Conditions:
- ignition ON
- engine speed = idling
- engine temperature > XX °C (XX - Measured values group XXX, field X)
- clogging of Diesel particulate filter < MAX (XX - Measured values group XXX, field X)
- appliances ON (Headlights, air-conditioning, Seat heating)
Note:
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!
Conditions - test drive
- speed XX-XX km/h
- engine speed XXXX-XXXX rpm
- engaged gear (X) or (X) or (Tiptronic)
- duration XX-XX minutes
- temperature upstream of component: turbo blower > XXX °C
- second mechanic necessary!
Check of clogging level of Diesel particulate filter
connect with the control unit XX - engine
XX - Measured values group XXX, XXX
observe values: group XXX
field X = xxxxxxX = regeneration
field X = xxxxxXx = rapid regeneration
field X = regeneration counter
observe values: group XXX
field X = temperature upstream of component: catalyst
field X = temperature upstream of component: Diesel Particulate Filter
field X = clogging of Diesel particulate filter
field X = temperature downstream of component: Diesel Particulate Filter
ascertaining the km and time since last regeneration
connect with the control unit XX - engine
XX - Measured values group XXX, XXX
observe values: group XXX
field X = previous regeneration - distance
observe values: group XXX
field X = previous regeneration - time
DPF regeneration
connect with the control unit XX - engine
XX - Login / XX - Coding II / XX - Security access
enter value: XXXXX
Start
do a test drive if filter clogging is not close to X
XX - Measured values group XXX, XXX
observe values: group XXX
field X = xxxxxxX = regeneration
field X = xxxxxXx = rapid regeneration
field X = regeneration counter
observe values: group XXX
field X = temperature upstream of component: catalyst
field X = temperature upstream of component: Diesel Particulate Filter
field X = clogging of Diesel particulate filter
field X = temperature downstream of component: Diesel Particulate Filter
Note:
If regeneration fails or it is incomplete, probable error in procedure or engine.
