Idle speed adjustment

[robert_ford]

Hello,

I have a little question. In PCM module I have an option: "IDLE SPEED ADJUSTMENT". When I "read from module" I get there "0000".
Mondeo MK5 2.0 diesel has normal 800 RPM on idle. Is it possible to increase RPM on idle, for example to 850-900RPM?

I'm new with UCDS, so I don't want to brick my PCM. Can I directly enter there value for example: 900 ?

I have vibration at idle and I want to test. When I manually increase RPM by gas pedal, vibrations are gone.

I will be very grateful for any suggestions.

Thanks
