Hello together, I am new here and also own a Phaeton V6 Tdi bj 2005 I have a problem with my SH. This has been delivered ex factory with stand heating function + remote control. Now unfortunately broken. I changed it for an same used one, because I unfortunately also have no access to the control unit. With my old one the control unit is completely destroyed by the water and could not read it anymore. My question is if I have to let them learn at VW ? Electricity is on and plugs + cables are ok. 3DO 815 005 AA is the component number. Thank you
