DPF Manual Regeneration

• If the DPF indicator light is illuminated and the DPF is blocked due to an excessive soot

amount accumulated, it must be manually regenerated with the aid of M-MDS. To

perform the procedure select the option ToolboxÆPowertrainÆDPFÆDPF

Regeneration and follow the instructions of M-MDS.

• 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).

• 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

-1

for 1 min (DPF is

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 stationed

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.

NOTE: If the exhaust gas temperature during manual regeneration exceeds a certain limit,

the PCM stops the regeneration process and increases the engine speed to

2500 min

-1

to cool the DPF.

NOTE: Depending on the amount of soot accumulated the PCM performs normal and long

regeneration mode one after another, i.e. the regeneration process may take up to

94 min. If the DPF indicator light does not extinguish after the manual regeneration is

finished, perform the regeneration process again.
