Cowpie Posted December 1, 2018 Share Posted December 1, 2018 (edited) Just came across an article that was published in the last couple of days where the EPA is now cracking down on those who are deleting emissions on diesels. $4600 fine per occurrence. $46,000 per occurrence by a shop. The parent company of Bully Dog got whacked for 6.5 million dollar fine. Might be just the EPA making an example of some to make others color within the lines, but one has to ask if they want to put their back end out there for the EPA to whack it. I understand why one would want to. I am for eliminating the stuff. But keep in mind, the EPA is looking to increase their bank account and they have turned their eye to these things long enough. it would not surprise me if they strong arm shops into reporting of vehicles where the emissions stuff has been monkeyed with. A real can of worms if there ever was one. It would seem the best method to address the problem, with the least exposure to a problem, is eliminating the operation of some of this stuff via ECM software programming. Still a risk, but if all the stuff is still on the vehicle, it is not as easy of a target. Edited December 1, 2018 by Cowpie Quote Link to comment Share on other sites More sharing options...
Mikey52 Posted December 3, 2018 Share Posted December 3, 2018 Or have congress rein them in some. After warranty has expired, should be mine to do with as I please. Coal rollers didn't help. Quote Link to comment Share on other sites More sharing options...
Barbara Martinez Posted August 6, 2019 Share Posted August 6, 2019 My 2012 Chevrolet Diesel Silverado Truck 136,000 miles engine light and warning light for exhaust fluid issue. Dealer says tank and heater part cost $300. Total cost for job could run $1000. Waiting for truck now. Put in shop yesterday and won’t be ready until tomorrow. Says guarantee for 2 years. Had def injector replaced in October of last year and that costs $600. Def sucks and should have recalls Quote Link to comment Share on other sites More sharing options...

Tita Posted September 19, 2019 Share Posted September 19, 2019 My truck is 2016 gmc 3500 serria denali. Any advice? I could really use some about the def redundant tank heater issues Quote Link to comment Share on other sites More sharing options...
ralanis6 Posted February 9, 2020 Share Posted February 9, 2020 I have a 2016 Chevy 2500HD and had this issue at 43,000 miles. Dealer replaced it and I am glad it was covered by warranty. Have not driven it much since then. Quote Link to comment Share on other sites More sharing options...
Phyxius Posted February 21, 2020 Share Posted February 21, 2020 I have a 2016 3500 and had the check engine light come on last week. In the dealer right now posting this, as they're replacing the DEF heater. 44,433 miles Quote Link to comment Share on other sites More sharing options...
Colossus Posted February 22, 2020 Share Posted February 22, 2020 Not surprised. DEF heater has been a pretty common failure on the LMLs. Had mine replaced twice on my 2012. Quote Link to comment Share on other sites More sharing options...
Jminter6001 Posted March 28, 2020 Share Posted March 28, 2020 Also have the 2015 LML. I see where a lot of peoples trucks went into Limp mode once they got the P21DD code. I never did. Drove it 1,000 miles and no limp mode. But I changed the DEF heater myself and the code is still there. So what could the problem be if it's not the DEF heater? I know if I take it to the dealer they will try and get me to pay for another DEF heater. So I'm trying to avoid that. Any ideas? Quote Link to comment Share on other sites More sharing options...
GMCHD2015 Posted October 18, 2021 Share Posted October 18, 2021 Had my Def Tank Heater replaced last year under warranty. They gave me a 100000 mile extended on it. Def is highly corrosive. They have to remove the tank and install waited 2hrs. Quote Link to comment Share on other sites More sharing options...
JLP01 Posted March 16, 2022 Share Posted March 16, 2022 I have a 2021 duramax 3500 with 11,000 miles. Having the same problem. Dealership called and can't get parts, so they are hoping to have it fixed some time in June. My truck is a sitting duck and I have to still make a payment on something I can't drive. I had to purchase another vehicle just to go to work. This is beyond frustrating to say the least... I just want to sell it! Quote Link to comment Share on other sites More sharing options...
