I have had my 2024 992.1 911T for about three months now. Yesterday, for the first time, I got the "WBA limited" warning, and then it came on again today. I just got my car washed, clay barred and waxed the day before, so my guess is that there is some kind of residue over one of the sensors. I took a look at the front of the car but didn't notice anything amiss. Any idea which sensor or sensors could be the problem? Could they be somewhere else on the car besides the front bumper? The only assist option that I have is lane change assist.

Thanks.

 

This is the front camera by the rear mirror. Just clean it off.

This happened to me on my GT3RS but that was because I had a PORSCHE windshield decal on it and it was too big and covered the camera. Your manual talks about this.

 

Nothing to worry about. It’s one of those “quirks.”

 

Heavy rain and fog will also cause warnings (white warning triangle / message) in LCA (lane change assist) and other safety controls due to obstructed cameras and vision systems. These warnings will usually resolve by themselves when the weather improves...

ps Not a 'quirk' at all, but par for the course for cars that rely on passive optical safety systems only, and the reason why Waymo is a wild success because of it's LIDAR package.

 

My windshield is clean, and there is nothing obstructing the camera below the rearview mirror. Could it be another sensor?

 

I had the same error last year. I took it to the service department. The sensors in the mirror had to be recalibrated under warranty.

 

I got the "WBA sensor obstruction" grey warning while on the highway today. Clear conditions.
5 minutes later it cleared.

Where is this sensor really? I don't have a front camera to my knowledge.
