Hi Everyone and welcome to this easy ‘Do It Yourself’ tutorial.
Here I will show you how you can clean / change EGR valve and air filter on 3,0d inline 6 engine. You can apply this tutorial on all vehicles with similar BMW engine (530d, 330d, 730d…).
Dirty or false EGR valve can be a cause of a lot of problems. If your BMW is periodically slowing on acceleration, producing a lot of smoke, giving you engine warning lights or similar, one of the first things you should check is EGR valve.
Also you can bypass it. Please mention that in some cars bypassing should be also done electronically.
Here are the links for EGR valve for BMW e39 530d:
Cleaning Spray: Liqui Moly 2033 Pro-Line Intake System Purge, 400 ml
It is easy to change or clean it. In my cause I was doing yearly maintenance and just cleaned up EGR and replaced Air filter. Your BMW deserves a lot of fresh air.
Now it’s time for work
First step is to open the hood – get in the car and pull out small plastic to release…. just kidding 😀
(you can click on the photo to enlarge it and see captions and comments)
You need to remove 3 torx screws with H3/16 screwdriver
Remove the front plastic and also remove one screw on top of the white plastic (with BMW logo) and remove it.
Now you will see EGR valve and you will be one step from removing air filter
First release the screw on the large pipe and take it off from EGR
Next remove 4 screws from the corners of EGR with 10mm and disconnect small pipe from the top of the valve
Now release the clip on the screw and carefully spread the clip so you can take it off from the connect point
If you have done all the work, you should be able to remove the EGR valve
Mine was not very dirty as it can be. You can clean it, change, or bypass it. It’s all up to you.
When you’re done you can bring it back on the engine end start with air filter removal.
Now remove those few screws including big oil cap. After plastic cover removal you can bring back oil cap.
Take this dirty Mofo and throw it in the trash
Insert the new one. I bought some mid-class air filter for about 50$, later I am planning to replace it with some sport KN filter.
We’re almost done. Now put back some plastics, take the beast out of garage and use this compressed air bad boy to blow out all the dirt and dead mosquito’s 😀
That’s it my friends. I hope this helps you. If you have any questions or suggestions leave a comment.
