When I fill up the fuel gauge still reads mid way between three quarter and full, is this the norm or should I try to get it fixed?

It makes it a little difficult to judge how low to run the tank safely.

Glad it's not just me <img src="/forums/images/graemlins/tongue.gif" alt="" /> <img src="/forums/images/graemlins/laugh.gif" alt="" />

I can get mine to 90-95% by risking an over-fill by doing the petrol-pump toe-curl squeeze!

i.e. the tank cut off stops the pump but I continue to squeeze the trigger, whilst waiting to get a petrol shower when the tank overflows, all the while curling my toes in hope it may actually have some karmic effect on my luck

7/8 Full is max I have achieved. On a run ~200miles then a refill seems ok.
Our +4 was just the same <img src="/forums/images/graemlins/thumbsup.gif" alt="" />

What is the potential for damage to the BMW hi tec fuel system if I run out of petrol? I would like to do it just once so that I know how far I can run on a tank full. <img src="/forums/images/graemlins/confused.gif" alt="" />

None.

Any sediment will be caught by the fuel filter and in all honesty, in such a new car (and with our quality of fuel), it will be fine.

The engine management software won't let the engine be damaged by fuel starvation.

Hmm, you're probably right but I have never liked the idea of running out of fuel. No matter how careful you are there is always a certain amount of sludge in the bottom of a tank, which might just get through. A safer way may be to empty the tank at a specific mark on the gauge and measure the amount of fuel that comes out?

I thought I heard the fuel pump was lubricated by the petrol and could be damaged but I may have dreamt it.

While I agree with Chris that you don't want to tempt fate, I equally believe you need to consider how many people run out of fuel on a daily basis. I, for one, managed to run my X5 dry <img src="/forums/images/graemlins/blush.gif" alt="" /> ... (it's a long story) and the engine was fine. If running the car dry was an engine killer, you'd be hearing about a fair few engine rebuilds, etc.

Most modern cars are designed to be idiot proof - my X5 experience being a good example of why <img src="/forums/images/graemlins/wink.gif" alt="" /> - and I'm sure designers take these 'human failures' into account when setting the systems up.

(As a side note - my RR actually closes the fuel filler pipe if you try to insert a petrol (rather than diesel) nozzle... you then have to manually reset the filler pipe to allow you to fill the car. Another example of idiot proofing design)
