My local auto store has been struggling in general for all Penrite oils.

2007 D3 TDV6. Been getting EPB warning coming up, both the dash display and the yellow brake warning light. Sometimes the park brake works fine and other times it will take a long time to come on or will simply go into the fault.
No screeching noises from the rear at all.

I did the park brake shoes adjustment procedure on the weekend but the problem still presents. Possibly the shoes are worn down too low and the EPB module if not able to pull them on that far and faults out or need adjustment within the module?

Code below, possibly the park brake switch?

Sounds like the switch itself has failed on the console.

I agree with Tombie.

The switches can fail.
It's a five minute job on a D3.

I am thinking that is the case, I will pull it and give it a blow out with compressed air and see how it goes. There is a lot of crud gathered down in that space.

I quite like their videos, I'll see if I can track a switch down and swap it over.

FWIW - Here's the write-up I did a little while ago ...

What did I do on my D4 today? Bloody nothing…

Lots to do and no time to get it done!
