Default Front & Rear Fog Lights Do Not Turn On; Replaced Headlight Switch; Same Result

I've had the ongoing electrical problem where both the front and rear fog lights Do Not Turn On. I figured, the original Headlight Switch by Audi went bad. I received the replacement part today (Made in China; eBay) to see if that would resolve the issue, but it was no success. The eBay Headlight Switches are positively discussed across the Audi Forums; seems like the problem may not be residing in the switch at all. Both Driver and Passenger Side Fog Lights (Front and Rear) do not turn on. Would greatly appreciate feedback on this. Thank you.

Also, High Beam Does Not Work in Fixed Position; I always need to push the lever towards me to engage the high beam.

Are these issues isolated, or do they follow to a common Audi Problem?

I assume you checked ALL fuses?

Ah, I remember messing with the fuses a few months back. I'll check the fuse box and post an update. Thanks

Good thing, fuses are cheap.

I checked the Fog Light fuses by swapping out the Cigarette Lighter Fuse with the Fog Light Fuse vice versa, and vice versa. The Fog Light Fuse works in the Cigarette Lighter Fuse. Where should I look into next? Thanks

Default Wasn't there a recall on the headlight switch wiring?

I've asked Audi on several occasions if all the recalls on this vehicle were addressed, the headlight switch wiring was never one of them,

This car is just plagued with electrical problems, ironically, they seem to all be focused on just the front driver side.

Other electrical problems pertain to the Car's Door Lock Switch / Alarm System,

10 Faults Found:
01371 - Alarm triggered by Door Contact Switch; Driver's Side
35-00 - -
01572 - Alarm triggered by Door Contact Switch; Passenger Side
35-00 - -
01374 - Alarm triggered by Terminal 15
35-00 - -
01369 - Alarm triggered by Hood Switch
35-00 - -
01368 - Alarm triggered by Luggage Compartment Switch
35-00 - -
01373 - Alarm triggered by Radio Ground Contact
35-00 - -
01559 - Drivers Door
58-00 - Can't Lock
01561 - Left Rear Door
59-10 - Can't Unlock - Intermittent
01574 - Alarm triggered by Door Contact Switch; Right Rear

Checked relay operation?

Suggest you do a full scan, save or print the output of errors on all modules - and clear all codes. This way you'll know what are current issues (codes will return) and what is remnants of something that isn't relevant anymore.

Some workshops use different software and DB; They'll tag the code as the issue is fixed, but not clear the code(s) (for future referance - in case an issue returns, they can see related history and previous issues). But not all software or teminals can read/access these tags.

I'm suspecting the relay for the Fog Relays; High Beam as well;
Signal Stalk is only a problem when moving the lever forward for keeping High Beam On. High Beam doesn't to appear on the Dashboard and High Beam only work when pulling the signal stalk toward me.
