I got the emissions recall G30 for the replacement of the oxygen sensor module and ECM reprogram. Has anyone else had this done yet and noticed any difference in anything?

 

I think people said their overhead MPG reading was higher.

 

Sweet! That would be nice!

 

my gas mileage went up a little after i had it done, but i am still in my break in period

 

First off people should verify if that had previous flashes.
AC,AE,AG,AO.

Then there was the AU which everybody luvs because that was the big fix but people say different stories on better and worse MPG cause you get more regens.

Then the latest as of Nov 15 is AV which is now part of recall which is a tranny reprogram just like the AG was.

So if your gonna start another recall thread, please be more specific on which versions you had not to mix anybody up.

To find out which version you have, pop open your hood and look at fan shroud/subframe area and look for the stickers. I have 3 on mine. AG, AU, AV.

My truck is never unloaded so im always seeing 8-9 mpg. I have 31k on her.
When I first got my truck. I can do 600 miles on hwy unloaded cruising at around 65-70mph. I would luv to do that again to see if my mpg went up, but unfortunaetly, i dont get paid to drive empty so that would be a waste of money and time.

 

The build date of the trucks having problems is of interest to me. I haven't bought a 6.7 yet. Thanks.

 

Had the G30 done 12/3/07 this was the first, didn't drive but around 6 miles back home, could not tell if it improved any thing or not, would be nice if it did improve the mileage.

 

My truck was built in 04/07 and I bought it in 9/07. I told them to do the latest flashes when I bought it. The sticker on the radiator support just says (updated ECM) along with the date and dealer code.
