ecm reflash?
It's funny everyone talks about an ecm reflash to delete this and the dpf filter. I work at a dealership and CAN and WILL find the reflash very easy. When i do your warranty is voided for the failure you have. I can tell you that a dpf filter is $1200 plus install and takes about 2 weeks to get. there are safe codes built into the ecm that get changed EVERYTIME the ecm has an alteration, wether from dealer or aftermarket. if those codes dont match what gm says they should be, then you are on your own.
Also, as far as selling urea at the pumps, i don't think this is going to happen. as of now only at dealer. i think it is going to stay this way...

You really think if they are going to require this on pick up trucks they won't have the same requirement in Semis, BullDozers.. etc.. etc??
I doubt they'll be pulling into Ford dealerships around the country to refill their Urea tanks.

answers for urea
When contaminated or diluted DEF is suspected, the ECM initiates the DEF Quality warning process. Once initiated, DEF quality warnings grow increasingly more serious as the vehicle continues to be driven. The vehicle’s current DEF quality warning status is displayed on the scan tool. When a drop in SCR efficiency is detected, the normally OFF Reductant Field Quality Warning Indicator Command will display Warning Level 1 through Warning Level 5 depending on the number of miles driven, the number of ignition cycles, and if a refueling event was detected. The series of DEF Quality Warnings alert the driver that DEF system service is urgently needed.
lvl 5 means Warning Level 5 is triggered when the distance traveled is greater than 1000 miles and ECM detects a fuel fill event. The driver will hear 4 chimes on entering Warning Level 4. The series of 4 chimes will repeat every 3 minutes. The DIC displays the messages, "Exhaust Fluid Quality Poor," "See Owner’s Manual Now," and "Speed Limited to 4 MPH."
The messages alternate every 5 seconds until acknowledged by the driver; however, the "Speed Limited to 4 MPH," remains displayed on the DIC. The DEF Indicator in the instrument panel flashes continuously.
Vehicle speed is limited to 4 MPH maximum.
As far as the urea, The engine control module (ECM) monitors the DEF level and consumption rate in order to calculate an estimated range in miles remaining until the DEF reservoir is empty. DEF levels are detected by the 3-position solid-state DEF Level sensor. Typically, DEF warnings begin once the estimated mileage falls below 1000 miles. Once initiated, DEF warnings grow increasingly more serious as the remaining mileage decreases without a DEF refill. The vehicle’s current DEF warning level is displayed on the scan tool as Reductant Level Warning Indicator Command Level 1 through Level 9.
lvl 9 means, Warning Level 9 is triggered on the next ignition cycle following a second refueling event without a refill of the DEF reservoir. The driver will hear 4 chimes on entering Warning Level 9. The 4 chimes will repeat every 3 minutes until the DEF reservoir is refilled. The messages "Exhaust Fluid Empty Refill Now," and "Speed Limited to 4 MPH Max," are alternately displayed every 5 seconds on the DIC. Both messages remain on the DIC until acknowledged by the driver; however, the "Speed Limited to 4 MPH Max," message remains locked on the DIC.
The DEF Indicator in the instrument panel flashes continuously. The vehicle remains in Warning Level 9 until the DEF reservoir is refilled.

Urea tanks will be standard equipment for most new diesel trucks, buses, cars, and sport utility vehicles (SUVs) manufactured in the United States after Jan. 1, 2010. An automotive grade of urea will be injected into the vehicles' exhaust stream to "scrub" nitrogen oxide (NOx) from the diesel exhaust.
*snip*
Kedzie says that diesel-powered vehicles manufactured in the United States in 2010 can emit no more than 0.2 grams of NOx per brake horsepower hour—90% less than current emissions. The new EPA regulations will not apply to vehicles manufactured before 2010.
Tractors, bulldozers, and other non-road vehicles must meet the new EPA standards by 2015. The U.S. timetable for ships and locomotive engines has not yet been set.

tampering with the urea
The reductant system supplies the Selective Catalyst Reduction (SCR) stage of the vehicle’s exhaust aftertreatment system with the diesel exhaust fluid (DEF) required to reduce exhaust NOx levels. The engine control module (ECM) continuously monitors the performance of the reductant system during operation.
When the conditions associated with an attempt to disable reductant system operation are detected, the ECM activates the anti-tampering feature and presents the driver with a series of prompts and warnings.
Once initiated, anti-tampering warnings grow increasingly more serious as the vehicle continues to be driven. The vehicle’s current warning status is displayed on the scan tool. When tampering is suspected, the normally OFF Reductant System Malfunction Warning Indicator Command will display Warning Level 1 through Warning Level 5 depending on the number of miles driven, the number of ignition cycles, and if a refueling event was detected. The series anti-tampering warnings alert the driver that reductant system service is urgently needed.

This kinda kills the whole thought of buying the 2011 or any after that.It's funny everyone talks about an ecm reflash to delete this and the dpf filter. I work at a dealership and CAN and WILL find the reflash very easy. When i do your warranty is voided for the failure you have. I can tell you that a dpf filter is $1200 plus install and takes about 2 weeks to get. there are safe codes built into the ecm that get changed EVERYTIME the ecm has an alteration, wether from dealer or aftermarket. if those codes dont match what gm says they should be, then you are on your own.
With the way the dealer rapes you on simple parts, I can only imagine how much they will bend you over for a gallon of something that only they sell?
plus, when traveling, who in their right mind wants to be subjected to having to find a dealer every other day on their trip?
not going to happen.
Consider this, most people that buy these trucks are pulling trailers, not small ones either, you actually expect them to get off the highway, pull through some podunk town, the navigate the crowded parking lot of the dealer just to get 5 gallons of horse piss dumped in the tank?
On the bright side, my new 2011 full loaded GMC dually should be down to around 20 grand by the end of the first year.

I suspect some low sales on new trucks.i've heard that it is available online in 1 or 5 gallon jugs. as far as the price dropping because of this, NOT. lmao
My 06 should start going up in resale fairly soon.
generally speaking, very few people go to the stealership for anything after the warranty period is over.

by the way, I have to tell you that there are people out there that program in such a way that when you need to go to the stealership, you reflash back to original and it is never found.It's funny everyone talks about an ecm reflash to delete this and the dpf filter.

At least in my case it was never found. of course, I didnt add all the extra gauges either. matter of fact, the only gauge I plan to add is the pyrometer, and Im pretty sure the stealership would have found reason not to honor the warranty had I installed it before.

There's going to be a HUGE "greymarket" for pre 2011 diesels soon enough..
Can't wait for the "Government Recall (confiscation)" of all pre 2011 diesels "for the good of the environment", and of course "for the CHILDREN!!"

Actually, to be honest you didnt bring it to a dealership that has ran into the problem. like i said, if u program i can and will find it. everytime you make an alteration to the ecm you change the codes. no if's and's or but's. When you go "back to stock" program, you change the codes. i can see the last ten times the ecm was altered or datastream was opened. no way around it. it is a foolproof "clock" built into the ecm. So your flash back to stock. Lets say for instance, you were programmed with say EFI LIVE, and sometime down the road whilst still in the 5yr-100kmile warranty, you overboosted and did catastrauphic damage. first thing that happens is we have to start a case with gm. The very first thing gm wants is a picture of the scanner beside the vin showing the keys. the keys are then compared to the last 10 keys gm has given and if ANY do not match,(they are 15 digits long), you are done. the vin is recorded in gm database and no matter where you go your vin will be declined for all warranty work. last i checked a duramax comes complete at a cost of like $10g's and then the labor of like i think atleast 20+ hours.

Take a trip to your local farm store (Southern States) and you can buy urea by the 50 lb. bag. I don't see supply of urea and it's possible use as an explosive as a roadblock to a home refill kit.

Dude ..... anything Congress or the EPA mandates, because it is readily available and consumer ready, with x 4 the prices, and all available sources will be in the mid west 10,000 miles away from any refinery and have to be trucked in, increasing the cost again ..... *
