VAG com ABS Brakes voltage supply problems

[Defratos]

I got back to the UK a few days back, and yesterday I drove my S3 (its been sitting parked up for like 4 months now). I had to jump start it, but that was it. It was driving fine until I got next to my house when the warning light and ABS light switched on so I parked the car at the house and ran a vag check. I got the below error message.

Address 03: ABS Brakes Labels: 8N0-907-379-MK20-E.lbl
Part No: 8N0 907 379 E
Component: ESP 20 CAN V005
Coding: 18448
Shop #: WSC 01236

1 Fault Found:
00668 - Supply Voltage Terminal 30
16-10 - Signal Outside Specifications - Intermittent

Now I've checked my ABS brakes fuse but its working fine. Anyone know what this error code could be?

I'd delete the code and check it again.

Most likely due to turning the ignition on with the battery flat.
