It’s freezing cold in Canada, like -30•c. Maybe pull to hard on the handle🙄

As you mentioned, there are two cables inside the rear door. One is connected to the inside handle, and is part number 8K0 839 085 A. The ECS website carries this one (ECS part number ES#451466 for $32.22). The description is Rear Door Latch Release Cable - Bowden cable from inside door handle to latch - Fits left or right side ... Inside door release not working? A common problem is the Bowden cable stretching or breaking. It looks like this:



However, you said that you cannot open the door from the outside, only the inside. Therefore the other cable, part number 4H0 837 099 B is the one you'd need. The ECS website shows this one (ECS part number ES#2595542 for $38.33). The description is Door Bowden Cable - Fits the left and right side. Fits the front and rear doors from the 2013 model year (but the chart shows it fits the B8 S4 -- you didn't mention your car's year so check to verify the part number). ... The bowden cable attaches the exterior door release to the door latch assembly, allowing you to release the latch from the outside of the vehicle cabin. If this cable fails, the outer door handle will no longer open the door. It looks like this:



I assume you need to remove the inner door card to have access to replace this bowden cable. Might be a DIY video to illustrate the process you'll need to follow for this repair. Alternatively, someone here on AZ can offer advice as to what needs to be done to replace the cable. Also, the part may be available for less at other on-line parts websites. ECS is a reputable vendor though that I've used in the past, and trust.

Just noticed that if that picture of the cables you included is from your car, than apparently you got the door card off. The cable with the yellow plastic piece at one end has a white plastic piece at the other end. In your pic it looks like the white plastic piece could be broken, so that could be your problem. Here's what a new one looks like:



It would be part number 10 in this diagram:

Yes, door Bowden Cable Part #4H0837099B, that's exactly what I need. The interior panel is already removed, the edge of the Bowden cable link to exterior handle is removed. However, I don't know how the remove the link of the other end (the yellow side). I can't access the other end, do I have remove the lock actuator? Not to sure how to proceed.

Yeah here's a picture of my old lock actuator. I replaced it with a used one that came with a new cable. The cable is easy to remove once the actuator is out of the door.20190131_061421.jpeg20190131_061424(1).jpeg

Yeah, undo those bolts

This is the DIY video that I used when I replaced my accuator. I was thinking of keeping it for parts, but I do that too often and tossed it. There's someone parting out a car in the classifieds.

Dude, that's awesome! I'm glad the overall repair was painless, and am happy you're approaching the finish line soon.

Rest assured, man. I live in the same country. Sometimes, you can't use brute strength to solve your problems if things aren't going your way.

These German cars are like delicate flowers, so be sure to take heed next time!

In all seriousness, I wish you luck with this - from a fellow Canuck to another.
