Where do you find the connection to connect the computer to have it read what your engine lights mean? I'm going to auto zone today to use their computer to see why the "check engine light" is on in my car so I figured, I'd take the sprinter in at the same time and hopefully I get a code that will support my arguement that it is the EGR valve.
At this point, I can tell they don't want to spend $900, so they want to waste time diagnosing other problems. When I told them yesterday about the new symptom, they told me to take off the battery connections, leave them off for 20 mins and clean them real good.
I just don't want to waste a day of them diagnosing my problem and then another day for them to decide to fix it and another day to do it.
So how can I find where to connect the computer to?
