OK I finally Figured out the P0303 code. I did oil change few weeks ago and checked the oil for coolant and didn't notice any. Now I notice the oil looking like chocolate milk. So definitely have a bad head gasket, hopefully the head is not warped or cracked. Now I called a few shops around here the does BMW and they all range from $2500 to $3500. Is that the going range in northern California? So I bought Bars Head Gasket coolant sealer with carbon fiber for $65, I put that stuff in yesterday and am going to finish of the last procedure today. I will let you guys know how it works.
