Before we start, I want you to know this. All risk is yours. It's not easy to break the car with coding, but that doesn't mean you won't. While coding, do exactly the same steps as below.
NOTE: Sometimes VCDS cannot see the 5F module. I don't have a solution for this unfortunately.
One More Note: Don't forget to open the hood of the car. Otherwise, you cannot make changes. The hood is the firewall of the car
VCDS or OBDEleven is required to unlock Audi A4 B9, Audi A5 B9 hidden features. I recommend using OBDEleven. Simple to use. It's simpler to revert when a problem occurs. The risk is reduced if you back up all control modules without making any changes.
Addition: You can also do this using Odis engineering or VagCanPro. But the codes may not be exactly the same.

Note: Increasing the time will also enforce a higher threshold of confidence level for a road to be qualified for lane keep (green lane marks on indicator). Meaning that the car might need clearer lane markings and overall better vision for lane assist to engage.<-Personal experience, not tested systematically and no confirmation from Audi.

Enable use of external SIM
Description: Enables detection of the external sim card slot in the glove box and the supporting Data Connection menu to input the carrier APN. Note that this is mainly for using an external SIM for the WIFI hotspot functionality. This will not give you the Audi Connect services (Google Maps, etc..) for free though if you have an active Audi Connect subscription then its data will in theory also go over the external SIM.
- 5F - Information Control Unit
- Adaptation (10)
- Search for the adaptation: “Internal SIM card, use”
- Change value to: “Automatic” (default is: “Always”)
- Reboot MMI
- While in the MMI: Settings -> Connection Manager -> Data Connection -> Online Settings -> Data Connection Settings-> Connection Settings -> Enter your carrier’s APN and Username / Password (if necessary)
- This step applies only if you’ve inserted your own data SIM into the glove box slot, otherwise it will still use the internal eSIM.
- APN for Google Fi data SIM: h2g2 (Leave username & password blank)
- APN for AT&T data SIM: phone (Leave username & password blank) <- untested
Automatic Opening of the Car When Approaching
Description: The car will automatically open when you are about 1-2m away.
Note: Tested on 2018 S5. Since the car is missing some key detection sensors(my guess), If your key is low on battery or you stayed at some distance away when the key’s signal is faint, it will actually trigger the alarm system (presumed Relay attack) and throw an error code B131D29 in Comfort System Module stating: Implausible signal. (I understand that what we are trying to do should not have caused this error to be thrown, but this only happened after I had adopted this tweak. Take it for what it’s worth.)
2nd Note: Enabled on a ‘19 RS5 - works 95% of time. Must approach the car from front or side. Approaching the car from the back rarely results in the unlocking of the car.
