Distance Warning Going off 2014 E350

Hi, I've been getting an intermittent Distance Warning and got the car scanned via Star Diagnostics (XENTRY) and the following codes appeared. I'm not 100% as to how to remedy this.

You'll need to photoshop these pictures for closeups, so that we can actually see what you are asking about. Right now, I see nothing.

B29/5 – start by checking rear, right radar connections/sensor.

well the problem has nothing to do with the Blind Spot assist. It has something to do with the ESP module, the shop I went to explained the pins for the ESP module add reading that the data produced isn’t plausible. And that’s the reason for the fault. Any idea konigstiger? A bit confused.

Its stating that No CAN message is being received from the ESP control unit

and that the information received is implausible from the Traction system control unit.

I can be wrong (no expert by any means) but thought it best to start simple since problem is stored for b29/5 sensor, harness/connector/sensor is readily accessible for inspection. My reasoning, if a control module registers a fault, the control module can then transmit a signal informing that its information cannot be trusted. See attachment to inspect ESP unit.
