Enable Park Assist

This is a major PITA job.
I had the zFAS unit updated to the 295 SW
Installed the P button to the console
Got the Maneuvering assist working
But no matter what I do the Park assistent won't work.

The car is 2020 A7, coded everything as in forum.obdeleven.com/post/76612/
The soft button works sporadically. Most of the time it says "Park assistant not available at this time.", other times it asks me to select the direction to park - I do this via the indicator stalk. Then press the P button and expect the car to start parking. The car will just turn its wheels slightly and then say "Process ended, please take over". The buttons seem to work for UNparking - the car will just move a few feet backwards and then again say "Process ended..."

Anyone with a similar experience? I am quite sure it is a coding thing but am also suspecting there is parametrization involved.

Anyone actually got it working without the Kufatec dongle?

If trailer hitch is installed:

My question is: is it normal the IPA icon desappear once the car speed is over 50 km/h ? I think it should be gray not invisible. once the speed is below 50 km/h the icon appears again in gray and it becomes white once the speed of the car is below 30 km/h.
The system works perfectly, it finds the space and it is able to park the car only pressing the button.


Hi
Your solution work for Q8 ? Is tested solution without errors ?

hi guys....I just received the kufatec dongle and the P button....I mounted the P button in about 45 minutes.....then I did the coding with the kufatec dongle but unfortunately no IPA works.....maneuver assistance works perfectly but IPA doesn't....my version of the zFAS is the 293....can you give me a hand? Do I have to write to them? I gave them the chassis number and they recommended this kit to me....now it covers obd11 I see that unfortunately mine is zfas 293...could that be the problem? and yet at USTOLLE it worked with the 293.....
