Hi guys
Thanks for the feedback, the first thing I checked was the oil level on the dipstick and it was at 3/4 between min and max on the dipstick and I had provided the garage with 10 litres of oil and got 1.5 litres back. So I know the engine has the correct level of oil in.

The oil level sensor was changed because this fault was appearing before I had the oil change, so this is the reason a new one was put in, but I am still getting the same display on the dash.

This only seems to happen after the car engine has got warm, for example if I turn the car on and off several times whilst it is cold the error message doesn't appear. Only seems to happen after a journey, and if I do the same thing (off/on) several times the message displays.

The other strange thing is that no error codes are shown when the computer is plugged in......!!

Any other suggestion?

Cheers Andy
