My wife's 2002 SLK-32AMG's BAS light is coming on daily after driving it for more than a 15 minute drive. I have a standard OBD to see if I can read a diagnositic code, but when looking under the dash on the drivers side, I do not see any connector that looks like the standard "D" shaped connector. Do I need to remove any of the covers under the dash? There is a port next to the hood latch, but it is not the shape that matches my ODB. Is this the port and Mercedes decided to use their own connector, or am I not looking in the right place. Thanks in advance.
