Front Parking Sensors

Not sure if I have posted this one before. The front parking sensors are always active -unless you press a button on the dash. The rear ones only become active in reverse gear (and also if the button hasn't been touched). The button resets if the ignition is off/on. There is a danger you switch off the sensors for the front -and forget that the total system is off. A few close calls with that so far.

The reason to post is the sort of false alarms you get with the front sensors. I notice the front sensors are activated by other vehicles in traffic. I am not sure if it is air wave - or water spray - because the vehicles don't seem to come that close. Strangely the vehicles that seem to cause the most problem are motorbikes (maybe they are closer) and then trucks/buses. Cars don't tend to set off the sensors. If you are in queue - the sensor can be pinging away as a series of trucks drive by.
