Low voltage error on Instruments (17)

[HPsauce]

I've never seen this before on a VCDS scan, even when I've had battery issues, which I haven't at all lately:

Address 17: Instruments Part No: 4D0 919 035 BA

1 Fault Found: 00668 - Supply Voltage Terminal 30 53-10 - Supply Voltage Too Low - Intermittent

I've cleared it and will see if it returns, meanwhile any thoughts anyone? And what is Terminal 30?

T30 is battery +ve. Quite common for modules to log that when the battery is disconnected. I wouldn't worry about it.
