01-Engine - Basic Settings

IDE00457-Test of turbocharger​


HOW-TO run engine's built-in test for turbocharger​

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​
IDE07375 Charge pressure before throttle valve: calculated actual value​
IDE07783 Turbine actuator 1 bank 1: posit.feedback - Uncnd vlt​
IDE07784 Turbine actuator 1 bank 1: posit.feedback - Spec.value​
IDE07785 Turbine actuator 1 bank 1: posit.feedback - Act.value​
IDE07786 Turbine actuator 1 bank 1: posit.feedback - Offset closed​

Select "Log" (if so desired or just monitor the values) > Start (logging)​

Select "Go!" (to start the test)​

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
Output Tests
  • IDE00234-Exhaust turbocharger 1
  • IDE00237-Turbocharger recirculation valve


Comments, ideas, proposals, data log contributions etc. more than welcome :thumbsup:

IDE00897-Adaptation of the turbocharger​

Nothing seems happen at the turbo while adapting it - as in the graphs below.

However, the ECU reports the procedure has finished correctly - which is not always the case, as e.g. in thread Wastegate actuator adaption CXEB
