Just dropped $4600 to fix the coolant problem and have the engine gaskets replaced...FML someone please post a BMW horror story to make me feel better!
residue? That doesn't mean squat! 4600 dollars is no small sum of money. I had the same repair done after a tech changing the transmission pan notice a dribble of fluid on top of the transmission housing. They pressure tested it to a bad valley pan gasket and warranty/inspector saw the dribble and paid for it.It's actually super comprehensive but anything over so much $ they send out an inspector and I guess he seen residue at the bottom of some tank
