Just took delivery of my C2S last week. While driving tonight, I got a WBA limited, camera system error message, which upon Google search refers to driving assist features. The thing is, my car does not have any driving assist features that I know of (e.g. brake assist)? It did disappear after about a minute though. Does this have anything to do with the front parking camera? My dealer installed my carbonio front plate holder incorrectly and it's blocking the parking camera and I haven't had a chance to reinstall it yet.

edit: just realized our cars DO have brake assist. "Warn and Brake Assist: pedestrian, cyclist and vehicle warning and intervention" - Does this mean the car will actually apply brakes if it senses possible collision? If so I need to tell my insurance agent for a discounted rate - I thought my car didn't have this option so I told them no.

This is a great question. I believe it’s standard on all MY22 cars. However, I can’t find a definitive answer as to what level of braking occurs…a “braking jolt” or a maximum braking response to an imminent collision. Here’s a thread about the subject from some folks more knowledgeable than me:

Day before yesterday my 2020 C4 started throwing "Park assist error. Inspection required but OK to drive. (Not exact wording). I have Surround View so cleaned front camera and sensors, but problem didn't go away. Pulled codes and cleared them and all was good for a day. While driving into shop this morning threw the same error, but just once in a 20-minute drive where when the problem first surfaced it threw up the error every 20 seconds. I am monitoring and troubleshooting and will report back here what I discover.

UPDATE: The issue appears to be related to cold temperatures. When going from a heated garage to outside with temperatures of -15 C or colder, it takes up to 15 minutes for the error to appear. Of note, the error only happens when braking to a near stop, and occurs even when there are no vehicles or other objects within 100 feet the sensors could read as obstacles. There have been no errors the past few days with temperatures above 0 C.

Bringing back this thread. Last weekend I got the WBA error message. My car is always garaged, and only driven in good weather. It had not been hose washed in a long time. So no debris or water on the car.

What causes this error message? Where are the sensors for WBA?

Thoughts?

sometimes it is the glare from sunrise or sunset blinding the sensor
