What to do if the FAP indicator on your Smart Forvision lights up?

Do not accelerate too much either, it may damage the vehicle. It is advisable to climb to 3000 rpm. The temperature of the vehicle will thus burn these stored dirt, and thus release this FAP. If this procedure really does not work, you will have to replace it with a new one.
