Next weekend I'm going to change my 16th window regulator (multiple cars, 7x on the e53) . I can't take it anymore! Once it is fixed, I'll likely sell my e53. I don't seen any posts related to window regulator failure on the e70. Can someone please confirm they fixed the design on the e70? Does anyone know if BMW fixed the design on the 3 series and if so, when? Thanks.
