Parking Sensor S7 lost Comms

[TheD0nn]

Hi All,
I've been having a problem with my Parking Sensors on my Model 3 Performance. I keep getting a Parking Assist Unavailable error on the screen and when I enter the service mode I can see Sensor S7 (Outer Rear Right Side) has lost comms. I have therefore checked to see if it is the sensor by swapping the left side with the right side (Both have exactly the same model number) and expected to see the Lost Comms move to the left side, but it remained on the right side. This would indicate that the sensor is in fact ok. I also bought a new sensor and that didn't work either.

Do you have any idea what it could be? Sounds like a wider issue which is concerning.

Cheers
Lee

I'm going through something similar, except ALL my sensors have lost comms. Now to be fair I just put them on a new UP Fascia, and may have some adjustments to do regarding being exactly level with the fascia. I've taken the stock fascia off and on many times and never had an issue before.

I'll try to update as I troubleshoot. I've already tried both "safe" computer resets. Yes my fog lights work so I don't think it's the main connector.
