Thanks for the replies but I don't think I explained my issue very clearly. I'm not getting a warning, its the oil level light 'blocks' that come on when you insert the key fob in the ignition that's telling me I'm low, only 4 of the 6 blocks lit up. I've checked it on the level in places I've checked it many times before so pretty level ground. I suppose I'm concerned it could be telling me I have a pressure issue if the oil level is OK, not sure how the level system works? If anyone has any info on this it would be appreciated.
