Hi if you run out of fuel - is it just a simple case of refilling and off you go ....... or are there set proceedures such as bleeding air out etc..........

I don't think that you will need to bleed the system. The D4 doesn't actually run out of fuel, the engine management tricks you by simulating the effect of running out at a predetermined low fuel level.

If you do run out of fuel there is a precedure to follow once you have put fuel back in. If you do a search you will find out the routine, I seem to remember it involves turning the key to position 2 or the one before the car cranks on a D4 and leave it in that stage for a minute whilst the system primes itself. You may have to repeat this a couple if times but it will save you from flattening your battery turning it over until the fuel gets through.

Yes - so I believe. The manual does also say this:

Note: If the vehicle runs out of fuel it will be necessary to add a minimum of 4 litres (0.8 gallons) of fuel in order to restart the engine. In some circumstances it will be necessary to drive a short distance, typically 1.6 - 5 km (1 - 3 miles) in order for the vehicles monitoring systems to register the additional fuel.

Funnily enough I was playing Fuel Gauge Roulette yesterday




I got 10 miles after that and it was still running fine.
