So.. were you able to get Traffic Jam Assist activated on your Q5?!

Huge thanks to Wolly for cracking the code. I was in at 6am today and very light easter-Monday traffic, but it engaged TJA several times during my drive! The roads still have some snow on the sides, so it wasn't working a lot, but it did engage sub 60kph. You just need cruise control on and ALA to grab 2 lane markers, and then have enough traffic around and then ti goes with the flow sub-60kph.

At first, the stalk button would not turn off ALA. Long story short, I eventually figured out that in the last step (Switch-on condition, lane depart. warn.), the Adaption should be set to "Selection via menu" as opposed to "On" as in the instructions.
After the change, everything works perfectly as far as the ALA is concerned.
I do however have an issue with a warning in the instrument cluster when I turn the vehicle on - it complains about the heated steering wheel not functioning properly. The thing is, I don't have a heated steering wheel. The donor vehicle obviously had a heated steering wheel. I looked around (especially in Module 16), but the Coding button is greyed out, so I can't go in there to see if I can change the settings. A bit of a bummer. Afterwards, I realised that when I did the same mod on my S8, I did not get the error messages about the steering, ACC etc. That's when I remembered that I had not replaced the vehicle's slip ring with the stalk assembly, but used the vehicle's original slip ring. At the time, I had read that if the original slip ring is used, it prevents the steering wheel errors which could require recalibration of the steering angle sensor.
I can't figure out why the "Coding" button of Module 16 is greyed out. I'm going to try to replace the slip ring that came with the "new" steering stalk assembly, with the vehicle's original slip ring - hopefully, that would take care of the heated steering wheel error.

Many/most of us here have been using the OBDeleven device & app to make the necessary coding changes to enable/activate ALA (and now TJA on certain Australian & Canadian 2018 Q5s), so we would probably never see the coding issue you're getting on Control Unit (44) Steering Assistance.
OBDeleven users only need to change the control unit 44 [Heading Control Assistant] parameter value from "not active" to "active". With your VCDS, according to the Mitchfin instruction, you need to "enable" Byte 2 > Bit 7, but instead when you try this you're getting a message saying it's out of range? What does your VCDS user manual say for parameters/locations reporting "out of range" messages?
Wish I could be more help. Hopefully some VCDS users will chime in here to assist. Good luck.

Other people who have the ODBeleven have also posted errors trying to activate 44-Steering Heading Control Assistant which is why I was wondering if anyone who has had those issues could post a fix or if someone who has done it successfully could post the long coding so that I can compare to see if it's something that is different with the 2018 manufactured cars.

Thanks!!
