I have an 2009 Audi A4 with a door lock issue. The door lock chirp vanished and then I noticed the rear right door wasn't locking. I replaced the lock module and that fixed the door lock. But the car does not chirp when I lock it. Furthermore, I can hear the auto-lock going on every time I slow down to under 10mph or whatever that speed threshold is. I noticed the fuel door is not locked when the car is locked and I replaced that locking mechanism but it did not fix that issue.

It seems the car thinks it's still not locked, perhaps due to the fuel door, and this is why the car does not chirp when the doors are locked and why the auto-locking is always triggered continually at under 10mph?? But I'm not sure where to go from here... Any thoughts?

it looks like it's not very happy with the unlocking mechanism of the fuel tank cap.
and the rear right door is reporting an implausible signal for the locking unit. did you replace it with the correct part number? is the connecter properly seated?

I’ve made sure both the fuel lock and door lock connectors are seated properly and are using the right part #’s. I’m not sure which to look at and for what. It seems like the fuel door is the issue that is keeping the car from fully locking. But i’ve no idea if the rear dock lock has anything to do with the issue at this point.

My experiences from my own car (it's a VW Polo, not sure that counts as a car in the states ;) ) won't lock and arm the alarm unless it's 100% sure all of the doors are properly closed. Your car doesn't receive the correct signal from the RR door:

Check harness at swivel chafe points for damage where mechanical interference is obvious.

No obvious signs of chaffing or harness damage. Can I isolate the issue to the door lock versus the fuel door lock?

You could but is most likely in harness in door which moves being condition sporadic.

Did you verify with test overlay that problem still existed?

All correct part numbers?

Has the locking mechanism been replaced with an OE replacement or is it a Chinese knockoff?
I've had issues in the past where knockoff parts like door latch and lock mechanisms dont play nice with audi.

The correct part number was used for the door lock module, but it was not OEM. Seems the first thing I need to do is replace with OEM and then triage the issue from there. :(

I did not verify with test overlay. I would love to do an additional test, but I'm sorry, I don't know what that means/refers to.
