Howdo guys, your assistance please. Proud owner of 2008 4.2 V8. Went for a cheeky squirt today & whilst cruising along the motorway I had an amber warning flash up. (Low Oil level Add 1 litre) On stopping at the next services I checked the oil (changed within the last few months) the level was spot on, hasn't lost a drop. I imagine it's a level sensor fault? Is this common & if so does anyone know it's location? After restarting the engine the light has failed to return but I'd rather have it 100% reliable. I have my own garage business & therefore will carry out any tasks myself. Thanks guys.
