running out of fuel

[maelgwn]

That's really interesting that you don't trust the MFD. Mine is within 0.1L/100km of the calculated figure.

You realise that you can tweak the L/100 average with VCDS?

Yeah I know, I just don't have VCDS.

Mine is about 10% optimistic vs fill calculations in stock tune and about 5% with the remap. I'd say your accuracy is exceptional as our Golf is similarly optimistic.

Why would the accuracy change with a remap? Isn't the calculation basically a combination of the amount of fuel going through to the injectors & the distance travelled?

Yes and No, it's the amount calculated from the injectors ON time.

Has anybody any experience in running out of fuel in a diesel?

I've never run out of diesel, but as gldgti says, the fuel system in Golf and other 4cyl. TDI should self bleed. Just turn the ignition ON/OFF several times and crank the engine, it will eventually start, just make sure your battery is healthy and in a good state of charge. Otherwise you get stranded even if you carry the 20L jerry can to fill up, once you runout of fuel.

The V6 TDI could be a different story when you run your tank dry, and some other Euro diesels like MB may need a lot of cranking before they start and in the process you could flatten even a fully charge battery.

As they say "top tip"!
