Conditions:
- clutch pedal - pedal switch - faultless

- second mechanic necessary!

- observe the occupation safety rules when taking a test drive with connected diagnostics tester

- 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 = XX%

do a test drive approx X minutes
- engaged gear (X) or (X)
- engine speed = XXXX rpm - XXXX rpm

do not interrupt driving

connect with the control unit XX - engine

XX - Measured values group XXX
required values:
field X = X% - XX%

if values are not achieved - execute function: DPF regeneration

observe values: group XXX
field X = XXXXXXXX or XXXXXXXX (DPF regeneration - status)

observe values: group XXX
field X = temperature upstream of component: turbo blower - actual value
field X = temperature upstream of component: Diesel Particulate Filter - actual value
field X = temperature downstream of component: Diesel Particulate Filter - actual value
field X = clogging of Diesel particulate filter - actual value

do not interrupt driving - if filter clogging is close to X%

required values:
field X < XX%

upon achievement of values - end the test drive
