Since I replaced all the glow plugs on my 1997 E300D and cleaned the gunk out of the Intake manifold etc I cannot rid this car of the PO200 error code. It is so damn frustrating.

Does anyone know how I can get the more specific code > THe PO200 is generic and so far the only way to get more specific is to pay $129 and have the dealer put it on their computer.

Please anyone??
