Major Failure at 30k

[Jefe1018]

I always chuckle at a statement like this. As though anyone is saying "it totally should happen!"

Of course it's not supposed to happen. That's why there's a warranty, and why you're getting it fixed for free.

I think it’s just frustration from OP honestly. Most people now a days have no technical knowledge of how anything in their life actually works, they want to hit a button, pull a lever, tap a screen and it magically works. With what we pay manufacturers, that’s the expectation. Reality and hindsight are 20/20. I’m okay with being this form of therapy for em, heck, he’s probably getting more engagement and give a flip from this group of enthusiasts than he’ll ever get from a service writer and big corporation.

I suppose my question is… will this be the last jeep he ever owns?

Just an editorial comment re: Euro powerplants under USA conditions. That diesel was never designed for the normal driving conditions we experience here. They have lower ambient temps, higher grade fuels, much less freeway-type driving, lower average speeds (simple factor of shorter average trips), etc. I worked for two Euro mfrs and watched one group of field engineers eyes open the first time they drove test vehicles NJ - Denver, the equivalent of London to Moscow, with a 5,000 ft elevation gain and midwest USA temps of 90+ fahrenheit. A 6 hour drive in Europe can cross several borders. Different world. They also can't grasp U.S. warranty laws, etc.

Despite the condescending tone here, you are asking the right questions, and I gave you possible causes and what to monitor.

To break it down further (based on the techs story):

-You either had a manufacturing error on your turbo; meaning tolerances were off and it eventually just destroyed it's own seals. Excess oil plugs the DPF.

-Driver enjoys the chug-chug sound and has caused excessive compressor surge (not saying you did but have seen it, usually from powerstroke guys) and caused seal failure. Excess oil to enter the exhaust plugging the DPF.

-Excessive soot generation from overfueling caused DPF plugging (internal engine diagnosed by pulling the downpipe). Turbo being under excess pressure and not rotating blew the seals. (The one I was concerned there's no notation of diagnoses).

You may have had a failed part and your good now (most likely), or everything that failed was replaced but root cause may still exist. If you don't want to pull your down pipe and check for excess soot your only measurement will be MPG.

This has been my profession for 20 years, parts fail, OEMs are getting lazier at quality control, but that's warranties exist.

I apologize if I sounded condescending. This is just very frustrating for me. I know gas engines very well, but I know nothing about diesel engines. I’m definitely becoming more educated since this happened. I was just looking for some input as to why, and your reply did answer most of my questions. Thank you. I’d like to find out what the root cause is because I’ll do everything possible to prevent this from happening again. I don’t understand what you mean by the “chug chug” sound.

Yes it is frustration. Yes it’s all repaired under warranty, but that’s beside the point. I’ve owned dozens of vehicles ver the years including Jeeps, and not one has ever had a failure like this at 30k miles. You’re right. I know nothing about diesel engines. This is my first one. I know gas engines very well. I’ve always done any work that needs to be done on my vehicles. You’re right, for what we pay for these Jeeps, you’d expect better quality and a bit more longevity.

Modern diesel engines are more complicated, especially with their emissions. With that said, there have been plenty of 3.6L Pentastar engine failures. I don't know if you pay attention to other auto remanufacturers, but Ford and GM have recently recalled tens of thousands of engines.

Sorry about your engine. Sadly, it’s about what I expect from an italian powerplant

The turbo is not designed or made in Italy. The turbo is made by Garret, an American company.

Not saying you are wrong, but seem counterintuitive to Euro conditions with lots of short tripping and extended service intervals would seem to build a more robust engine that would handle North American driving scenarios. I would think a company like VIM would understand and test for that.

I agree with this. I find it extremely hard to blame an engine design based on the continent it came from in this day and age of globalization.

I've rebuilt a few turbos when I worked for Elliott Turbo Mechine. Without having the turbo sitting in front of me. I can’t tell you the root cause. There can be several different causes. Warranty parts go back to the factory to be examined.

VM Motori put EcoDiesel test mules on boats and ran them in the ocean for hundreds of hours. So yes, lots of testing.

The turbo seal do go bad especially with the dealers using the wrong oil. There is a TSB not to use Rotella but the dealers use that since it's cheap. You have to let the engine cool also before you shut it down to cool the turbo center section. This is the case with all turbos. Let it idle or drive very easy the last 5 mins. If towing and going to exit and fill up, let it cool first 3 mins on idle.

The emissions systems have ruined diesel engines.

Do have a reference to the TSB that says don’t use Rotella? All I can find is that it depends on what Gen Ecodiesel it is.

I wouldn't go as far as to say that emissions systems have ruined diesels. I would say that emissions have complicated modern diesels and created a more costly ownership outside of warranty. We've seen a few bone stock EcoDiesels with over 300,000 miles. The highest mileage bone stock EcoDiesel that I know of has 474,070 miles. So, it's not all doom and gloom.

 

[Mike-len]

That’s the one I saw. Mine is a Gen 3. It doesn’t say anything about not using Rotella. You can buy Rotella 5W40 synthetic.

Sorry biodiesel. I replied to your thread about the guy saying there’s a TSB about not using Rotella….
