When heater quits do they put new tank with heater installed due to to possibly contamination? Or use old tank?
I couldíve swore I read they were putting new tanks in as 1 unit due to too many 9th inj going out after heater only install.
Tech didnít want to hear that n said they drain tank and put fresh in .BS cause they didnít drain it.So any dirt from removing heater could contaminate fluid.
Went bad at like 58k

My DEF tank pump was replaced two weeks ago under warranty with about 66k miles on the clock. No warning no nothing the dash just lit up "Service Emissions System" with a mile count down to get it done or speed limited to 65 mph.

I am currently working with a shop to delete the trucks DEF, DPF and turn off EGR with a stock tune. No high performance for me just need the troublesome emissions stuff out of my life for good. Only problem I have had from the truck so far is emissions. Ordered a pipe a week ago and have not heard back from them. However they told me up front due to recent epa crackdowns it may take a little longer than usual to get the pipe.

I have had the heater replaced twice. The first time they replaced the tank and heater. I believe but not certain that GM didn't have the heater as a separate part. Possibly GM at the time covered the whole cost and the second time possibly GM for reimbursement to the dealer GM stipulated to replace only the heater unit. Anyhow both times it was GM extended warranty coverage.

Recently, about 2 weeks ago the DIC message, poor DEF quality flashed up. I thought oh no what now. The tank wasn't empty. I filled it up, maybe less than a quart I had to add. After driving a while the DIC message went away. Sounds like that is a PITA to determine the cause if the message stays. Could be any number of reasons so it has to be diagnosed.

Funny thing even the service writer hinted at getting rid of that crap. He would have given me a name of a place to do it if I wanted it done. He said many customers have done a delete. They just didn't want to have to deal with DEF issues again. I don't remember if he said they leave all that on and disable it or remove it all. I said yeah about the time I do that they will pass a law that you can't trade it in deleted.

Just had my heater replaced in my '13. I had an issue with a high idle that turned out to be the injector for the regeneration so both things were covered under the 10yr 120k extended warranty on the emissions equipment. I never get that lucky.... It was short lived, 3 days later I have a kidney stone. That's more like my luck.

I had a 11mm kidney stone. The ER doctor said I don't think you will be passing that one. I was like give me about 50 syringes of that pain killer to take home. I had lithotripsy done to break it up. Felt like pi$$ing sand after that.

About a year later I had a urinary track infection that went septic. Found out I had prostate stones along with an enlarged prostate. Lucky me I came with a 3 lobe prostate, normal is 2. I am more sexy I told a friend. Enlarged prostate I take flowmax and finesteride and now I have gone from a size B cup tits to a D. Been thinking about doing a spread for Playgirl. LOL

I’ve got a 2016 Duramax lml With 66,000 miles. I’ve got a p140b code and a p049d code showing at the same time. Clear it it doesn’t show back up on the same drive until I turn it off then back on again. But occasionally it’ll throw a nox code. It does sound like I got a bit of a tick sound. Especially when I’m at a dead stop and Accelerate, sounds nearly like it’s about to cut off sometimes. Went into regen, everything ran fine, and when I stopped at the house put my truck in park the truck started to surge pretty badly. Jumping from 640 rpm to close to 800 repetitively.I’m getting a delete tune, and egr delete and def delete Tuesday. I’m just hoping that’ll fix my issue
