EGR valve unveiled and some repair ideas.

[retepsnikrep]

I heard back from him he said it worked in the car but he took it off when he sold car.

I'll try it in next few weeks.

I have said before on this forum:

Break into the sensor section of your EGR valve.

Carefully take the retainer clip off the wiper.

Remove the wiper, and bend the two arms (not the fingers!!!) the other way.

Now your fingers will be facing AWAY from the carbon pads when you reassemble it, which won't allow your 'sensor' to wear out.

I bought a new EGR valve, and before installing it onto the car, performed this mod and I haven't had ANY issues with EGR since, and probably never will! I also added a nice blob of contact grease on the carbon to be sure it lasts forever.

For the two silver connections that cannot be easily reached. You used a scalpel blade to cut them. Once they are cut, do you re-solder them back on or you just leave them disconnected? I saw one where they were bent together and it was shorted. Can you explain what this connection is used for?

Thanks

If you're talking about the two connections that the metal posts rip out of, then YES, you need to solder wires into those holes to remake the connections. Those holes connect the pins in the top connector to the actuator coil. Without those, your engine light will trip every time.

Finally got round to fitting the modded RS Pot modded EGR Valve to my project car seems fine at the moment.

Took the modded valve off and replaced it with a brand new EGR as going on a long European trip in summer and don't want a failure abroad. Seemed OK though which was good.

Hi Peter,

Are there any more details of this internal repair?

Drawings etc?

There are some rough sketchs somewhere but might take a while to find them.
I recommend flipping the standard egr pot contact points or buying a new one.
