fuel injection flussh for carbon build up?
Hey everyone, I took my car in for a 30k maintenance today. SA called and told me my car needs a fuel injection flush for some carbon buildup. Something about having a 75% carbon build up. Im reading around the forums and i only found one other thread that seems even related. Is my SA trying to throw some BS at me? Looks like people are saying if you're using chevron's gas, the car shouldn't be in such a bad condition? Any advice or input will help. Thanks in advance. oh yeah, i drive an 08 328i.
