2008 535 Waste Gate Rattle
So, I have read some little pieces of information regarding the turbo Waste Gate rattle. Mine is unbearable with my windows open, which is unfortunate because the weather outside is beautiful right now!
I've already had the HPFP replaced at least twice, after replacing my spark plugs and all the fuel injectors over the last 2 years. So this is just the latest disappointment in my owning a $60,000 imported vehicle. I think it's sad that you know your service advisor and all of the rental employees by name.
My several service advisers have been very nice and do whatever BMW NA tells them to do, so I can't blame them. This is obviously another case of poor design and then denial that any such problem exists.
According to TID SI B11 13 07 (given to me by my SA), 'This slight rattle noise is considered normal operation of the mechanical waste gate valve. No repair should be attempted for this type of rattling complaint.' Way to go BMW. Do not fix the hardware, pacify the customer with a BS software update.
Has anyone had success with an actual repair for this ridiculous condition?
