VCDS (Vagcom) throwing false errors?

[KudoWarrior]

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
Freeze Frame:
Fault Status: 00101011
Fault Priority: 3

01520 - Rain and Light Recognition Sensor (G397)

01229 - A/C Humidity Sensor (G260)
004 - No Signal/Communication - Intermittent
Freeze Frame:
Fault Status: 00100100

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

they are usuall pretty good, you could clear them and test again after a few days incase they was thrown by something like disconnecting a battery in the past.

My mk4 had the open circuit one and low behold the rubber around had worn and was letting water in the wiring.

Might be old codes mate they will still appear until you delete them ?

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.
