The air filter is in a rectangular black box under the bonnet (left wing of the car). You'll need a screwdriver with Torx 20. Eight self-regulation covers are being crushed.

It is recommended that the replacement of an air filter be performed through one TVE. But many owners of Tiguans change it every time the oil is changed.
