Hi Everyone

I hope someone can help.

I have been changing the intake manifold on 2010 Discovery, and after 3 days fiddling, I put it all back together and its leaking oil from the back of the gasket (mustn't of got it on just right on install) so it will all have to come off again.

My issue though, is that I had to remove EGR valve motor to get fuel rail bracket out, and I just wondered if anybody knew if there is a certain way it goes back on, or do you just place it down and tighten up the 4 torx screws holding it there?

Many Thanks for any help

I hope I understood your question correctly. You did not removed your whole EGR, but rather only the black "motor" with the grey cap.... is that correct? If that is correct, the below may help.

I happened to have some EGR issues in the past. I was considering replace only the motor, or clean the thing first, but decided to change the whole thing. Sadly and expensively .

Coming back to your question:
- You should insert the motor slightly off-set rotated (don't remember which side) there should be only one way anyway since the motor has a spring rotation. It is kind of o locked to one side (EGR closed) It is that spring force that closes the EGR. Take the time the motor is off and spray some WD40 on the valve shaft and wiggle (rotating) the little bar inside... (it may prevent your EGR to stick open in the future)

- You then match the "double U" shaped insert from the motor to the "cross-pin" from the valve. Then fit and re-screw everything.

Tech for those wanting more info:
The reason is that the "motor" (not really a motor but rather a solenoid) has an integrated potentiometer to measure the position of the motor, therefore the amount the valve is open. The "motor" itself varies from 0% to 100% whereas when attached to mechanical part (valve itself), the movement is restricted from 5% to 95%. (I connected the motor only to engine and the ECU trows an error with exactly that message. I suppose the pin-"U" connection can fail, hence the specific error )

I hope it helps, let me know if it worked for you. If you need more info, I can make a video how to do it, just need some more time to prepare everything.
