2008 beetle dash light on with a aexclamation mark

Hi from uk this light is the tyre pressure monitoring system it is telling you that one or more tyres pressures are under inflation so! if you have not checked them weekly ? for your own safety you should may i suggest you check and inflate to correct pressure of all tyres inc spare ! obviously if one tyre is very low ? keep an eye on it? in case it has a slow leak/puncture ? ps the horse shoe is a low pressure tyre symbol ? best wishes from uk and merry xmas !
