First gremlin - front PDC issues

So... I'm coming from an E90 without front PDC, just rear PDC. On that car, it was an absolute guarantee that as long as the sensors were clear you could rely completely on the tone going absolutely continual when you were closer than 6 inches to an obstacle. Using that and augmented by the visual sonar display, never worried about hitting anything.

Now, on the G20 I noticed after perhaps the first week, I cannot get a continual tone on the FRONT PDC (seems to be fine on the rear!). When it gets super close, rather than going from fast beep to constant tone, it cuts the sound off entirely! It didn't do this always, but not sure what changed. No coding, no over the air updates I am aware of, no dealer visits since delivery.

It also is sluggish/unreliable to automatically turn on the front PDC view. Between cameras and the visual sonar markings, I'm in no danger of having an incident but I have to always remember to manually turn on the cameras when I am close to an object, defeating much of the purpose of having the system "watch your back."

Is this all working as designed? Any tricks I can do (coding or otherwise) I can do to improve the sensitivity?

Thanks!

Agreed with everything you said.

The front sensors are terrible and in the beginning, I curb-checked a couple of times when they didn't work as designed. And like you also said, the cam doesn't quickly turn on (or sometimes not at all).

My M5, also a low vehicle, has brilliant front sensors.

I've often thought that the M340i was a vehicle that BMW touted as their most tech-filled model, but functioned mostly as a beta test. Nothing ever seems to work perfectly all at the same time. Buggy as hell.

Sounds like something's not working right, my front PDC has a continuous tone when close enough. I don't have front camera though so could be different.

Thanks everyone! Guess it's a trip to the dealer! Will update this thread if I learn more.

No problems on my 330e, sensors working perfectly, and definitely the most accurate sensors I've tested so far, and it does produce a continuous tone when getting "too close" both in the front and in the back
