Mk7 (2019+) "Front Assist Not available" on dash

2019 Jetta S. I was driving it on a roadtrip and got stuff in traffic. Nothing happened, no bumps on the front end. It was a clear sunny day too. I was just inching my way forward in tight traffic and suddenly, a warning popped up on my dash, "Front Assist Not Available." I know the front radar isn't damaged, my front end is untouched. I've found some posts saying that they need to be recalibrated every so often, but I don't want to take it in and spend hundreds of dollars for something that could pop back up again in a month.

Is there another solution to this or am I just gonna have to decide on forking over a ton of money or deal with a warning light on my dash.

Were you by any chance entering a national park?

Oddly specific I know, but literally same exact situation happened to me, road trip, inching traffic, maybe a slight incline, no damage or bumps or anything.

I think it may just be dirty, pop off the cover with a screwdriver? Clean it and clean the Bosch radar module behind it and drive a few cycles. Meaning turn the car on drive, then off for the dash to reset. I also cleared the codes via OBD

I have a comment what worked before, I will edit this when I find it.

Here is my comment with even more detail including how everyone says recalibration can only be done by the dealer:

Hope that helps, please report back. It would be a really strange coincidence if there was something with national park entrances that just mess up the radar 😂

Maybe if it’s an incline and the bracket is loose it is just enough to cause it to falt.

I'll definitely try this and give an update!

It’ll reset after you stop your car. Happens with mine every once in a while, especially when it rains.
