bmw air filter change egr agr valve repair

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.

“EGR works by recirculating a portion of an engine’s exhaust gas back to the engine cylinders.” Source: wikipedia: Exhaust_gas_recirculation

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:

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 😀

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 😀
