Conditions:
- engine temperature = XX°C +
connect with the control unit XX - engine
Start the engine
engine speed = idling
wait XXs
Advanced Measured Values
select item in menu:
IDEXXXXX-ENGXXXXXX - temperature of exhaust gases X-TEG_MES[X] (temperature upstream of component: turbo blower)
IDEXXXXX-ENGXXXXXX - temperature of exhaust gases X-TEG_MES[X] (temperature upstream of component: Diesel Particulate Filter)
IDEXXXXX-ENGXXXXXX - temperature of exhaust gases X-TEG_MES[X] (temperature downstream of component: Diesel Particulate Filter)
TIP! For easier search in the menu, enter the code IDE, ENG or MAS into the "Filter" window
increase rpm to XXXX rpm
desired condition:
X-TEG = increasing - strongly
X-TEG, X-TEG = increasing - moderately
X-TEG > X-TEG > X-TEG
for this test, it is suitable to use graphical representation VagScope
example:
if values are not achieved - check component:
- temperature sensor
- wiring
- connector connections
- engine temperature = XX°C +
connect with the control unit XX - engine
Start the engine
engine speed = idling
wait XXs
