IDE00457-Test of turbocharger
HOW-TO
Engine running
VCDS > Select > Engine > Basic Settings > IDE00457-Test of turbocharger
Select "Measuring Values"
Pick up e.g. the following data items for monitoring:IDE00021 Engine RPM
IDE07736 Turbocharg.2 compress.outlet: press.sensor 1 bank 1: raw value (bi-turbo only)
IDE07738 Charge air cooler inlet: pressure sensor 1 bank 1: raw value
IDE07783 Turbine actuator 1 bank 1: posit.feedback - Raw voltage
IDE07784 Turbine actuator 1 bank 1: posit.feedback - Spec.value
IDE07785 Turbine actuator 1 bank 1: posit.feedback - Act.value
IDE07790 Bypass valve for turboch 1 turbine inlet: activation (bi-turbo only)
IDE07791-ENG180364 Turboc.1 turbin.bypass valve 1 B. 1: pos.feedback - Raw voltage-Voltage_16_usigned_1000 (bi-turbo only)
Select "Log" (if so desired or just monitor the values) > Start (logging)
Select "Go!" (to start the test)




EDIT: Graphs replaced with better ones - to show engine RPM to allow align events.
At the time of testing the engine in question has done 100.000 km (60.000 miles).
The test runs actuator/sensor G581 into two different positions. Test takes 60 seconds to complete.
In the initial setup only the two data items were active - obviously need to investigate a bit more to make the recording more useful.
In the next episodes:
Basic Settings
- IDE00891-Test of charge air pressure control
- IDE00897-Adaptation of the turbocharger
- IDE07136-Test of wastegate actuator
- IDE07464-Turbocharger recirculating valve test
- IDE11075-Adaptation of turbocharger recirc. valve
- IDE00234-Exhaust turbocharger 1
- IDE00237-Turbocharger recirculation valve
- IDE02594-Exhaust bypass valve
Comments, ideas, proposals, data log contributions etc. more than welcome
