Both parking lights at the front suddenly do not light up (self.mechanicadvice)

The two parking lights in the front of my car suddenly do not light up anymore. It's a 2008 VW Passat B6 Variant.

Possible leads:

Fault code: Electrical fault in circuit
A multimeter shows that the sockets which fit the parking light do not receive any power - on both sides.

Already checked:

The bulbs are okay
The fuses are okay
The parking lights in the back are okay
All other lights are okay

Any advice? Is there anything else a layman could check before sending it to the garage?

Multimeter - check for voltages at the fuse points, and very carefully (car is fully off) check the electric resistance across the circuit at the fuse points to check for open circuit or shorts.

If you have an open circuit, you can use a toner to try to find where it actually ends in your car, and then fix the cable

My guess is some corrosion at a connector, probably near where water would go. Near the headlight

Thank you so much for the advice!! This is outside my comfort zone but I've been looking up videos on YouTube, it seems doable!
