Random oil level warnings from trip computer
When I start up the car (156 JTDm, 54 plate) the dash computer runs through the startup checks and the other day reported an oil warning rather than the usual Check OK message.
It showed the oil as empty and displayed a 'Go To Dealer' message. A check of the dipstick showed the oil level to be fine. Next time I started the car it showed the oil level at max, the next time at half way, then empty again, then full etc. etc.
It seems to be all over the place. Is this something that's happened to others or is this likely to prove one of those glitches that proves suprisingly expensive to track down and cure?
Thanks in advance for the help.
