Parking Aid Where is CPU? A6 Avant Quattro Estate 2010

[photon]

Newbie here!

Can anyone help me to locate the CPU for the Parking aid. Mine is an accoustic unit front and rear. I get the long beep and the flashing amber led in button when reverse is engaged or dash button pressed.

VCDS does not show any faulty sensors but indicates zero voltage for system,. Have checked fuses 3 and 4 in driver side dash panel. Both indicate full continuity.

I have read lots of posts on faulty individual sensors but my system is dead! No clicks from any individual sensor

Any clues anyone? Where is CPU for this part of system. Is this a known fault?
