2008 Mercedes A180 CDI
The car is a 2008 Mercedes A180 CDI
After driving 10 minutes or so have a warning of ¨Engine Oil Level Reduce Oil Level¨ is displayed. It stay on until the engine is turned off and off for 5 minutes. Then after driving 10 minutes again, it returns.
We took the car to the Mercedes dealership/mechanic and they believe the DPF isn´t being cleaned (for whatever reason) and that fuel passes through the cylinders to the oil pan and mixes with the oil which raises the oil level and deteriorates the oil as well.
They have also admitted that it could just be the sensor (in the oil pan?).
I am looking for a second opinion/get educated. Thank you.




Is this one of those engines without a dip stick? Sort of makes it hard to figure out what is really going on.




The oil level should not be above the last line near the "Max" marking. Keep an eye on it and if it doesn't make any radical changes, and the light stays off, I guess you can close the books on this one.
