Conditions:
- clutch pedal - pedal switch - faultless
- Error memory empty
- fuel tank contents > XXl
- engine temperature > XX°C
- temperature of exhaust gases > XXX°C
- appliances ON
- engaged gear P/N
- parking brake ON
- bonnet closed
- engine speed idling
- During the process, do not manipulate the pedals, appliances, brakes, bonnet and the vehicle.
- Do in the open air - Risk of fire

!!! If the filter is clogged above the maximum value, it is necessary to replace it with a new filter otherwise there is a risk of fire during regeneration!!!
(Advanced Measured Values -> IDEXXXXX - clogging of Diesel particulate filter - Maximum value)

Check of clogging level of Diesel particulate filter

connect with the control unit XX - engine

Advanced Measured Values

select item in menu:

IDEXXXXX - clogging of Diesel particulate filter - Maximum value
IDEXXXXX - clogging of Diesel particulate filter - calculated value
IDEXXXXX - clogging of Diesel particulate filter - measured value

TIP! For easier search in the menu, enter the code IDE, ENG or MAS into the "Filter" window

desired condition:

IDEXXXXX - clogging of Diesel particulate filter - calculated value < IDEXXXXX - clogging of Diesel particulate filter - Maximum value

IDEXXXXX - clogging of Diesel particulate filter - measured value < IDEXXXXX - clogging of Diesel particulate filter - Maximum value

!!! If the filter is clogged above the maximum value, it is necessary to replace it with a new filter otherwise there is a risk of fire during regeneration!

upon achievement of values - continue

engine speed: idling

Advanced Measured Values

select item in menu:

TIP! For easier search in the menu, enter the code IDE, ENG or MAS into the "Filter" window

IDEXXXXX - temperature of exhaust gases - temperature upstream of component: turbo blower required value: >XXX°C

IDEXXXXX - temperature of exhaust gases - temperature upstream of component: Diesel Particulate Filter
required value: >XXX°C

IDEXXXXX - temperature of exhaust gases - temperature downstream of component: Diesel Particulate Filter
required value: >XXX°C

upon achievement of values - continue

IDEXXXXX - Exhaust gas temperature sensor X
IDEXXXXX - Exhaust gas temperature sensor X
IDEXXXXX - Diesel Particulate Filter: soot clogging: calculated value
IDEXXXXX - Diesel Particulate Filter: soot clogging: measured value
IDEXXXXX-ENGXXXXXX - Phase - regeneration

TIP! For easier search in the menu, enter the code IDE, ENG or MAS into the "Filter" window

X) basic settings - Start

X) follow the diagnostics instructions

X) During regeneration, monitor the exhaust gas temperature sensor. A sudden change of more than XX°C indicates a defective sensor

desired condition:
- IDEXXXXX - Diesel Particulate Filter: soot clogging: calculated value < XXg
- IDEXXXXX - Diesel Particulate Filter: soot clogging: measured value < XXg

X) basic settings - end

XX - end of communication
