Parktronic activates at random times

Somethings up with my Parktronic system, I disable it with the button and then every so often it activates again while im driving, it's like the voltage drops when possibly something activates and it causes the system to restart.

Has anybody had this issue, it gets annoying as the lights flash at random times :S

If I turn off my Parktronic while driving it will always turn itself on the next time I start the car. You are saying that you turn it off and it restarts itself while still driving? I never heard of that happening.

I understand that when I turn my car off, and then back on again i have to disable it with the button. However as i'm driving along with it already disabled, all of a sudden it will be on again and beeping (one of my sensors is dodgy so it thinks i'm about to hit something on the right side).

It seems to be that the voltage drops and the system restarts and turns back on again. Unsure what causes this!

That is definately strange. I would get a diagnostic run and find the right side sensor that is bad and replace it. Just one bad sensor is all it takes to cause havoc. It only beeps when you slow below 10mph right? Like pull up to a stop sign and it will beep when you accelerate?

Hey,
How did you end up solving the problem? I'm having the exact same symptoms!
