E70 Diesel Pre-Purchase Tips

[RuskiE39]

Hey Everyone,

Been searching a long time now for an E70 diesel and finally found a few local to me that i'm keeping my eyes on. Test drove one of them so far and really enjoyed it but need to know what are some things to look for and things to stay away from.

I've had many BMW's in my past, some diesel trucks, so i'm very capable and willing to wrench on and do repairs/maintenance.

My preferences are 2010-1012, black interior, STOCK, PNW cars (no rust), sub 150k miles. However, how many miles are too many before I should really start to worry about injectors, emissions crap, and turbos failing? I plan to delete and tune once the maintenance is caught up and or emissions components start to fail.

Transmissions seem to be solid on these AFAIK, anything I should know about?
Transfer case issues?
Seen some issues on timing chain failure?

Appreciate any input.

Thanks,
