Hello.

I have problem with my Skoda Octavia 1 2004 1.9tdi ASV 110hp.

On cold start the RPMs are fluctuating from 903rpms to 882rpms. When engine is hot the RPMs droppings are much less frequent.

I am posting video picturing Vcds readings.

Is it normal for RPMs to drop when engine is cold?


The knocking sound is from climatronic flap.

Thank you
