Glamis, the reflash for level sensing problem a multistep procedure.

The condensed version:
Drain def tank.
Reflash number one.
Fill def tank.
Reflash number two.
Using TechII verify that tank sensors are all 'active' and that calculated range is greater than xxxx.

Mine has been done twice (difference versons of the update and at different dealers as the truck was on the road the 2nd time) and have not neither charged for def.

Fuel mileage has improved with odometer mileage.

Just talked to my service manager after he had discussed the high EGT issue with GM, and they confirmed that with the new flash they are injecting more fuel at the cylinders to raise exhaust tempretures. This change was mandated by the EPA after their testing indicated that some of the vehicals were not meeting the new emission levels after the trucks were in service for a period of time. Guess they have the power to revoke the certifications as they see fit.
I voiced my concern that from what I was seeing now (plus 200 to 250 degrees), that towing would very likely be as high as 1750 under some circumstances; ie mountain passes, based on prior experiences towing with this truck. I asked if we could re-install the old programming, and after talking to his tech, said that the old programming could not be recaptured.

DO NOT have this reflash done; it cannot be reversed!!

You don't have a choice in California, you can't renew your tags until you get the recall done

OK, My question on the reflash is: Are they reusing the old fluid or just refilling with new, And how many of you are paying for it?

Seems if its a recall, they would just handle it. Am I wrong?

Three Way in Bakersfield did my flash, said nothing about any DEF (but it was close to full) and the charge was $0

Got my recall last night (Canada). It says that the recall is voluntary. Goes on to state "the Diesel Exhause Fluid (EDF) injection system may not operate as intended. If this occurs the Malfuncion Indicator Lamp may illuminate, a DEF system warning may be displayed in the DIC, and vehicle speed could be limited. Under certain circumstances the vehicle's emissions could increase".
It also states that " you GM dealer will reprogram the engine control module and install a shield and insulation to the DEF tank". They say that we should have the software update done now and the shield and insulation later when they become available, some time in early fall.
I had my reflash done mid August before my trip to Florida towing approx 9K lb trailer. Average fuel mileage was 10.5 mpg towing there and back. I recently went on a 400 mile trip and averaged 21.9mpg (no load), mostly highway driving.

When my reset reflashes were done both dealers used new fluid. No charge.

I don't think they need to use fluid if it is for the recall.

Unless you need tags right away you could always delay until tag time -- incase there are updates to the recall. We know there have been many revisions to the reset update. (including one after the recall was released)

OK, Got the reflash. They charged me for the DEF to fill it up again? So far, have not noticed anything. Time will tell on the mileage.

Oh, And I have a leak. They say its the upper pan gasket.....Great..........

Did they do the recall flash or the level reset reflash?

Both I guess. I had the recall notice that they did and had to top off the fluid for the level to register. Who Knows. I am begining to think they do not even know........

Glamis, who is your servicing dealer?
Cormier, in Long Beach, (where I purchased) and 3Way in Bako, (where I have had all the service) have all been fantastic, even if you didn't buy there
