IFPS from BMW to prevent misfuelling

Incorrect Fuelling Protection System (IFPS) will now be fitted as standard to all diesel-powered BMW cars. IFPS prevents the fuel filler nozzle of a petrol pump from entering the fuel tank neck of a diesel-powered car.

BMW has introduced the system to prevent some of the 150,000 cases of misfuelling that occur in the UK every year. 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.

In the new IFPS system, larger diameter diesel nozzle is able to touch two opposing contact patches that then releases the locking system, allowing the nozzle to engage.
