Parking sensors

[sainte986]

Is there anything I can check on the parking sensors as they sometimes work, other times don't. When you put it in reverse it does the beep and then the sensor button/light flashes when it's not working.

It has front and rear sensors.

Help please

Plug it into vcds and it will tell you if any of the sensors are faulty.

Also check the grounding of them, this sometimes is faulty and causes intermittent errors
