Hi,
my side and front parking sensors sporadically beep without any reason. They show as red on the infotainment and manouvreing brake is applied. The sensors are clean and undamaged (I actually went to replace them, but the issue remained). The park assist is retrofitted to a car originally having 8 sensors. I also suspected the sensor holders placement, so I removed old ones and glued completely new ones, with no luck as well.
What is the chance the the PLA module might be faulty and causing random electronic noise? Does anyone have experience?

When I remember correctly, front and side sensor share the second connector while rear sensors are connected to the primary connector with power and bus.
So yes, I can totaly imagine that the connector or the pins of the control unit are broken or something internally fried signal processors used for these sensors.
Is the control unit new or used? When used, does it have any signs of being a testing unit (Stickers, handwritten marks) It would not be a first that replaced and trashed units find their way back to markedplaces

Do you have a front license plate bracket? The non-oem ones that fight into either the tow hook or onto the plastic grill

Had almost the same issue when the local dealer mounted the license plate bracket way to high (almost 1" / 2.5cm" higher than the original position). I almost got rear ended twice at a red light due to automatic brake when sensor was on red.

I purchased the front mount from 3dgowest on Etsy. It specifically says it doesn't work with a license plate frame because of how close it to blocking the sensor. I was arrogant and did it way. What I would experience is the alerts going on during slow moving traffic, it would also alert for a few seconds if I was parking with something in front of the car. It didn't make sense because it wasn't always on but then I found out that VW compensates for this kind of issue. So you know how the sensor has bars that represent how far the object is? Well if you partially block a sensor it doesn't show that as "RED CLOSE" it shows it as "WHITE NEAR". If the sensor remains partially blocked, like in my case with the frame, it will alert until the car moves. Since the detection distance doesn't change as you move it realizes something is wrong and stops alerting. So like say people have snow covering their sensors, it's not going to keep alerting. You might have something blocking it permanently but think the sensor is broken because of intermittent alerts. This TSB from VW explains all the ways you can get false alerts static.nhtsa.gov/odi/tsbs/2022/MC-10210433-0001.pdf |
