I'm running through the list of possible causes for the engine warning light and above code to be displayed.
Ive changed the oil, no change, the OCV seems ok.
Not stuck, dirty or gummed up. Works with 12v across it. Another cause is blocked Oil Control Valve filter. Has anyone tackled removing the filter with the engine in situ.It's below the OCV behind the alternator, both pretty inaccessible on the Mk3.
comments, thoughts, past experience welcome gaining access to the filter with the engine in place
