I have recently bought a used 2022 Tiguan, SE. the check engine light was on (p0491 - insufficient air flow bank 1) so when trying to check the air pump I found this socket dangling alone near the air pump, so where does it go? Is it related somehow to the air pump?
It's also worth mentioning that I found the fuse related to the air pump broken, and when short circuitting it I didn't hear any noise coming from the air pump.
