An innovative fuel system has been introduced to stop some of the 150,000 cases of mis-fuelling in the UK that occur every year*. The device, called Incorrect Fuelling Protection System (IFPS), is now fitted as standard to all diesel-powered BMW cars.
IFPS works by preventing 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. This allows 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. Its introduction is expected to prevent most of the 1,000 cases a year of mis-fuelling that occur on BMW cars which can each cost owners thousands of pounds to rectify.
