a good scanner

[rmuntan]

I have been searching the threads for a scanner for my 05 x5 4.4 with 106k on it. It just gave me my first "check engine" light. I have have limited experience with scanners, I know allot of questions need to answered.

I do not know what the hell ANY scanners can do....I have read several threads and see people post the different types to use and for what.

I know I hate seeing that amber light glowing at me (or my wife for she is the one driving it). I have read that it will through a code when it does the same thing a couple times in a row.

I do not know what I can do but seeing what may be causing it could help. I can change plugs and wires and check for leaks but for fuel mixture and air flow sensors.....I guess I need to have that looked at by a professional so I am not just chucking money at it thinking I can fix it just because I have a scanner.

With that being said, any help telling me the difference and what they can do will be helpful.
