How do you disable the EGR on E300TD?
 

Hi

Can anyone tell me how to disable the EGR on a 98 E300TD. Just had the intake manifold off to change the glow plugs and it is in a terrible mess with oily gue. I am led to believe that the EGR causes this. There are two little pipes going to the EGr but i have read somewhere that you have to do more than disconnect these pipes.

Help appreciated.

Thanks,

As of now, no one is sure. But my friend W140 S600 is working on it. Do a search their are a few threads on this floating around.

Disable the EGR and the computer will cut your turbo boost. Any solution will involve fooling the computer into thinking the EGR still works.

Any solutions anyone?

Get some scrap metal and fabricate a plate to block the flow of egr gases. About a year ago there was a long thread on someone who was going to have a large number of nicely machined plates made for members as a 'group buy'. You may want to search the archives and see if this would help you.

Check out the solution by "97E300D" in this thread. You could also contact him for additional details.

I had this modification done for the group for use on the 617 and 603 engines. Unfortunately it absolutely will not work for the 606 because the computer will know that there is no EGR flow. Do not attempt it.

There was a thread recently about this. Same model car and he blocked the exhaust side and channeled fresh air thru a small filter into the EGR.

One other person has successfully converted the computer control boost to pressure control boost. This thread was on about 2 weeks ago. Do a search on it.

On a N/A 606 getting rid of the egr is simple cut the tube and stick a K&N filter on it. The computer only knows that it is working not that exhaust gas is going through it. But on a turbo 606 getting rid of the egr takes a little work. As far as I know no one has done it yet.

See my comment above, and note the cars in my signature.

I've said this before on another thread: the bottom line is that the 606 turbo intake manifold simply does not clog up as much as previous engines did. Just clean it out whenever you take it off to replace glow plugs or leaky plastic fuel lines. In fact, last time I took mine off was 20,000 miles since the previous cleaning and it only had a light coating of soot. Not enough to even bother cleaning out, so I left it alone.
