part number in general, there is always only “284B67570R” written there, but it is never the talk of this addition with the strokes. This addition can then only be found on the lid. Does anyone know what this addition means and whether I can also take the used UPC with the other addition? I bed anke me quite heartily for a feedback. Best regards Julian
