Is it necessary to bleed an E90 320d if you run out of diesel?

[Tindo1]

Hello guys, my first post here. So I was driving from PMB to East London and somewhere around Kokstad I got a flashing message on my dash (stayed for like a second) saying I have no fuel. This seemed odd considering my gauge was showing me I still had more than a quarter tank. To cut long story short after hiking to town to get fuel, I read furiously at night and realised its an occasional problem on the E90s. I also learnt to check the exact fuel levels in both tanks using the hidden BC menus and I am at the moment waiting for my right tank to dry up so that I can see whether my gauge is dead or its the car that is incapable of getting fuel from the left tank. If its the second scenario, then I am going to run out of fuel again pretty soon as I do my bush diagnostics. What I need to know is how do I prime / bleed the air out of the fuel lines. I know from an old Landcruiser I used that I used that once you run out of fue[/quote]l there was a small lever you pumped too get rid of the airlock. Is there something similar on the BMW E90. Is there something I should be worried about or preventative measures I should be taking like maybe changing the diesel filter so that I wont issues in future?

You can "activate" the fuel pump by pressing the start key without your foot on the brake. As the cluster lights up, you should hear the pump humming.

Mechanics use this method to bleed the system, when installing new diesel filters, without specialist equipment. I am sure you can use the same method when you run out of diesel.

+1 Did this when I changed the filter on my diesel cars, works perfectly

I had a little heart attack today, my car also refused to start. The diesel was liw, however not empty. Had to fetch my wife at home, when we wanted to go the engine turned, would not start however. Got diesel, put it in, car refused to start. Called a mechanic who said that he would be with me momentarily. My neighbour suggested that I bleed the system, we looked but could not find a button as in older diesel cars with which to bleed. I became rather despondent, thinking of a small fortune that was about to be spent a week before my daughter is to be born. But then I googled the problem and came across this thread and then tried the method of bleeding as mentioned. It worked. Now I am only nervous due to the coming birth and not also because of a broken diesel BMW.
