STATUS
DEFINITION
Statuses ET742 to ET751 correspond to the causes for the regeneration request. They
are associated with the parameters PR816 Stored regeneration start No. 1 to PR825
Stored regeneration start No. 10 which contain the record of the vehicle mileage at
the start of regeneration (e.g. PR745 Stored regeneration start No. 4 is associated
with ET745).
NOTESSpecial notes:
These statuses should only be interpreted for ALP 9 Particle filter warning light
comes on too frequently.

the particle filter, without the particle filter warning light coming on.
STATUS2Request by estimated weight of soot
Regeneration was requested based on an estimation of maximum soot weight in the
particle filter, without the particle filter warning light coming on.
STATUS3Request by distance travelled
Regeneration has been requested after a maximum distance has been travelled
since the last successful regeneration without the particle filter warning light
coming on.
STATUS4Request by number of regeneration failures or weight of soot
