In Vdiag 18, 1C, 54:
Each parameter between PR816 and PR825 contains the vehicle distance stored when particle filter regeneration
starts when driving. Each parameter is connected with a status "Regeneration request status record". They are
recorded simultaneously (for example PR819 is associated with ET745 Stored regeneration request status
No. 4).
Each new recorded value is saved under the next PR (PR+1).
When all ten parameters have a value other than zero, and a new regeneration starts when driving, the distance
information for PR816 is cleared and replaced by the new value.
For other Vdiags:
Each parameter from PR816 Stored regeneration start No. 1 to PR825 Stored regeneration start No. 10
records the mileage when particle filter regeneration starts for which the status request is recorded in ET742
Stored rege*. request status No.1 to ET751 Stored rege*. request status No.10. (for example PR819 Stored
regeneration start No. 4 is associated with ET745 Stored rege*. request status No.4).
Each time a new regeneration when driving is started, the vehicle mileage is recorded in PR816, as well as its
status in ET742.
PR816 to PR825 operate through successive copying (when regeneration starts, the value of PR816 is copied to
PR817 Stored regeneration start no. 2, the value of PR817 is copied to PR818 Stored regeneration start no. 3
and so on).
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
