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
- Do in the open air - Risk of fire
- Regeneration dopes not make sense when clogging is below: XXg (Advanced Measured Values -> IDEXXXXX-ENGXXXXXX a IDEXXXXX-ENGXXXXXX)
- During the process, do not manipulate the pedals, appliances, brakes, bonnet and the vehicle.
!!! 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! Maximum value = XXg !!!
Check of clogging level of Diesel particulate filter
connect with the control unit XX - engine
Advanced Measured Values
select item in menu:
IDEXXXXX-ENGXXXXXX - clogging of Diesel particulate filter - calculated value
required value < XXg
IDEXXXXX-ENGXXXXXX - clogging of Diesel particulate filter - measured value
required value < XXg
TIP! For easier search in the menu, enter the code IDE, ENG or MAS into the "Filter" window
!!! 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! Maximum value = XXg !!!
upon achievement of values - continue
do a test drive approx X minutes
- engaged gear (X) or (X)
- engine speed = XXXX rpm - XXXX rpm
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-ENGXXXXXX - temperature of exhaust gases - temperature upstream of component: turbo blower required value: >XXX°C
IDEXXXXX-ENGXXXXXX - temperature of exhaust gases - temperature upstream of component: Diesel Particulate Filter
required value: >XXX°C
IDEXXXXX-ENGXXXXXX - temperature of exhaust gases - temperature downstream of component: Diesel Particulate Filter
required value: >XX°C
upon achievement of values - continue
XX - Security access

XX - Basic settings
X) select item in menu: IDEXXXXX - DPF regeneration
X) In the Basic Settings window, click Measured values and select the items you want to visualize.
IDEXXXXX-ENGXXXXXX - Exhaust gas temperature sensor X-TEG_MES[X]
IDEXXXXX-ENGXXXXXX - Exhaust gas temperature sensor X-TEG_MES[X]
IDEXXXXX-ENGXXXXXX - Exhaust gas temperature sensor X-TEG_MES[X]
IDEXXXXX-ENGXXXXXX - Diesel Particulate Filter: soot clogging: calculated value
IDEXXXXX-ENGXXXXXX - Diesel Particulate Filter: soot clogging: measured value
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-ENGXXXXXX - Diesel Particulate Filter: soot clogging: calculated value < Xg
- IDEXXXXX-ENGXXXXXX - Diesel Particulate Filter: soot clogging: measured value < Xg
- basic settings - Successfully completed
