Oh, the irony

Ill just add my recent trip up A1 for 250 miles. Had hardly any phantom braking problems until that drive, where AP was absolutely useless. So much I had to apologise to my family for how *sugar* the car was. How can it be so rubbish compared to other car manufacturers?

It used to be pretty much flawless until now.
 
Ok so this is odd, I disabled the AP Beta the other day in the menu and within 30seconds got my first phantom brake this year. Does TACC use the old stack? I enabled AP (sadly had to do it whilst parked) and it's been fine since.

So if you want to use TACC make sure AP Beta is enabled maybe?!?

I would think that the only practical difference between AP Beta and TACC is lane assist
