W210/OM606.962 EGR Delete
Hello can anyone help me I just tried this mod on my 99 e300td USA car because I put an egr delete in. I still have the old egr hooked to the vacuum line. Soldered the resistor and diode in and still get a p1401 code after a bit of driving. The ohm resistor is a 1/4 Watt 470. Did I do something wrong or do I have to cut a wire on the maff?
