EGR Bypass - What are the benefits? I cleaned out my EGR valve a week or so ago Havn't really noticed THAT much difference in pick up but the MPG seems to have improved slightly
after egr delete differences:-car drives better -more responsive to the pedal-uses less fuel -no longer requires periodic egr valve cleaning
the benefits of bypassing the E46 EGR valve, and how to actually bypass it. The method of bypassing in this guide can be used on the 318d, 320cd, 320d, 330d and 330xd, as they all use exactly the same EGR valve. (BMW OEM EGR valve part numbers: 11714701242, or 11717785452 from 2006 on wards). This post contains affiliate links.
After doing my work removing the swirl flaps and cleaning the EGR valve my car seemed to sort out its MPG problem but only for a day or two. Now i'm thinking it could be my EGR valve playing up and have looked on the bay and came across these
The pros are better fuel milage and maybe midrange torque. The cons: Illegal to mess with this stuff in most countries. Your car will fail inspection if they do an exhaust gas check. No "real" cons on the mechanical side. I did a EGR delete on my old E46 -02 320d and drove it for 100.000K´s with no issue. Same setup as this.
