D2a parking assist beeper?

Any ideas where it is? It's not beeping, so i'm assuming it's faulty and needs replacing.

[It'sNotWorthComplaining!]

I think the control unit is in the rear pillar behind the rear pillar lights.

Ya. Found it in the lhs cavity behind grille inside rear doors. Hard to get to mind you!
