We have a C320. We have two conflicting oil test results and dont know the right level.
1. Manual test - following the method in the manual, oil level indicated OK
2. On a YouTube vide, an alternative check - holding the odometer reset button down, we get the following output. Oil level shows “-,- quarts”
Which one would be correct..? No oil warning light has come on yet.
Do we fill up or is the oil level OK per the first response?
Thanks
