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)​

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.

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

IDE07136-Test of wastegate actuator​

Presumably the test is valid only on Bi-Turbo engines.

Love it ..

I'll run the test on mine when I get it back .. (new engine with new turbo)
