I am 600-700 miles since my last dealer performed oil change. Since that service I will get the "red reduce oil level" message on the display at random occurances, but only while interstate driving. After you clear it, it will not come back until the car sits for a while and sometimes appears on the return trip only one time. I check the oil level between the trip using the buttons on the wheel and it always states "oil level ok". The red message will not appear when driving rural and city driving. It will not appear every time on the interstate (3 out of 5 average). Does the stationary oil level check use the same sensor? If so, do I have a faulty sensor?

 

Nobody else with this issue?

 

I don't have a diesel, but I suggest you
a) Get a dipstick and check the level directly (or get your dealer to
b) read this thread and see that indeed a sensor can be the issue:

My guess oil sender unit (sensor) may need replacement current part # is 0061532828 to comparison shop parts.com $142.80

 

Thanks guys.

 

Mine did it also after a oil change had 1 pt too much oil. I used my extractor removed a pint and all was well. Sensor worked problem was too much oil.

 

Vettdvr,

Would the red message appear only on the interstate with your car and did the oil level read ok when checked on level ground?

 

i have the same problem, that was after a mb tech changed the oil and sensors.... but mines only pop on trips 20+ miles
