I had filled my tank just before I performed the mod yesterday, so I could get a true mpg result after the mod. Are ya'll ready for this?
Before the mod, I would occasionally get 30mpg, on highway drives and that was when I was being gentle on the pedal. I filled up today, after driving 45 miles. 30 miles of that was on interstate, using cruise control at 65mph. 15 miles of that included a good bit of pedal to the metal, performance testing.

Before the mod - 25 -30mpg
After the mod - 39mpg

Cost of mod $2.08 (Radio Shack)

Kartek, Thank you for your diligent research and effort on figuring this EGR bypass out.

Now, I need to figure out why my injector closest to the firewall is seeping fuel. I have replaced the leak lines with viton and still seeping.

You only covered a few miles, from what you posted, less than a tank... And the EGR won't make such a difference in regards to MPG's.... considering the EGR is active during idle....

But congrats!

For me, this journey started a couple months ago with a P0400 engine code, which points to a faulty EGR. I had taken the car to the dealer for that and a couple of other minor issues(fuel line leakage, which I ended up fixing myself.) The dealer wanted to replace the EGR. The price for a new EGR $1,200.00!! I chose not to do that repair.

After getting the IM off and looking at it, the EGR was all gunked up. I cleaned the EGR and the IM. The car did run a little better, but the mpg tests were all over the place. I did get 32mpg once, next test was 25mpg.
So, I think the EGR was faulty, maybe not opening and closing correctly. although, I did not get any more P0400 codes.
I check my mpg at every fill up and I have never gotten close to 39mpg before this mod. Also, the throttle response is amazingly better. From a dead stop to pedal to the floor, I reached red line rpm in about 2 seconds. (I didnt time it, but, that's how it felt.)

I will keep testing my mpg and let you guys know if that changes.

Only 606.910, same pump as 603. On electronic pumps, ALDA function is controlled by the MAP telling the ECU that it's OK to fuel...

Please can help me with this?
My car is S320CDI (y.2000)
I am electronics engineer, I know what it is diodes and resistor, but where to put it in my engine do not know

Just wanted to thank Kartek and the others who have helped on this project. I did the whole project in under an hour including the trip to Radioshack for parts and Advance Auto for the vacuum tube caps.

Question Thanks for this thread

Very cool and simple mod, which I hope to perform this weekend. Question: wiring up the components seems easy enough. What's really required for the physical EGR once the mod is in place? I know that removing it or blocking the tube might help air flow, but I'm wondering otherwise is there harm in leaving the EGR and that corrugated tube in place? Same with the vacuum lines?

-Chuck

Karlos, this is a thread about the OM606, not the engine you have. I would recommend finding a thread or forum dedicated to the motor you have. You might as well be asking for sewing tips.

nothing is "required" that is the beauty of the MOD. You can do nothing, remove it, what ever you wish.

"blocking the tube" does nothing for "air flow", the benefit is to no longer be scavenging exhaust gasses. Removing and blocking this portion of the system is of great benefit to the 606.

Removing the EGR valve itself will require some fabrication as the connector tube from the intake to the IC plumbing IS the EGR valve.
Some have removed and gutted the EGR, I am working on the "Fabrication" method.

To provide benefit to your 606, just block the flow of gases from the exhaust to the intake. What ever method you chose. As long as old spent crap from the post combustion side is unable to enter the fresh air side, you have performed a miracle. The lights will be descending from the heavens upon you.

Thanks, Mike (and Renntag). It seemed to me I could somehow fit something like a penny in there, in that corrugated tube inlet, and maybe using some epoxy putty to get it in to place, though we'll see. If I can do this electronic mod without removing the manifold yet again, that would be nice. I've found that the most difficult part is getting that crazy little round bracket back on that snugs the corrugated tube next to the EGR inlet.

I prefer to eliminate all related parts of the EGR system, thus simplifying under hood systems. Note, that as for the exhaust outlet, it is also possible to tap for a pipe thread and insert an allen socket style pipe plug. This ensures that you do not have to deal with the round clamp that is a PIA to manipulate.
