The following scenario , Citan from 2015 is led at Reno under Kangoo II FW08 , is without rear windows and rear wiper . My customer would like to have but with . Have donors with all the necessary parts such as wiper switches and doors with windows and wiper . The cable laying on the plug to the rear door is identical . So everything is converted and nothing goes . Heater works , rear wiper does not . The fuse is available and it is also power on . In the configuration of the UCH is d He tail wiper not listed individually. For both cars not. I plug the UCH from the dispenser runs the wiper. With the Renolink software I can access the tail wiper and also put packets. When switching on you hear the relay click, but the wiper does not run. When driving directly with Renolink the same, but only click no wiper. Trying to pull the automatic configuratoion over the Reno server from the donor to the UCH remains also unsuccessful. A reprogramming of the UCH fails because probably the data are not stored. Jemdand an idea? Can those at Benz grab there and put “hacks “?
