Duramax EGR issues..
 

anybody have an LLY or LBZ with EGR codes or replacement issues?? finally had to take mine in today, they did the reflash and now it has as much power as a slant 6 Mopar... :(:(:( MAP sensor thinks i'm in Colorado... IAT jumped 50* all the time... I just went thru the same sh1t with my 2007 Harley and that was a 3 month mightmare... EGR light came back on HARD right after the update flash and now they have to replace the EGR and solenoid assy and none local in stock, special factory order.... and the dealers ONLY diesel mechanic just quit too.. just fvckin wonnerful

had an egr code at 8k miles, they replaced egr valve, another code at 23k miles, they re-flashed computer to make egr valve clean it self. There was no performance loss at all. I am at 50k miles now and that is the only issue I have had.

I unplugged mine and runs cleaner and better.

I have an '06 Chevy, Duramax, 4X4 1-ton van....I loved it so much I bought another Duramax van for one of my service techs. His EGR valve went first....7 hr job to replace it at the dealers.....last week mine went. The computer (at the dealers) said it needs replaced...there is a day of down time. But both computers were re-flashed last year, right after I bought them. Both are LLY's

check out www.pacificp.com egr blocker plates. or do a search here www.dieselplace.com look for a fingers stick nad egr blockers. kill them all the way.

i'm going out and unplug it right now... hell, the lights been on and off for 1 1/2 years, what have I got to lose...

I had the finger stick diode and block off plate done on my 06.

whats a finger stick diode?

it blocks the code from being sent to the computer, involves cutting into wiring harness. Finger stick is a brand name.
