Just tell the stealership that this is no time for jokes and to get the new engine on order ASAP. Tell them you are glad that they realize that when replacing the engine, a new oil pump is also a great idea.So what if they call me on Tuesday and say "We changed the oil pump your car is ready to go"
I don't see how pieces of metal can come off an oil pump. I wish I knew what they were thinking. They should just give me the M6 they have with less miles and keep mine hahaPerhaps BMW is hoping the metal came from the oil pump? Sounds like a shot in the dark to try and avoid dishing out the $$$ for a new engine.
I am purchasingYou should contact BMW NA, if your car is on lease with BMW, tell them you will stop the payments and that you will leave the car and the keys at their HQ.
I had almost a year of BMW GB bullshitting me when my gearbox failed a few years ago on my M6, to date I never got an explanation of what the fault was, however they ended up replacing the car for me at their cost, which was OK by me.
