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.
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.
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, the screen
displays as below. Select Cancel to exit this function.
