Hi,

I've got some electrical gremlins on my A3 1.8 8L 2001.

Dash is going nuts with dials jumping back and forth and lights flickering. Vagcom gives numerous faults with central locking, but I'm thinking it may be brake circuit related as it started with esp light occasionally coming on and off with the brakes ramming on.

I can't post all errors right now but the ones i think i should investigate are the yaw sensor fault and primarily the brake system.

But what caught my eye from measuring blocks was these two values jumping on and off which seems to coincide with the dash going nuts.

And flashing dash

I'm just wondering what the first steps should be. I'm also wondering if this could be caused by dodgy power to the dash?

Or perhaps its the abs module although I'm inclined to think not

Thanks
