New Year....Same PROBLEMS! (GM Duramax LIMP HOME 4mph - DEF Fluid Quality Poor?) 

Same here. Lol.

I always run RU-vid videos with CC’s. Unfortunately, it wasn’t included with this video. Legibility and volume major issues on RU-vid.

Gasoline engines too.

the overall plan is to get diesels off the road anyway, so to achieve this they are just making them more and more complicated. "Electric is the way to go", whether it works or not.

All that trouble is why there's a market for "workaround" boxes.

It just isn't the newer ones, either. I recently had an issue with my 2005 F-350. One day the truck wouldn't even "click." I posted online and a gentleman told me the fan clutch circuit under the hood was damaged and the body control module was holding out the starter circuit. Well, what kind of crazy crap is this.....I pulled the fan shroud off, the plastic conduit carrying the wires to the clutch had failed, dropped into the fan and got chopped up. Well, there's your problem, lady! You also need a special tool to remove that fan clutch. I have had EVERY problem you can have with a truck.

The phrase that will shake out is going to be "carbon neutral" in the end. The ICE is not going anywhere. Electric cannot sustain the rigors being asked of it. The average driver segment electric may be just fine but the sport job/work segment needs the ICE for as long as there is fuel. Strides are being made to utilize carbon captured from the air to make gasoline. Putting the cart before the horse by satiating the production greenies and not having solved the charging availability is making for less than stellar reasons to want to go electric. Social media is proving to be its own worst enemy.

Seen that on many vehicles.

Me too.....!

Yep, it probably won't run a regen with that glow plug fault. It's only a matter of time before the "new" DPF is clogged.

Trouble with big diesels is they can take twenty minutes driving to get to “normal temperature,” with 75 minutes regen on top of it, driver is not going far that day, wait ! can you take static regen out of a commercial driving day ?

I knew that. I also know when these systems came out (I think it was 2008, at least on Ford) the vehicle could go to regeneration while idling. I think there was a reflash done so the vehicle had to be moving at least 20 mph before regeneration occurred.

That’s why i still daily drive my ‘07 duramax, no def or regen crap, never seen a check engine light other than for glow plugs.

@@ronfrance4041 The older diesel vehicles must have a much higher resale value because of over-regulation

@@kerrylewis2581 yup, they do now.

I got rid of my Ram with the Cummins for the same reasons. I also now have an F350 with the 7.3 Godzilla gas engine and have been very happy with it!

@Kerry Lewis, I've never owned a diesel but the majority of my negative experiences with gasoline vehicles has been the emissions systems. A family member launched the "parts cannon" at one of his vehicles trying to fix the repeat codes. On another vehicle which was nearly 20 yrs old, I had to replace a long section of pipe with the integrated CAT and an O2 sensor "fused" to the pipe yet the replacement had the wrong angle at the socket & flange. I had to cut it and use the factory socket & flange so it'd finally line up and seal properly... 😑 On another vehicle it seems like every other week to a month I would get, "check gas cap, small leak, large leak, catalyst inefficiency, incorrect purge..." etc., yet after resetting the MIL a few times, suddenly no issues or codes have set for months & vehicle passed emissions testing with no problems. 🤔 It's absolute nonsense just how much of a headache and how much wasted $$$ has gone into repairing "emissions components" on modern vehicles compared to other components. And yet now they want to "GET RID OF ALL GAS/DIESEL ENGINE VEHICLES & GO ALL-ELECTRIC!!!" whilst all-electrics are still largely charging from sources utilizing fossil fuels which then is contrary to the very reason that the vehicles exist and then they have their own set of other problems.

I sold my emissions equipped trucks for older pre-emissions trucks. I have never looked back.

Great info!

Does it run the glow plugs in regen?

@@kevin9c1 yessir, they're also programmed to abort regens for all kinds of other reasons. Always a good idea to baseline everything engine related and make sure it's working properly in a situation like this to make sure the repair lasts and that the original cause of the fault was actually the part that got replaced.

Tech 2 worked on 2015? I thought 2013 was last year of Tech2?

@Pine Hollow Auto Diagnostics that's what i thought too. But it did work. As the setup is pretty much same. Only difference is the engine code. Like LML, LMM and L5P. But tech2 is dumb as it wont see that.

I'd like to upgrade to a Thinktool Pros, have you run into any compatibility issues?

@@mrfishbulb7187 I have been using it for more than a year now, I haven't encountered any issues yet. I even used it on a Mercedes and a range rover. It works great !

@@orkidorkid Ok great, thanks.

:)

A Duramax that is treated well and serviced is good for at least 250k miles. Perhaps injectors at some point but should go to 500k miles if well used.

Duramax is an Isuzu design.

Mine has all these functions as well, just have to make sure you are running 20.2 or newer

Yup needs glow plug #7 replaced 👍

@@PineHollowAutoDiagnostics What's your thoughts on the glow plug fault being the possible cause of the clogged catalyst? i.e not being allowed to regen because of engine light. Seems plausible to me.

​@@PineHollowAutoDiagnosticshi I have a gmc 6.6 20:52 2013 poor fluid quality on dash iam havein trouble doing the 70 min test as it fails I've seen that the dpf temperature is not getting hot fitted and tested 9 injector. Any help would be appreciated thanks

You need to dive into the diagnostics like Ivan has..otherwise sit back and enjoy the show. I am trying to pick up the lingo and methodology, its hard. He has learned the language of diagnostics...because he had to

not in the winter months!!!!!

Well when they are on backorder people find a way to get it done lol

@@PineHollowAutoDiagnostics Well, not in this case, but in some cases I have heard a term called "Russian Repairs."

Since the EPA wants people to only buy converters brand new and there is a backorder. people need to send the EPA rental car bills while waiting on "new" parts and see how quickly something would be done...

You probably don't want to eat what's inside of those machines 😂

I think the biggest problem with these new DPF system is training the following protocol if you follow protocol you'll fix the vehicle far as my opinion now they're junk

You can presure wash them :)

@@Adam-bw4lw Pressure wash the SCR internals?

He might have used the wrong oil in the engine(aditive package can stick to scr) in that case it might work

Hope youtube dosent hide my coment,similar situation ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ioClKA7DxYs.html

Just had a CAT excavator DPF cleaned $700 in Roanoke VA.

May cause higher emissions overall since that cylinder won't burn as clean if cold, but shouldn't cause the reduction test to fail since the computer is looking for a set %age reduction between the two sensors. I think?

@@MrAmorti The glow plugs only activate for the first 15 secs or so. Doesn't really affect anything other than cold starts.

@@MattyEngland I think you are talking about older cars. @neilmurphy845 may be right for some reason.

@@MattyEngland "Shouldn't" affect anything, but depending on the programming it may inhibit regeneration cycles

@@MattyEngland Glowplugs have to be working for an active re-gen cycle

Have one myself smog legal in CA federal emissions. I would love to get a newer. Can't pull the trigger

I definitely would not get rid of the non-emissions truck if you did buy something newer. I only have older trucks now and it's be great.

Not the Saab version 😉

Trouble is then you have a*holes rolling coal through the city, historic and other buildings turn black, kids get asthma, bla bla. The concept of diesel exhaust filtering is good, even if the execution needs work. Tbf though, this is a 10 years old salt belt truck.

Diesel engines should stay where they belong, in trucks and buses etc. Petrol/gasoline is a far superior fuel for smaller vehicles the size of a car

@@MattyEngland diesel has more energy than gasoline per unit. They work much better than gasoline engines when pulling heavy loads and have been more efficient in small vehicles. The emissions systems are killing them, dirty egr and massive aftertreat systems have reduced the reliability and efficiency.

@@bad05ford Only a tiny fraction of small vehicles are carrying heavy loads or towing. If every car on the road was a diesel with no emission systems, the air quality in our cities would be as bad as China. As for energy density it depends on the unit of measurement. Petrol has a higher energy density in term of MJ/kg, but diesel has more energy in terms of energy per litre. The majority of the mpg gains are actually due to the higher thermal efficiency of a diesel engine.

@mattbaber1980 dirty sooty egr is a problem aa well aa the low quality components in the aftertreat system. The technology has had plenty of time to mature like catalysts on gasoline engines.

Its the maintenance..gotta keep up with it. Look on the road..there are way more heavy duty diesel pick up trucks running on the road than in the shop at any time. My diesel is a Mack truck..2016..its gone 360,000 miles with no sensors problems, no def problems, never went limp mode. The technology works now.

If you do a lot of mileage then go diesel, if you do short trips and stop starts you'll eventually have dpf clogging issues etc.
