QUESTION: He entered radio code 13434& stereo code   U2728L2352
my care VIN # is 2HGES16335H010937

Answer
I need the code that was stored in your car's PCM.  You wanted help with your malfunction indicator lamp, right? I don't need the radio serial number or the radio's anti-theft code. Your mechanic cleared the code that was stored in the car's PCM (computer), I need that code.
