Checking oil level on '07 X3 - cluster indictor confusion
I have an '07 X3 with the 3.0Si engine and have gotten conflicting information from (3) different Bimmer dealers on checking and verifying the oil indicator readings for engine oil level in the instrument cluster. (BTW - I think BMW is nuts not putting a dipstick in)
Anyway, drove the vehicle for a while to be sure it was up to full operating temperature, and while it was still running, pushed the button in the cluster on right which is next to the trip reset button. A display pops up for oil level and a bracket begins to move from left to right. After a few seconds it stops moving, then disappears and the only thing that comes up is an "O" to the right of the oil level bar graph.
One dealer that looked at this in operation told me that the "O" displayed means that I am down 1 quart and I should add a quart and recheck it. Of course they offered to put their overpriced oil in, however instead I went home and added 1 quart of 5w-30 synthetic, started the vehicle and rechecked the level indicator. Same thing, same reading, just and "O" is displayed after level check cycles thru its paces.
This is where I am now confused. Reluctent to just start adding more oil, I decided to check and research on the net. One site indicated that the "O" means that the oil is overfilled. I hope not, if thats the case I was already overfilled and added another quart based on the dealer's advise!
I then called (2) other different BMW dealers and got different responses from them. My understanding is that once the bracket stops moving it should stop somewhere on the graph to indicate where the oil level it is at, and additionally if its at a safe level an "ok" should be displayed. I get none of this, the moving bracket disappears and just the "O" is displayed.
Before going through this process, and possibly adding an illadvised extra quart of oil, I had NO oil warning light, either yellow or red. (another dealer told me I would get a "yellow" oil light if I was down 1 quart and a "red" oil light if I was down 2 or more quarts) Since I have only had this vehicle for a few months, I was just concerned about checking the oil level to be sure.
So, here's the question: am I still low on oil, am I way overfilled, or is my oil check indicator malfunctioning??
Also, does anyone know of, or ever heard of a way to add a dipstick on this engine?
