Hi All,

I've done some searching around and not coming up with much other than it's hard to diagnose and expensive to fix. I've been getting an intermiittent LCA (lane change assist) fault warning in the cluster and then the system stops working. It seems to come back on it's own after the car is shut off.

Anyway, I can't quite tell from the manual where the sensors are located. Looks like rear bumper. I assume it's not using the parking sensors, but could be wrong. It's a 2014 Cayenne GTS. Can anyone confirm thier location. Want to see if there are any lose connections or something needs to be cleaned.

Thanks for any advice.
