frequencyWhat to tell the
customer?
Output 1The last 10 regeneration
attempts have failed due to
the engine cutting out.Regeneration failures

the need to wait until the
end of regeneration
(warning light goes out)
before switching off the
engine.

not because of the engine
cutting out.Unsuitable driving
conditions.No regeneration
frequency analysis.Explain again to the
customer the driving
criteria for when the
warning light comes on.
Output 3After successful
regenerations stored in the
memory, the warning light
did not come on. No
interval can be calculated.Since the last successful
stored regenerations, the
driving conditions have not
allowed the warning light to
come on.Should be normal Vehicle correct
Output 4The interval between a
successful regeneration
and the particle filter
warning light coming on is
correct (above the lowest
possible values). The
system does not have any
irregular components.Unfavourable driving
(urban zone, underspeed,
