BMW 3 Series Common Problems and Solutions

DPF warning light

Problem:

Has the DPF (Diesel Particulate Filter) warning light appeared on the dashboard? If so, this means the DPF is clogged up. Vehicles fitted with a DPF filter are not suitable for short journeys (using around town etc.).

Models affected:

Solution:

Taking the car out onto an open road and driving at around 2500rpm for about 10-15 minutes in fourth gear will allow the DPF to become hot enough, in order to burn off the unwanted particles. This should remove the warning light from the dashboard.
