Sensor. pick up pipe blocked. ok mate is that a serious fault? says oil level in manual but level is defo to the max now.
hit the search bar and you will see that its probably the pick up pipe the book says my car will do 500 mpg dont believe everything the book says mate
mine was the same mate even had new oil change but aint gonna sort it if the pick up pipe is blocked take off the sump and unblock it for the sake of such a simple task it cost me a new engine and if it needs a new pipe they aint to expensive and could save you a few hundred failing that its that then i would start looking at sensors one on the oil breather filter is a good start as it is easily disturbed
mine didnt it just stopped altogether resulting in seized enginge
