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. In this case, it is required to regenerate the particle
filter by driving the vehicle for approximately 30 minutes at a constant
speed. Subsequently, the service function “Particle filter regeneration”
During the regeneration phase and with the engine running, it can
also occur that the display message changes from “Regeneration
active” to “Regeneration not active”. This behavior can be seen
exclusively with the vehicle stationary.
5.8.5 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.
1. Tap Particle filter test from the service functions menu.
2. The tool communicates with the vehicle and reads the fault
codes memory. If there is no relevant fault code stored in DDE,
