Replacing the Engine Oil

•
Every time the engine oil is replaced, the parameter "Calculated oil dilution" in the PCM
must be reset with the aid of WDS. Therefore, select the option Toolbox
Powertrain Data Reset Engine Oil.

Manual Regeneration

•
If the DPF is blocked due to an excessive soot amount accumulated, it must be
regenerated manually with the aid of WDS. Therefore, select the option Toolbox
Powertrain DPF DPF Regeneration.
•
Depending on the amount of soot accumulated in the DPF the PCM automatically
selects normal regeneration mode (34 min) or long regeneration mode (60 min). Long
regeneration mode is performed when the soot amount in the filter exceeds 125 %. Due
to the longer duration the manual regeneration can be performed at a lower exhaust gas
temperature. As a result, damage of the DPF by a violent regeneration following an over-
accumulation of soot is prevented.
•
In order to cancel the manual regeneration process perform the following procedure:
1. Depress the clutch pedal, shift to 1st gear and verify that the engine speed
decreases to idle speed (manual regeneration is cancelled).
2. Shift to Neutral and increase the engine speed to 3000 min
cooled).
3. If the manual regeneration must be performed again, wait for approx. 5 min before
re-starting the regeneration process.
NOTE: Always perform the manual regeneration in a well-ventilated place and use an
appropriate exhaust-gas extraction system. The vehicle should also not be parked in
front of any flammable or low heat resistant material, since high temperature exhaust
gas is emitted during this process. In addition, the hood should be opened to prevent
the engine from overheating. Do NOT apply electrical load (such as turning on the
headlights or rear window defroster) during manual regeneration, since the post
injection amount is changed and regeneration may not be performed correctly.
