Hi, just return from a trip from Belgium. About half way to Brussels and pushing the car a little, let just say I was keeping up with the BMW's & Merc's (just a tad fast) and cruising along nicely, I suddenly noticed that I was getting the " Check oil level" on the display. Within a few miles I stopped and checked after a minute and found the oil level a whisker away from the max with no visible leaks, water level spot-on and clear. Carried on with the journey and display had cleared, but kept coming back and going. Eventually I stopped again for 15 mins and found level up to max. I did purchased some oil and put a tiny little drop in (100ml). Message cleared and did not appear again for the whole journey and back. I did change the oil prior to journey with Genuine Vx semi synthetic and filled it what I believed was to the max. Could my speed have affected this reading? or does it have to be topped up to the absolute max? Anyone any ideas? :question
