After most recent updates: ACC disables itself.

After the update to R63, the LKA update, HVAC update and other stuff ACC simply stops working. It happens only when it is dark and it is sudden.
Because I'm often on motorways, it only happened there. It also means you all of a sudden see a significant speed drop.
If you looking in your mirrors to overtake, this is a freaky experience. Same if you are stuck in a train of cars behind a truck....

Before, I did have sudden unnecessary speed drops linked to the ACC (tested it with AEB off), but those were cured after a spring 2024 update.
Now, there not so much a braking moment while on ACC, but it simply stops (icon is no longer green). Regen causes the speed to drop quickly.

Anyone experienced this? Was it fixed?

I had never an ACC disconnect, TJA sure, even before the sc077 update. But it had always reverted to plain ACC. Maybe the steering wheel switch is faulty and sending a disconnect signal?

Can you connect via car scanner and post the list of DTC of your car?

No scanner available Nanomad.
Did not consider the switch as a cause, because I never experienced it. Day one after the updates it popped up.
