E46 Engine Sound Problem
I noticed lately that the sound of the engine is unusual, it's kinda high, I don't think it was like that a couple of months ago.
I have another problem, that might be connected to it; I keep getting the sign telling I need to check the oil level showing up seconds after I start the car, even though I had changed the oil a couple of days ago and the oil level seems good, I had that sign showing up for a while now; since about 3-5 months; the first time it came out, I think I had had about 5-7k miles on the car since the last oil change ( which was done at the dealer), so I added some oil because it was kinda low, but the sign kept showing up when so after few k miles I did an oil change myself, and it wouldn't stop showing up, so a couple of days ago ( after 3-4k miles) I did another oil change ( w/out changing the filter this time ) and it still shows up at the start up; the car might be consuming oil but not like crazy I think.
anyone has an idea of what's going on with the car, or why the engine sound is high?
I was thinking about taking it to the dealer to see what's going on but I though I can ask her first.
Your help is very appreciated.
