2012 C250 Cam Shaft Adjuster issues

Engine light came on, intermittently. Took it for oil change that was done by independent MB Certified Mechanic. Independent mechanic told me to take to dealer to get diagnostic done. Engine light didn't come on a few times before going to dealer (where i originally bought the car and have had all services done). I was told by dealer that the engine light was turning on because I was having issues with cam shaft adjuster. I asked for the diagnostic code, but the Customer Service Person would not give it to me. I have 57K miles on the car, out of warranty, and have been quoted $4200 as an estimate to have everything fix (which will take 2-3 days to fix). From my review from previous posts and NHTSA, this cam shaft adjuster seems to be a problem. Not sure if it was the same issue with other MB Owners from the class action suit MB settled in Majeed Seifi et al. v. Mercedes Benz USA LLC, case number 3:12-cv-05493, in the U.S. District Court for the Northern District of California. Need guidance. I am frustrated with a large expense for car at less than 60K miles and not even 5 years old. Losing confidence in the MB Brand and Service. Any advice would be appreciated.

Miguel, sorry bud. I really don't have any great advice, just my sympathy. I'm in the same boat as you. My car is actually in the shop as we speak. I might get it back tomorrow. My 2013 C250 started with a "diesel car starting up" noise like this...
https://m.youtube.com/watch?v=HhLEQ5914N4
I had no engine lights nor was the car performing any different. So I said to myself, let's just take the ol' boy in...to be preventive, but after my local shop went in for a better look I got the devastating news. It was indeed the cam shaft adjusters (there's two by the way an intake and exhaust) long story short I'm bracing myself for a nice chunky bill in the neighborhood of around $3.5k. The worst part about it is I could have done the work myself, but work and life in general, just won't allow for that kind of time. So frustrating!!
If it helps any, I've come to the conclusion that if we want to own pretty things, we'll have to spend a pretty penny now and then... but I'm definitely looking into an extended warranty provider. I would suggest the same to you. Good luck man!!

Dragger,
Thanks for the sympathy. So are you still under warranty? I am not and the dealership that I bought it from just north of Winter Park, FL. Offered and rescinded good will twice. I am having to get MB, USA involved, but they are not calling me back. Dealer doesn't want to even touch my car anymore, they told me to take it to South Orlando and North Orlando to have the work done. I am still frustrated. Ed Taylor, Service Manager won't even talk to me nor the Business Manager, Maia Melendez. My last communication from them was just an e-mail rescinding the service goodwill and doing further services. Dragger, Be cautious. I understand you get what you pay for, and spending money for pretty things need to be done, but in the first 60K miles I shouldn't have this issue. Think about what you are going to do. The Blue Book Value on these cars is about $20K. You are about to spend 20% on the value of the car for upkeep and maintenance. It surely will not increase the value. MB knows this and that's why they want to have me spend money on it. In my opinion, MB dealer and MB USA by their actions, said go it alone and are asking me the consumer to forward their brand and quality marks, by paying all for it on my own. I get the Luxury Brand moniker associated with MB, but at the end of the day MB Dealer and MB Manufr is a business like any other (motivated by profit and dividends to investors). Words like "brand loyalty" and "the best or nothing" apply only to the consumer and their affection for their product, but not the other way around. I don't know about you, but I earn every dollar that I make (and I like what I do to have to make that dollar), I enjoy spending it, but for MB Dealer and MB USA to have the audacity to not address my concerns with their product is foretelling of the dealership's corporate culture and the manufacturer's corporate culture to ignore consumers and not care. In this age of e-mailing, texting, social media, it would be easy for them to reach out and just listen, but they won't even do that. I guess my frustration is leading into disappointment. May be I expected too much. At this point, it's not about being right, it's about being listened too as a customer. Looking back, I didn't even get that from MB Dealer and MB USA. Thus, it's led me to re-evaluate my ownership.

Miguel,
I do not one bit disagree with anything you just said man. Much like you I too work hard for my monies. This unfortunate circumstance also gets me to think twice about being loyal to any brand or company to be honest. Wouldn't it be nice if these big name brands really did appreciate our devition and enthusiasm we have for them by reaching out to you and saying... "Miguel!!, we're sorry this flaw in our engineering is causing you so much grief, let's take it in and get this thing purring like a Kätzchen" haha... I wish that for you.
I'm a do-it-yourself-er kinda guy, so most my frustrations is the fact I'm losing out on all that dough do to sheer convenience. I'm being told by my shop that this is somewhat of a common issue with this engine and that it's typical of failure around 60k - 90k mile... How true or accurate this really is, I suppose I will have to do some sleuthing. I don't want to have to do this repair again in a few years.
To answer your question earlier, no, I am NOT under warranty unfortunately. Had I had the slightest hint of the vaguest whiff that this costly repair was going to be had before hitting 100k miles I would have extended my warranty. Lesson learned I suppose.
I support you in your quest for customer service, acknowledgment, and resolution. I hope MB can maybe by some miracle assist two hard working car enthusiasts like us.
Let me know what the outcome is. Good luck man!!

Update. Took 2012 C250 to independent mechanic to inspect the diagnostic code P0340. Found that the cam sensor was fine and all the electric to and from the car computer was fine. After an hour of diagnosis, confirmed that the check engine light was coming on at the start (intermittently). Mechanic wanted to open up the engine to inspect the timing chain to see what's causing this issue. Cost $500 to open up and inspect. Mechanic said that this is just the start. He will have the keep the car for a couple of days. Thinking about what to do and researching whether it is true or not that this issue leads to catastrophic failure for the car (timing chain breakage). I am complete bewilderment as to how this could happen on an engine with less than 60K miles. Again, evaluating my options. With the amount of time I have spent on this issue, MB should be paying me for loss time from work.

57k miles
Cam Positioning Sensor replaced 2 days ago and the CEL is back on.

The indie mechanic I took it to thinks it's the timing chain.

Were you able to resolve with MB dealer? Did they offer any goodwill discount for the service?

I was barely out of warranty and these problems came up.
I'm in West Palm and terrified to drive the car out of my neighborhood, much less get on the highway.

Hey NZounis,
No. I wasn't able to resolve with MB Dealer. They left me hanging out to dry. I had to call Mercedes-Benz USA and get them involved. But they kept delaying the investigation. After a week, I got a phone call back saying they would re-offer (a 2nd time the goodwill) but I had to go to another MB Dealership on the North side of Orlando to take a look at it. I was willing, until I found out that the Orlando Dealership and the North Orlando Dealership are owned by the same company, AutoNation. So two weeks without car, and very poor customer service with Dealership, and not enough support from MB USA, I made a decision to get out of the brand. What really frustrated me is that during this entire time with my car, MB Dealership Sales was calling me to get into a new CLA for the same payment. It really burned me to think that their slogan "The Best or Nothing" does not apply to them, it only applies to you when you buy their product, and that they wouldn't back the product and try to sell me a new car. As for the Goodwill discount for service, no. Dealer stated that the service was $4,200, and that the Goodwill would only go to the parts, $2400 and I would have to pay for the labor, $1,800. I was able to get them to $1,200 in labor. I asked for full written estimate of parts and found that they quoted them on my estimate at above retail. I was disappointed. Good Luck. I hope your experience is better than mine.

C250 2012
I just got replaced the 'bank 2 exhaust cam solenoid' on my C250 2012. I am in Canada and have MB Star certified warranty which covers the engine..or better said 'some' parts of it!
Can anyone tell me if this solenoid is part of the engine or not, so is it or is it not covered by warranty?

Thx in advance

2013 C250 cam adjusters

Just wanted to add that in March 2018, MB USA authorized replacing my faulty cam adjusters under warraty even though warranty expired 7 months ago. Mileage was right at 50k. Dealership said it was a known faulty part but not enough of one to initiate a recall. Originally quoted $4,500 for the work, but service rep. said that after talking to "Mr. Mercedes" they would do it under warranty. Was very relieved and would encourage anyone with the clatter at start up to push the matter through your dealership. I live in Northern California where the dealerships have apparently NOW got the message.

I live in Montana, I am going to go ask our dealership about this today; I have 54k on the car and am the 3rd owner, getting the rattle on startup and after doing research I know full well what it is. <br /><br />I'm expecting a "no" from them regarding helping me, and I was wondering if you would possibly have the time to put me in touch with someone who helped you and see if they could pull some strings for me? I would appreciate it so much, as I'm trading the car off if it isn't remedied...thank you SO much in advance for anything you may be able to do! <br /><br />QUOTE=Benzo2013;7431420]Just wanted to add that in March 2018, MB USA authorized replacing my faulty cam adjusters under warraty even though warranty expired 7 months ago.

Zachgoggins, sorry for delayed response. The dealership in CA that worked with MB USA to get my 2013 cam adjusters replaced under warranty was in El Dorado Hills. 916 567 5100. Service Manager's name was Daniel Clark. We were original owners and had the dealership do all maintenance throughout warranty period, car just at 50k, but over months on warranty. Not sure if any of that helped. Best of luck with your car.

2012 C250 Coupe
I'm another victim of the "Death Rattle" on starting, then runs perfect. Has anyone tried an oil accumulater? after market used by racers, classic cars, @ $300-400 plus install, you activate before starting, it pre-pressurizes engine, would lock sprockets. MB service rep told me the sprocket seals stop holding oil pressure, $3,400.00 to replace.

Warranty ! What difference does that make ? Mine was under warranty 48000 mike and MB told me that because I didnt use there oil filter I had voided my warranty and the repairs would cost me $4200 ! Then asked if I wanted to pay cash or credit card ! I got the same response from everybody I tried to reach out to at MB. A deaf ear no return calls or emails . I have owned there cars all my life . Im almost 50 and this is my 7th car I have bought from them all of them brand new . I felt like like I had been slapped in the face . I have spent well over $250000 with them if you ad them all up. Sad thing is they really dont care . So I sold my suv I had bought from them last year , took a big hit on it . I didnt care I m done with MB . Ill never own or drive another one again . I would rather drive a Yugo ! I feel ya guys and everyone else out there thats been screwed by MB. Only thing I know to do is never own or drive another one of there piece of crap cars again . Wish I would have know how valuable I am as a customer to them a long time ago !
