Hi all! I have a 1.5 DCI K9K QQ J10. On Saturday she gave me an "oil level low" in the morning. A few hours later when I started her, she then presented me with "oil sensor error visit dealer". After this journey, I topped up the oil (it was low) but the error hasnt cleared. What can I do? Failing this, where is the oil level sensor? Can anyone provide me with a diagram so I can DIY it?
