got home and checked my oil, as i'd topped up a bit ago and thought i'd keep an eye on it. came up straight away, no 2 minute wait message, and showed the gauge totally empty! left it a bit, still nothing, so i put a quarter litre in, got the 2 min message this time, and the bar cameup very low, topped a bit more and got it abut halfway, so i've ended up putting about 3/4l in, and the scale came up showing totally full - hoping i haven't overfilled? would it warn me if i had? can't see it would be critically overfilled but that guage thing seems to be acting a right stupid bugger. didn't get the "please top up" light as usual despite the guage showing zero so i don't know what it's playing at. anyone had similar?
