Also sounds like you were suffering fuel "slosh"

What the fek is fuel slosh, LD? lol

Ever put a pint of puke in a large basin and slipped it around?

Thats 'fuel slosh'.....        

Nicely put H21 - hope Webby understands ok

I presume you're talking about the shite that's been allowed to slosh round the engine due to the fuel going so low. If not, I aint got a fckuing clue what you're talking about 

Imagine the fuel tank is the large bowl, and the fuel is the puke.. as you drive around the fuel will move around the tank - since the 'pickup' of the pump is only in one place, all it takes is a hard corner et viola, you're sucking air (or, in the analogy, have puke down your shirt)..

Exactly as above. The main reason I suspect it in this instance is because he was going down a spiral when it cut out

As said though, worth checking the codes just in case

You're all barking up the wrong tree...  ...OP has clearly stated the cause

Well, this is true... He gave it an enthusiastic drive there, but strange that it was re-starting

I'm talking about the BC Range inaccuracy...

[TheBoy]

To help the OP, although I know its not urgent...

...where does the BC get its tank contents signal from...   ...instrument ECU for those that don't know.

...OP said the gauge didn't read empty, so clearly the BC will have the same view.



So ultimately, its likely to be the float reading isn't accurate when low on the OP's car. Or the Instrument panel has the wrong programming.

It actually uses the same input signal as the instrument ECU, IIRC, not even an output from the instrument ECU, so likely the float has stuck above the bottom of the tank IMHO.

In this scenario (same situation as with LPG) it appears to guesstimate based on tank contents at each start and consumption until it's almost empty, then start counting down the miles. If the float sicks before it starts counting down it will be a tad optimistic.

need to check schems, but if instrument panel missing, I know BC cannot read tank

I'm guessing the instrument panel provides a current source, and reads voltage developed across the resistance of the sensor whereas the MID just samples the voltage on the same line (as does the engine ECU, for some reason - purge control, I guess).

once my obc states there is only 30 miles worth of fuel by flashing the fact i usually fill up pretty soon to be on the safe side!!
