Did you ever wonder why your turbo seized? How do you treat your car? Do you let it warm up before driving, and let it idle down before shutting off?(doing so allows turbo to unspool, and saves alot of ware and tear) Just a thought....my 85 300D has always been warmed up to operating temperature and let idle down, and doesn't usually get shut off if i'm going to be somewhere for over a few hours. I found that this saves ware on the entire car, for christ sake, It's a diesel, you don't have to shut it off!
