anyone know where the parking sensor ecu is on an 06 octy hatchback?

On a 2010 it's behind the passenger side boot liner on the rear wheel arch.

I’ve got a Skoda cd changer inside a sort of compartment. Is it to the side of that behind the liner?

The info is on here if you search.

 

If I recall it's in the passenger side lower B pillar, but don't take my word for it.

Yeah it's behind the boot liner on that side, literally on the metal of the wheel arch. Can't miss it.
