EGR Replacement 1998 ML320

Hi All, Is there anyone that can point me to some instructions for replacing the EGR valve. I would like to replace/clean it myself to save a few $$$'s but need some instructions.

What to be on the lookout for, catches and tips.

Thanks

Is there a reason you are going to replace the EGR? If you're getting an "EGR Malfunction" error, sometimes you can get away with just cleaning the tube that is inserted into the intake manifold. I did it a while back; took a little work, but saved big bucks.

Hi Roger

Thanks for the reply, I am planning and taking it out and giving it a thorough clean if needed. I know they tend to carbon up after a while, so I am just doing a ounce of prevention. My SUV has 80k miles on it and is still just purring along - touch wood.

RE: EGR Replacement 1998 ML320

When I cleaned mine I found it very difficult to pull the long tube out of the intake manifold because of the bends. Then when I removed the rubber vacuum block immediately next to the tube, I found that the rubber had deteriorated and the center syphon tube had broken off. Removing that block was the only way I could gain clearance and the right angle to get the EGR tube out.

The end of the EGR tube was totally coked closed with carbon. I am not sure how this can even happen.

I live in the rubber testing center of the USA and your mileage may vary. The part # of the vacuum distributor is 112-018-02-09, dealer price $9.25. You can reuse the EGR metal gasket but you may want to have this piece in hand.
