Where is the vanos? And what is it... sorry

Sorry, I do not understand 'VANOS'

I believe the item indicated in your image is the timing chain cover. It encloses the chain that drives the cams operating the exhaust and inlet valves.

As per @Warrior193 it is the upper timing chain cover. For the part number and new genuine part price you an use LLLP parts per @Breezy_Pete

I'm assuming that the OP has suffered terminal issues with their EA888 engine - hence the replacement in image?

Quite possibly, It is the 1.8tsi EA888 gen 2! 🙄 Or they have just found the replacement engine image and used it to ask the question.  The upper timing cover is plastic and has a replaceable seal from memory. The lower cover bends on removal and is best replaced with new after removing and requires sealant applied.
