I dont know about engine damage. Maybe the pump might get damage if you crank it a lot after running out of fuel... I dont recall anything in the 335d manual about what to do after running out of fuel, but I could have missed it.
I finally got paid today and took the check to the bank. I hit my reserve on the way home. My check should clear the bank in the morning and so my first stop is the bank auto teller and then a gas station with diesel. Next, Starbucks and maybe this frickin caffein deficit headache will go away. Sucks running out of money, that blue ray drive I bought turned out to be a big mistake.
I would venture to guess running totally out of fuel is a major concern for any direct injected engine regardless of fuel type since the HPFP are similar.
Pretty much everything DI has an in-tank lift pump these days to help keep the HPFP primed.
