Ive had this before, now oil warning and then when checking the oil level was ok, so i started to ignore the warnings. A few weeks later the warning went on and i went to a garage to check the sensor, but on checking oil it was actually low. Last week i checked and topped up the oil, but not to the max as my topup bottle was depleated. Now the oil warning low keeps coming on randomly, but the oils half way between max and minimum. any ideas? Anyway to check senser with vcds?
