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 in a motorway or cross-country
trip taking approx. 30 minutes at a speed that is as constant as
possible. Subsequently, the service function “Particle filter
regeneration” must be run again.
NOTE: 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
running. This behavior does not impair the scheduled course
of the regeneration in general.
11.3.5 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) From the service functions menu (Figure 11.11) use the
UP/DOWN scroll button to select Particle filter test and press
the OK button.
