I got called out to a job last night in South London for a nice young couple with a Range Rover Sport Diesel, that had been filled with 40 quid of Petrol. What was interesting is that these cars are fitted with an in-built misfueling prevention system!
What happens, or is supposed to happen is that when you put in the wrong fuel, the car detects it and closes the filler neck and stops you filling up, which in this case it didnt work until 40 quids worth had gone through.
The car was new and the client had been told by the dealer that “its impossible to missfuel the car” – I think it gives a false sense of security, and put her off guard.
The long and the short is that factory fitted misfuelling devices are an infant technology and I dont think they quite there yet, also they are flimsy plasticy things and I would be interested to see how they stand up over the test of time – I have already come across a few that are constantly kicking in when the car is filld with the right fuel, and being part of the filler neck it’s main dealer territory.
Anyway, the car was drained and filled up with the right stuff and on her way in 30 minutes.
The manual for the car does have a little piece about “it is your responsibility to put the right fuel in your car and any damage that results….” – which gets them off the hook if the device plays up. The book also has instructions for the reset and provides a yellow “reset tool” – which is a bit of plastic that you push down the filler neck to reset – very simple
The tool is in the boot, next to the spare tyre, it is yellow and is about 9 inches long, the instructions for using it are in the manual – which should be in the glove box, but in short, this is what you do
1) get the tool, it has 2 prongs on the end, if you look into the filler neck you will see where these prongs fit in
2) put the two prongs in the neck and pull it gently, this resets the misfuel fuel filler flap door
3) your car can now be refueled, do not refuel your car if you have misfueld – check the FAQ’s section for further details
