wonder if someone can help. A considering posting from my 2014 a1 to new a3 black edition and am wondering if the technology pack pro is really worth the extra money over the technology pack. I’m not really sure even from the website what beyond the comfort key and sunroof you get on top tha would made it worth getting. 
 

anyone’s expirience would be really bail. Much appreciated

Not experienced personally. You also get the 360degree camera for park assist, cross traffic rear assist and the warning for joining motorways etc, electric memory front seats. Worth a visit to the dealers to see for yourself. At the end of the day only you can decide if it is worth the extra £2.5k more for the pro pack. I find you manage without the tech until you have a car with it! Hence I installed the reversing camera to my edition 1 having had it previously and found it useful. 😀 

I have a 2025 A3 Black Edition Tech Pack,

The reason I never went Tech Pack Pro is because I don't really like sunroofs, bizarrely. Plus it advertises it as a "panoramic" sunroof.... it really isn't.

And it is just something else that could require maintaining :). 

The only item I would of been interested in is the electric memory front seats, but it's not a game changer in my view.
