My on board computer keps telling me to 'check oil' and then it says 'visit workshop'. When I check the level throught the computer it says 'add 2 qts' but when I check the dip stick it's full. I even changed the oil and the exact same thing is happening.
I always use Mobil1.
Can anyone help me?

Thanks

 

Your dipstick provides the most accurate measurement. Whether an oil level sensor exists on a W210 E55 is unknown to me. It does on other models. Nonetheless, I would begin there. Good luck.

 

Your sensor is probably bad. The dip stick doesn't go bad. I think someone recently posted about their sensor.

 

Thanks. I searched but didn't find anything regarding the sensor.

 

lift it up, take off the plastic and look around usually it's bottom of the oil pan somewhere...

Try parts.com, they should be able to find you the right part. Not sure how similar the C class part is, but the linked thread should help you find where it goes.

 

Think with your dipstick Jimmy!
