ABS / Christmas Dashboard Lights!

Hi There,

After doing some good long trips, had an error pop up on the weekend away.

Beep ! P all sorts of lights flashing, party mode engaged

Car drove fine. Stopped at some point. All clear, maybe 10 miles and same thing.

Have since plugged in my ODB11 and cleared everything down and drove to work and back and it seems fine.

There was and ABS Valves voltage Supply - 01200 code in the Brakes module

Though to be fair, the Brake Module has ALWAYS had a Control Module fault - I believe scanning it can create a permeant false fault and ~80,000 miles on, it's not been an issue, though the ESP button on the silver bar has never done anything

I believe the front pads are getting lowish, but I don't THINK that's the issue. I've new pads and would have swapped prior to the LONG road trip, but they came in late - Rears were done a little while back, though I know the EPB can be a fussy thing, but don't think that's it!

Same error here, '07 S8.
Curious to find out if it's the ABS wiring loom degradation, the Bosch 5.7 brain, the input voltage (terminal 30 reads quite low in most modules) or something else.
I did manipulate the abs loom a bit recently, it's under the left hand front fender, I wanted to inspect the pneumatic line for the air ride.

I did the brake pad swap and was good for a week, then JUST before going away got the same error, indicating that they were not a factor. Honestly I didn't expect them to be, but was a reasonably easy thing to do and rule out.

Cleared it and it's been good for a few weeks now.

We've had a LOT of dry weather, so I'm wondering if it is weather/damp/corrosion related.
