D4 miss-fuel flap reset tip
hi.. no I have not miss-fuelled my car but over here sometimes the diesel pumps are just petrol ones with the fuel changed, so the nozzle is a petrol one (smaller dia.) so I have come accustomed to resetting the little yellow flap that should prevent miss-filling. here are my observations
1) the flap does not prevent you from filling, it only slows the flow so the auto lock fill (don't know it's correct name) will not lock and you have to manually squeeze the trigger. so not so fool proof.
2) one sign is fuel will spit back out from the filler if you try to fill on full flow.
3) the important bit...the flap will not reset if it has not fully deployed. you will need to poke the black bits of plastic inside the filler tube with a pokey thing (these actuate the flap if a smaller than diesel filler tube is inserted)
4) using the yellow reset tool it must be inserted at the deepest point first then draw it out. no great force is required the flap will reset with a click out of sight. if you dont't insert at the deepest part of the two slots the flap will need poking a bit.
5) use the handfull of babywipes you keep wrapped in cling film next to the reset tool to clean your smelly diesel hands.
6)curse and promise not to use that station again...unless its needed

When I had originally picked my D4 up from the dealer this 'flap' had been triggered and it took ages to fill a tank of fuel. I searched but couldn't find the 'reset tool' anywhere on-board so it was back to the dealers where one was 'liberated' from a showroom model. Now it will probably never be needed again!!!

Where would I locate the tool?
As I am sure this has happened to mine as it takes 10 mins to fill up.
Thanks in advance

Re: D4 miss-fuel flap reset tip
Not quite sure why they describe it as Fuel guard if it doesn't do just that
This is the formal operation description from LR
Quote:
The fuel guard system comprises a mechanically operated flap which is triggered when the smaller diameter filler nozzle tube, used on petrol (gasoline) pumps, is inserted in the filler neck. The flap is actuated and blocks the sensor port on the fuel pump nozzle, causing it to automatically switch off. The flap is locked in this position by a latch mechanism.
A reset tool is provided and stored in the luggage compartment. The tool is used to reset the fuel guard device if triggered and release the latch. Two spigots on the tool locate in slots in the filler neck which release a latch and the flap is opened by its own spring. The tool is located in the filler neck and once the two spigots on the tool are located in the slots it can be pulled outwards, releasing a latch and allowing the flap to be opened by its own spring pressure. The tool is stored on the battery mounting clamp.
The flap is colored yellow so that it is clearly visible when activated and has a 'Handbook' symbol on it.
A diesel fuel pump nozzle will not activate the fuel guard because the nozzle stops against two molded lugs. However, if an unleaded gasoline pump nozzle is inserted into the housing, its smaller diameter allows it to pass the two molded lugs. The nozzle strikes two pins on the inside of the filler housing which move forward. This movement rotates the shut-off flap which is then held in place when the nozzle is removed by the latch mechanism.
NOTE: Russian markets do not use the fuel guard system and are fitted with a conventional filler neck.
As I am sure this has happened to mine as it takes 10 mins to fill up.
