I have a 2005 E320 CDI (Diesel) and would like to know if there is an Engine Oil dipstick available for this car, I do not trust the computer read out for the oil level check.

 

I have used the readout on the computer 4 days in a row. One day it tells me that it is 1qt low, the next day it tells me oil level is ok, the next day it tells me it is 1/2 qt low, the next day it tells me it is 1 1/2 qts low, the next day it tells me oil level is ok. And this is when the car has sat over night so all the oil has gone to the oil pan. With these kinds of readings is why I do not trust the computer. Again, is there a dip stick for the 2005 E320 CDI (Diesel) where I can see how much oil is in the oil pan???

 

See the dealer I they have a "test tool" to check the oil level you use the stick but it does not replace the red cap, they told me about $45.
I wanted one for the transmission as there is no way to check it.
