NOTE
In the case of a particle filter heavily loaded with soot, it can occur that the regeneration
request is blocked again after a short time or is not released. Drive the vehicle for
approximately 30 minutes at a constant speed. Then perform the Particle filter
regeneration service again.
During the regeneration phase and with the engine running, it can also occur that the
display for “Regeneration active” jumps to “Regeneration not active”. This behavior can
be seen exclusively with the vehicle stationary with the engine.
Particle Filter Test
It is advisable to carry out a series of particle filter tests as a result of constant DPF
regeneration, such as checking oil level, oil change interval for diesel contamination, swirl
flaps, backpressure sensors and particle filter soot remains.
