Temporary low coolant

[goodbuzzman1]

So twice this week while driving, the low coolant warning has come up.
Both times I have pulled over to inspect and sure enough the coolant level is below the minimum. I unscrew the coolant reservoir a little until it hisses and releases the pressure and like magic, the coolant level rises back up to where it is supposed to be.
Does this imply that there is air in the system?
Has anyone had similar?

Possibly. These are notoriously difficult to bleed properly, try leaving it ticking over with the cap off until it gets up to temp. Top up as you go.
