Arrived home with 3/4 of a tank of juice, went in got gym gear.
40 mins later go to drive out of garage and notice gauge behind empty, Range was at 270kms and started dropping 1km per second when driving! Anybody experienced this before?

Appreciate the update.
Even though nobody could help, thanks for the diagnosis.. it will help someone else down the road.

I just started a thread like this as well. My gauge isn't reaching the 'full' mark. . .

 

[Gibo993]

I'm Sure mine is broken too

I fill up the car drive it 150 miles and it tells me its empty again!!! Not sure whats wrong but I have the bank manager looking into the problem for me.

 

[Dave321]

Warranty covered it, bill would have been €780!

Apparently the tanks sits over the back axle and has two pumps one feeds onside and pumps it over to the other then up to the engine, very complicated, and from what I heard its not good to run with low fuel as one pump will shut off and this can cause problems.

How hard is it to NOT run an M5 on low fuel

Thsi information needs to be taken on face value as the guy who tried to explain it to me can BS a little so would be good if someone can confirm.

true that there are two pumps, it is not good to run any car low on fuel as the fuel lubricates the pump.
I read in the handbook that performance may be reduced in the last 20-30 miles on range?!

Agree on how hard it is not to run tehm low on fuel!!!

Not sure if the level sensor is part of the pump or if it is seperate?!

 

[Hasan Shaikh]

The level sensor is part of the pump. And it is very common for the fuel level sensors to malfunction.

It is always advised not to let the fuel level drop below 1/4.

 

[Feld1128]

That means stopping for gas every other day:eek7:. What were they thinking 14 mpg and 16 gal fuel tank.

 

[Hasan Shaikh]

Indeed!

It pisses me off as well.
