EGR delete on 98 e300td , now PO100
I completed the EGR delete last night as described on the forum, the KarTek method,and now I have PO100 code which I didn't have before???
Does anyone know what can cause that,I see that this method has been done many times successfully.... My luck... |

Year and model would be helpful.

So I just disconnected the diode-resister jump across the green/grey and yellow /white and PO100 cleared. PO 400 didn't come back up but it normally does after I drive it a few miles.I'll take it for a drive and see what happens,with the EGR vacuum line disconnected it will probably throw the code

Hummm...
I drove her for awhile and no code??? I'm going to go drive 250 miles tomorrow, we'll see.. |

Hi, I got your message. It's good to post this stuff here as you have done, to aid anyone who might also have troubles.
You mentioned in the PM that you have done the "three step" process. So, are you using 2 resistors and a diode? If so, you need to disconnect the EGR transducer and cap the vacuum line output of the transducer. If you do the 2 component process, you leave the transducer connected and again, cap the vacuum output port.

Thanks so much for your reply and help.
I did the diode,1 resister according to your revised schematic and then capped the EGR valve output and put a plug in the hose that goes to the EGR itself. Since I sent the PM last night, I pulled one spade out of the tap splice and the PO100 went away. I've driven it a number of times today with the EGR valve still capped and it hasn't thrown a code??? I have a longer trip planned for tomorrow,hopefully it will be OK |

I went far my drive today and 5 miles into it I got PO400
So I'm back to trying to figure out why I got PO100 after doing the 2 step EGR delete.I followed the revised wiring and sounded out the pins to make sure I had the right wires. The only part I wasn't sure of was the direction of the diode,I put the white stripe side towards the resister,I had seen a pic of that but not sure if it is correct. Any Ideas??? Help please Evan or anybody who had the same problem with the delete |

The white stripe needs to be oriented towards the green/gray wire. It doesn't matter which side of the resistor it's on.

Yea, that's it I'll bet,the strip is towards the resister/yellow-white.
I redo tomorrow It was a long 276 mile drive though the mountains in limp mode!! I'll let you know, Thanks Much!!! |

Well I re installed the resister/diode with the diode in the right direction and have been driving around town today all day and Wala NO code !!!!!
I'll wait for another day or two of driving before I break out the champagne... |

Update..
I drove it for over a day and no codes,then all of a sudden yesterday on cold start I got a PO235 code,"turbo charger boost sensor", then again today on cold start. I reset the ECU after it warmed up and then it was ok during the day until the next morning on cold start. ???? |

I'm assuming the "boost sensor" is the MAP sensor located on the inside of the fender on the left side. It has a short tube that runs to the side EGR mixing chamber. Check and make sure you didn't disturb or damage the wiring to it and that the tube is attached.

Here's one for the books....
So I checked the lines and wires again and all OK Took it for a drive and under heavy acceleration with no boost, PO 243 came on So I started to check the waste gate solenoid, wires, vacuum lines and found a mouse nest down under the brake vacuum where the thin white tube gets the vacuum for the turbo waste gate, low and behold the mouse had chewed a large hole on the line,I put shrink tube over it and went for a drive,WOW I now have a race car!!! Hopefully this will be the end to all the check engine lights I've been getting! |
