I agree with Max as to changing your oil on your own, if you cant at least pick up a BMW oil filter or have the dealer change it. I have driven 3 BMW's over the 300K mark and maintenance for all have been minimum. I have learned over the years that it ends up cheaper to take your BMW to the dealer than to the indy. Yes, the individual indy visits are cheaper but I found myself visiting the indy much more often... The dealer has all the proper tools to read all codes and knows what preventive measures to look for... Since I change my own oil and do my own brake maintenace, I normally see the dealer once every year or two.

this has been my key to success with BMW, some can say I have just been lucky, but I have owned 10 or 11 BMWs over the past 20 years, and to not have a lemon in one, some part of my maintenace has been good. I had a few that nickled and dimed me for a period but that is when I started realizing that running back and forth to the indys was costing me so I only deal with the dealer now.
