Petrol particle filter

(Applicable to certain variants)

Petrol cars are fitted with particle filters for more efficient emission control.
Particles in the exhaust gases are collected in the petrol particle filter during normal driving. In normal driving conditions, passive regeneration takes place, which leads to the particles being oxidised and burned away. The filter is emptied in this way.
If the car is driven at low speed or with repeated cold starts in a low outside temperature, active regeneration may be necessary. Regeneration of the particulate filter is automatic and normally takes 10-20 minutes.
Fuel consumption may temporarily increase during regeneration.

When driving short distances at low speeds in a petrol car

The capacity of the emissions system is affected by how the car is driven. Driving varying distances and at different speeds is important in order to achieve performance that is as energy-efficient as possible.

Driving short distances at low speeds (or in cold climates) frequently, where the engine does not reach normal operating temperature, can lead to problems that can eventually cause a malfunction and trigger a warning message. If the vehicle is mostly driven in city traffic, it is important to regularly drive at higher speeds to allow the emissions system to regenerate.
