2011 BMW 550I XDRIVE
Vacuum pump replaced at 41,00 miles
Vacuum pump replaced at 68,00 miles
Vacuum pump failed again at 99,000 miles
car has 2 year warranty on vacuum pump. so far i have 11 months left. dealer said they would replace again, then they call me and tell me the crankcase was starved for oil and that made the vacuum pump fail. i had just topped off with oil the same day, bmw even remembers me going to purchase a quart before going to the beach. there trying to see if my jb4 tune messed it up. Thats BS these issues happened before i put that on. they called a BMW Tech from LA to come and check it out today. they are going to decide if they should cover it or not. to dissassemble the crankcase cost 2,00 with 12 hours of work. i have not gave them permission yet but the tech is coming today. if they try to deny based on tune what do i do? the fuel injectors and a bunch of sensors have also failed before. look at the previous post before this
