Ciao Courage,before to admit to change somethings try to clean (with the auxile of OBD software) the errors wrote on the ECU, should be a reason of strange behaviours of electric/electronic parts, should be! Ask this on the service where you will go or also in external services that use bosch devices (i already made once, and i saw, and cleaned, a lot of errors related up and down of windows, lights, filters, ecc. ecc.) Marco p.s. i'm italian and i wrote in english 'cause i think that writing with my romanian you don't understand nothing :blink:
