Hello! One of my reverse parking sensors stopped working on my 2008 Octavia. The entire reverse parking system failed and when I put the car into reverse it emits a 3 second tone alerting to the failure. I was able to identify one of the sensors was not making a faint clicking sound as expected (thanks to this forum). I bought a replacement on ebay and fitted it this morning. But it didn't work. I now get a constant tone when in reverse and cannot hear any clicking from the new sensor. I used a multi-meter to check the wiring was receiving volts which is was. I just can't figure out what the problem is. Any ideas? Many thanks, Julian
