I have PDLS+/LED lights on 991.1. High beam Assist worked great for the first few years. Live in a very dark area now and when activating the High Beam Assistant by pushing the turn signal forward, the Circle A comes on as usual but no bright lights. About half the time I will get the warning in the picture below after about 30 seconds. After a few minutes, the warning will go out and the High Beam Assistant functions normally. Anyone seen this? I'll have the dealer look at it next month, but interested if others have seen this.

 

Is your windshield clear? The camera lens might be getting blocked by dirt or etc. it's right outside the rear view mirror area.

 

It is...I run my windshield wipers/washer as a first step to ensure it's clear.

 

Any aftermarket electrical mods? Like radar or lazer jammer?

I'd say your camera is going out/failing.Still under warranty?

Wonder if this is a sign your batter is starting to fail? Lots of eletrical gremlins with old batteries.

 

No mods.

Car CPO until March 2020.

Battery is original from March 2014. I keep it on a tender whenever its not in use.

I'll have it checked next month at the dealer.

 

Glad you have the CPO.

Please follow-up next month. I have the LED with PDLS +, so I'd like to learn, too. Thanks!
