BMW´s misfuelling system now on diesel-engined 7-series
Published: 13 December 2007
BMW has introduced a system to prevent some of the 150,000 cases of misfuelling that occur in the UK every year.
The Incorrect Fuelling Protection System (IFPS) will now be fitted as standard to all diesel-powered BMW cars, reflecting moves by Ford to prevent drivers accidentally filling diesel engines with unleaded petrol with its EasyFuel system introduced on new Mondeo and Focus models.
MotorTorque recently published an FAQ on misfuelling aimed at providing information and guidance for motorists worried about misfuelling.
IFPS prevents the fuel filler nozzle of a petrol pump from entering the fuel tank neck of a diesel-powered car. The larger diameter diesel nozzle is able to touch two opposing contact patches that then releases the locking system, allowing the nozzle to engage. A petrol pump nozzle can not make the same connection and this access is blocked.
The system was initially introduced on 1, 3 and 5 Series, and X3 cars in March, but is now also fitted to 6 and 7 Series and X5 models.
BMW reckons its introduction will prevent most of the 1,000 cases a year of misfuelling that occur on BMW cars, which can cost owners thousands of pounds to rectify.
Good news for BMW-owning fuel fools.
