Security Access Error "7F" whilst attempting to calibrate back up camera Audi A3 8V

Hi, my name is Andy and I've been using VCDS on several different cars over the years originally with a HEX-CAN lead and have recently bought a later HEX-V2 lead from Gendan.

Anyway, I've come a bit unstuck with a backup / reversing camera retrofit on a 2017 Audi A3 8V.

The camera install has gone perfect and it's all coded and working perfectly (this is my own personal car) however I'm left with a single fault code for the camera calibration.

I've attempted to follow the calibration guide on the forums here but I can't get past the security access.
When I enter the code "22351" in Module 6C "Back-up cam" and click Do it!, I get the error message "Controller refused to send a seed! Error 7F:Service not supported in active session".

Now, I've tried several times with and without the engine running. Tried MMI resets etc.. Can't seem to get past this.

Does anyone know what exactly that error message is telling me and the normal cause?

I've popped up a few screenshots below and attached a scan. The databus fault message in the scan below is cleared, just the calibration message remains

Any ideas welcome and thanks for the forums.

Just one more point that may be handy for anyone with Virtual Cockpit.

If you do a retrofit that involves removing the MMI unit in the glovebox make sure you don't miss the Optical Databus connector next to the main connector.
I missed this off and you lose all your phone contacts and nav favorites from the Virtual Cockpit screen but not the MMI display. It was a confusing fault until I decided to take out the MMI unit again and check.

Seems the MMI to Virtual Cockpit uses this high speed optical link for only a very few features.

Hi,
Does anyone know what this error "7F" means, I'm still trying to find out. I don't know whether it's and issue with my laptop, VCDS or the retrofit installtion itself.

"7F:Service not supported in active session".

This means that a different (than normal "diagnostic") session is required. I'm not sure this makes a whole lot of sense for a calibration procedure.

Thanks Uwe. It's not a great issue, I'd just like to have a car clear of fault codes if I can. I'm wondering if the camera module I have (although it works fine) isn't quite right for my car.
