Hi, I have an Octavia 2005 Elegance 5 door hatch

A towbar has been fitted

The reversing sensors don't give out a beep

I have checked the sensors by putting in reverse with ignition on - all make a 'click' or 'static' like sound

Has the buzzer been disconnected or turned off?

Where is the buzzer?

Is there a control box?

Can I get the buzzer to work despite the towbar?

Thanks

Beeper is behind the B pillar trim (can't remember whether it's the upper or lower part) on the passenger side. It's a small little thing and the connector can easily slide off - this happened on my car and prevented the whole system from working.
