Other than the dealer how do you get the codes from the computer? I called Advance Auto who said they would hook up there OBDII reader for free and give me the codes but it didn't see any.. It was a little pocket calculator sized thing that apparently only reads "check engine light" type of codes... I then went to the Tires Plus shop near my house.. They too offered for free to read the codes.. They hooked up a much more robust type thing to my X... size of a laptop.. again it didn't capture any codes...

Is the dealer the only place to get the codes read? I called my local BMW dealer and they want $130 just to tell me what the damn codes are...

Can one purchase an OBDII code reader on eBay, etc?

Thanks guys.
