VCDS (Vagcom) throwing false errors?

So I visited my mate who has VCDS last night and thought I'd make a few tweaks.
After i was done I decided to do an Auto-Scan to see if there were any errors...wish I hadn't!

Got a bunch:

Whilst reading them I realised that some of them couldn't be an issue as the feature was working fine (as far as I can tell).
For example:

3 Faults Found:
02070 - Rear Parking Aid Sensors
011 - Open Circuit - Intermittent

I know it says "Intermittent" but I wanted to know if there was any way for the VCDS to throw up false errors depending on conditions?

I have the full list of error codes I got here: https://drive.google.com/file/d/0B90mX-lJ4my9Q2JMWGJxTFVhYmc/view?usp=sharing

Cheers guys. Good point @antowens

I've cleared them anyway and will retest again in a few days. Hopefully the list would have gone down a bit.
