I provided the SA with SIB number for my 535i auto-sport tranny thump and lurch problems, but no go. The SA can only fix problem that replicateable at the dealer period. Not sure the logic, must be a good reason by BMWNA. I wonder why is it so hard to check the S/W version on the car. I am in the S/W business and everytime we release S/W to fix bugs on the field it has different part number from the last buggy one, why can't BMW do this?
