That didn’t last long

CEL back on

This is baffling. The last guy clearly did a guided fault finding but was wrong. They still haven’t replaced the DPF itself - wondering if it’s clogged.

 

[pjlipeika]

just to update, received a call from the dealership...
they are replacing the upstream NOx sensors now. In addition the DPF is bad, and will be around $2,500. He is going to have his warranty manager look into it, but does not believe it is covered under the emission warranty, and will be an out of pocket expense for me.
Does that sound right? Is a DFP not covered under this warranty?

 

[Hirnbeiss]

The way I read the warranty, p34, is that the filter specifically IS covered.

Update:
After another week in the shop, she’s back.
Per notes from paperwork:
“Check engine light is on for non-efficient diesel particulate filter. Performed systems quick test and found fault #P200200 The efficiency of the diesel particulate filter (cylinder bank 1) is not sufficient. Followed test steps to replacing DPF Catalyst with new. Removed and replaced DPF catalyst assembly with new, cleared faults, perform teach-in for component DPF reset adaption, and reset ok.”

Third time a charm? Fingers crossed!

Quite a good progress I do hope it gets fixed though.

Most of my drives are typically 1 hour, 20 mins. It is my commute to work 2-3 days a week. Other than that, I have an occasional "around town" drive, but not often.

I do all my oil changes myself, with the kits of Liquid Moly from FCPEuro, specific for my diesel. I have always been about the "preventative maintenance" measures. Take care of it now, she [the Benz] will take care of me later.

Also, to provide an update, I dropped her off at the shop today. Fingers crossed this all works out and will be covered under the warranty. I cannot thank HIRNBEISS enough for pointing out that footnote on the coverage details.

I know this is an old post, but how funny MB doesn't bring up their 8/80 exhaust warranty until you either read it or someone tells you about it. There is such a thing as a "Limited Warranty". They don't have any documentation on Limited. So vague that what they express as a Warranty, it should be covered. I'm fighting that battle currently. Very big stain on the MB brand right here. No one at MB did their home work. Their legal department dropped the ball on this.

I’m glad you got Ciesel back up and running under warranty! What dealer did you go to? I live in the Berkshires and looks like I have the same issue at 63k. My CEL came on, went to Napa to use a scanner: P2002 permanent and P0116 Pending. I cleared both of them just to double check they’re valid. CEL cleared and didn’t come back on for the rest of the day running 2 more errands. I figured perhaps the long drive I took before I read the codes cleared out the DPF and the CEL just didn’t reset itself. Then I went to drive today and no CEL but the temperature gauge for the engine was not working!! So I stopped at Napa to use the scanner again even though the CEL was not on. Same codes were there. I started up the car again to head home very carefully, but the temp gage was working, yay!

Any how, since the scanner read a P2002 I figure I should get it checked at the dealer since it’s still under warranty, right? So I wanted to go to the dealer you went to since it was successfully taken care of under warranty.

Thanks in advance!

Why do folks put up with modern day unreliable diesel systems anyway? Cause diesels are just cool? Unless you are towing 25-30k lbs they are totally useless!

Snakes are cool too..but I don’t wanna own one.

Diesel gets enough better fuel mileage that even with a higher cost per gallon it is cheaper per mile and it really shine under high load conditions.

It just doesn’t feel like that’s true. Xtra cost per gallon, extra cost of vehicle at purchase, extra cost to keep it repaired, worry that the dep system is gonna brick you any min, etc. Extra load? On a GLK? You ain’t pulling a 35’ horse trailer with that GLK. Gas burner GLK is a much better overall vehicle.

That is funny even though I realize it's directed against me. Hey, yall enjoy stinkin and clangin around in those oil burners. Whatever ya need to do to feel like a man. Mo powwa to ya..

I guess you don't have much experience with them...

The Diesel cycle is more efficient, so we're helping save the planet by producing less CO2 per horsepower.

I have owned 2 different old Powerstroke Diesels (a 2000 E350 van and a 2003 F250) and yes I get it, they were insanely powerful and very efficient for their size etc. I towed my 69 Bronco all over the country to off-road parks back then. Fast forward to Today and Today's ridiculously choked down and Extremely Overcomplicated Diesel powertrains and it's a hard pass for me. I will just have to save the planet in other ways besides sitting on the side of the road on account of my modern diesel has decided to shut itself down again for the 6th time this year.

But hey, I recycle, I take my used oil to Wal-mart, and just the other day if flipped a turtle back over off its back, so I'm doin my part..

 

[John350]

flipped a turtle back over off its back

All is forgiven!

I had an '06 Duramax. Granted, it was pre-DEF, but it definitely got the job done. Zero breakdowns. The GLK is a sweet ride. So far, so good... If it goes past the extended warranty and starts giving me trouble, and I can still get away with it without being canceled, I'll "delete" it... Still cleaner than a coal fired charging station.

[Edit]Prior to the D-Max there was the '87 F350 7.3, '93 C2500 6.5, '95 K2500 6.5. Then there were the, '90 MB 350SDL, Kubota 7510, and 65 hp Zetor. During my college days I had a 190D beater.

I’m driving two MB’s right now: a 2015 GLK 350 2WD, and a 2020 E200 (yes, not available in the US anymore). The gas GLK gets 10L/100km*, while the E gets 5. That’s right, the lil ol’ diesel gets twice the mileage of its Otto-engined cousin. This is why people drive diesels.

It is also no slouch on the Autobahn.
