Read this post, it should answer most of you questions. Post #27 has the install and coding info.

The 95Ah battery is fine. If you purchase the non-dealer battery just change the last digit in the serial number of the currently installed battery by one when using VCDS post coding. Use the BEM code for post coding a dealer battery, or just change the serial number of the old battery. Do not have the Q5 running during the battery install.

I plan to buy the dealer battery tomorrow.
This is the battery difference:
Off Market
VARTA G14 AGM-L5
12V 95Ah 850A 900A 590A
Original
VARTA 4F0 915 105 E
12V 92Ah 520A DIN 850A

That battery is fine.
The only settings you are changing is editing the original BEM code and changing a single character (if you have UDS instead of CAN it's slightly different but almost the same). So there is nothing to backup except the original BEM code if you wanted to for some reason -- just take a screenshot or copy it to notepad.
Don't overthink the battery replacement procedure itself. It's just like your Toyota -- except at the end, you connect VCDS to your car and change the BEM code by a single character to trigger the computer to recognize the new battery. That it is. Not really that much different except you spend 5 extra minutes at the end using VCDS to tell the car that there is a new battery by editing that BEM string.

Thanks for the toyota tip. My wife shows me the blogs of some men who fix cars and tells me I'm good for nothing

Correct! And your 2016 also has CAN like our 2014, so it will be exactly the same procedure as the link provided. Just change that "1" to a "2" at the end and away you go!

Super. I plan to head to the dealer and get the battery from them. Hopefully, they will honor the AED 1200 rate. If not I'll get what they are asking for and do the installation myself.

Another beauty of the simplicity of replacing these batteries is that they are typically pristine and easy to work with, compared to the good old under hood battery we all know and love.

If I put an external battery the third-party warranty and service would be void as well which is expiring in about 15k kms. Didn't want to risk all that so I gave the car to them this morning to get it done themselves.
