pACC function which is adjusting speed based on road (no signs) but on road like turns...etc. Now with 396 it is decreasing speed much more than before with 383 and it is kind of irritating me.

My radar updated from 383 to 396, pACC speed regulation work same as 383.

For me it changed to lower speed in certain turns on the same road.

RE: 2Q0 radar firmware downgrade
When I was upgrading from "2Q0907572J" 156 to "2Q0907572AA" 0396
Update Failed.
Bootloader was version 125, then I updated it to 0380.
Then I updated bootloader, and again tried update to 0396, and it was success smile
I think to downgrade you do not need updating bootloader.
You can just downgrade.

Have you write right Parameters?

I didnt changed parameters for 396 as there were not new ones. Are there specific parameters for 396?

RE: 2Q0 radar firmware downgrade
it is not the sw of the radar.. but the Navi data it get the speed parameters from.. i just updatet my navi card a few days ago. and there is some fron data in the speed parameters.. it now drive 30 kmh instead of 50 on some roads.. at the highway it can go from 130 km/h to 50 km/h ...is annoying .. but i dont know where to report it to.

It seems to be both, as when I upraded from 388 to 396 I'm pretty sure that I didn't changed anything else so this means maps were identical on 388 and on 396 as well but there was difference in regulated speed.
