Yellow oil light

2.0 tdi brd pd170 yellow oil light has been coming on now for a while, oil is full every time. Today i took the cap off and the light went off which says to me pressure but the cap didnt blow out my hand or come off with force. Originally i thought it was a dodgy sensor before removing the cap. Could i have air in the system? Might be wrong but im sure this problem came up after a service , with oil change etc. No blue smoke and isnt running rough at all. No oil & coolant mix.

Have you changed the sensor?
Have you touched your vacuum pipes at all?

Did you disturb the non return valve on top of the rocker cover?

Sensor in the sump, cheap and easy to change when you change the oil. Opening the bonnet resets it. Mine used to come on about every 150 miles.
