Hi, I am a new member and this is my first post. Don't know what the protocol is.....so hi! I bought my Mercedes this January, a W203 C270 CDI Auto Avantgarde and I think it's great! Anyway, I'm about to do an oil and filter change myself this weekend and need some advice on getting the dash to display the actual oil level rather than just 'Oil ok'. I've researched as much as I could but the procedures I've found (ignition position 1 then pressing the reset button quickly 3 times etc) hasn't worked. I'm just a bit worried that I won't be able to accurately check the oil level after I've replaced the oil. Unless I just do the 'count them all out and count them all in' way and simply put back the same amount of oil as I've removed? Any advice appreciated. Thanks!
