And, as far as credibility goes, you are in absolutely no position to make any statements... the claims that you post on here are about as credible as receiving divine guidance from the talking octopus. Put that in your pipe and smoke it.
To say MB never was proved to cheat on emissions is not actually the truth, is it?

Point made. Who named the (so called) device?

Sprinter vans and passenger cars with undisclosed AECDs and defeat devices programmed into the vehicles’ complex emissions control software. These devices cause the vehicles to produce compliant results during emissions testing. But when not running a test, the vehicles’ emissions controls perform differently, and less effectively, resulting in an increase in NOx emissions above compliant levels.
Mercedes lies, only a fool still takes what they say at face value.

There is no one answer, it is all up to interpretation and how much you want o pay your lawyers.

Why continue to own a Mercedes if you believe Mercedes is a lying company selling crap vehicles? Sell that Mercedes, buy a Ford, and get on with your life. Or is arguing on the internet your hobby? Yeah, that's what it's really about.

I swore MB off and switched to Volvo for me and my wife for years. She needed a car and drove a 2014 GL450 and loved it. Car seemed strong and decently built so we bought it. We ditched it in ~45,000 miles due to cylinder scoring, prior to 100K miles. In talking with a factory service tech rep (not a dealership mech) there are tons of M278 engines crapping out all over. I will say I am having good success with my 2013 GL350 but it stays on the highway, 70% highway at a minimum and I service the hell out of it. Some say I’m way past **** on my service regime. And no, I do not use 229.52 oil.




1-123 240D (started my appreciation of their engineering)
2-123 300D wagons; well over 300k miles each
1-123 300D sedan; into the 400k miles
1-124 (1995 diesel sedan); almost 500k miles
1-1999 CLK-320; 130k(ish)
1- 1989 260E; around 200k miles
1-2014 GL450 w/m278 engine 96k miles (see pic below)
I currently have
1-123 wagon; 225k miles
1-124 (1995 diesel sedan) 130k miles
1-x166 (diesel) 226k miles
Now
I do almost 100% of my maintenance now and did do 100% of any work on them when I was in my 20-30’s. I have personally watched, in general, their decline in quality over 34 years. The exact statement from a regional service tech from MB in Jacksonville, FL was “yeah you were correct about the m278, they are not aging very well”.
Also, my current mechanic is a past 35 year master tech (45+ years now specializing in European cars) with the local dealership who went out on his own (have known him since I got my first MB, the 240D) and he agrees with few exceptions. I took my 2013 GL350 to another Euro shop here in town because my normal mechanic was backed up 6-7 weeks and he wouldn’t even touch it stating that the x164 & x166 models were such POS’s that he wouldn’t work on them, especially the diesels.
BS, not so much; critical opinion absolutely.

**UPDATE**
Around 245,000 miles now; no changes, lol (oh yeah 1 change, AC compressor replaced) I have run 2 rounds of Valvoline Premium Blue Restore through the engine 3 oil changes apart. It was not using but about 3-4 "ringlets" of oil before the PBR and is still using 3-4 afterwards. Using the PBR just gives me peace of mind that the engine is as clean as I can get it for max longevity. Last oil change of PBR I sent off a sample to SPEEDiagnostix, no issues that I can tell, tell me if you see anything concerning.
