Hi.

In the actuator diagnosis process, the N75 valve appears after the N109 valve.

How can I then test the N75 with the engine running, if previously each time the vehicle is shut down via the N109 icon_evil.gif?

I'm sorry, I don't understand the question. Could you please rephrase it?

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

hello,
press faster icon_wink.gif.
Then my engine makes a brief sputtering sound, but then it continues to run.
greetings

[Translating...]no way...

mein ALH geht aus und bleibt aus. man kann ich nicht wiederstarten. erst muss der stellgliedtest beendet werden..

aber man kann was anderes machen:

jeder kennt die basic-settings auf kanal 000 zum prüfen des einspritzbeginns...

Yes, I was just browsing some EDC websites a little while ago.

I also found the basic settings in the other channels, but nothing has changed cyclically (like with the actuator diagnosis).

Or maybe I was just too impatient.

On the other hand, I realized that with the wastegate N75 valve, not much will happen at idle anyway – except perhaps that the rattling of the valve might stop.

But thank you for the link.

The selected topic or contribution does not exist.

Can anyone explain this again? After the actuator diagnosis for N109, my 1Z (with wastegate) is also out - I can click as much as I want, but I can't get it to "flutter" like the N75 icon_confused.gif.

Does it accept throttle input during the actuator diagnosis?
If applicable, try this: Bring the engine up to approximately 3000 rpm, then double-click the buttons for N109 and N75 while the RPM drops towards idle.
However, I am skeptical about whether N109 will receive power again during the following actuator test (N75).

Why not try using MWB11 and the basic settings, which switch approximately every 10 seconds?
