And this what photo of the motor? 606.912?
For me does not work itself sensor which it is led round by the red (on 606.964 same only under an intake manifold)?



Position 137 for the OM 606.964
Position 140 for the OM 606.962




Whether and there is no scheme for this strategy?

Ah, I understand now. It's a combination of 606.912 and 606.962.

I'm sorry, I can't help...

Evan, and about speech in posts 121-135 (page 9 of this theme)?
(I simply not so well understand )

Someone can applied all the same a similar technique only E300D (606.912)?

Evan, I'm confused as well. Does the block off work for the 97 606.912 n/a or not?

My intake is too dirty for only 100K miles, and the EGR is not cycling well on the highway.

The NA engine has no MAF, so there is nothing to fool there. The valve must remain in place and it must move properly, as its position is monitored by the computer. If yours isn't moving properly, it may be too late.

I'm not real sure how the .912's operate. I wish I could get a good look at one and do some tests to get a better understanding.

This is a great thread. I've been considering doing this mod to my car. However, I spoke with Oliver at Speedtuning today and he said that they now offer an "EGR Kill" ECU tune for $50. I'll be going with this instead of messing with all the wires and such.

You are best to get in a garage at more favorable temperatures or wait until spring.

Both wires are simply tapped into in the latest version I'm running on my car.



Pay no attention to the 2 extra inline splices from previous R&D work. There should only be the 2 "Y" splices.

Thank You KarTek, I see that you have contributed greatly to the EGR delete project. A very simple and elegant solution. Thanks

With clear directions I did the EGR delete this afternoon and no check engine light after a circuit around the block.

I know it has been a while since this thread was hot, but, I am working on this mod today. My question, is, after doing the diode & resistor mod, do I still need to install a blocking plate on the EGR? Should I remove the little piston inside the EGR housing?
Do I plug up the vacum lines coming off the transducer and the other vacum line that is attached to the EGR?

Thanks for reading.

On the non-turbo 606, which I believe has a similar EGR system, I removed the flap in the EGR body and disconnected all the vacuum connections. The flap in mine was attached to its axle by a pair of Phillips screws; I think this part was easier with the EGR body removed from the engine. The idle state of the EGR is zero exhaust recirc, so with no vacuum anywhere the exhaust valve should stay closed all the time.

I actually went so far as to remove all EGR vacuum tubing all the way back to the vac pump, because none of it serves any other purpose. Check the vacuum diagram for your engine to see if that's the case in the turbo as well.

If your state's inspection doesn't require emissions test for diesels, you can block the EGR port on the exhaust manifold and remove the whole thing, EGR body, valve, and vacuum actuators, and replace the EGR body with a rubber coupler or some intake tubing. Saves a little weight, reduces intake turbulence, and removes some unnecessary clutter from your engine bay.

Carl,

There's no place to put a blocking plate per se on the '98-'99 cars. Simply remove the vacuum line from the transducer to the EGR mixing chamber and cap the remaining open port on the transducer.

That's it!
