Sorry to hear about your turbos phil? What happened? How long did it take to replace/source them? Did new OEM turbos come with the newer wastegate arms?
I'm asking so many questions because in the back of my mind I'm pretty sure at some-point I'll have to do the same with my car..luckily the garage that did most of my mods have done turbos on a 330d before so have some experience, just trying to work out how much to put aside for the worst case scenario
