VW Polo 9N AWY - Rough idle; Adjust idle speed

Hello everyone!

Is there a way to adjust the idle speed on this Polo, manufactured in 2002, with an AWY 3-cylinder, 55 HP engine, via the engine control unit (ECU)?

Thank you very much in advance, and best regards.

Franz Platzer.

As always, Autoscan helps to determine what's going on.
Please post this (the chassis number can be deleted).

Best regards, Rainer.

Hello!

In the meantime, we have recalibrated the throttle and reset all the learned values!

Thank you for any help!

Best regards,

Hello,

Regarding the idle speed, I couldn't find anything in the documentation.
What you can check:
- Click through adaptation channels.
- Possibly, unlock changes beforehand using login 12233.

I would appreciate your feedback.

Apart from that, there should be a software update available for your control unit.

Best regards, Rainer.

What about deposits in the area of the throttle valve? Perhaps simply cleaning the throttle body and then performing a basic adjustment might help.

"Could you please read the values for the throttle position at idle with the engine at operating temperature (with all electrical consumers turned off). These should be displayed as a percentage." If the value is greater than 5.5%, cleaning is recommended.

Best regards,
