mb 2013 c250
The rattling noise can be a symptom of a failing timing chain. Without the check engine light and the P0340 code others (jcfergus) have been refused coverage.
If I can find the letter I will post it.
My dealer is about 50 miles from you — Mercedes Benz of The Woodlands on I-45 just north of College Park/Needham Rd.
FYI-An independent shop can do the repairs for about ½ of what MB will charge if you are denied coverage. But both the indie mechanics I know say that that after market parts are unreliable and recommend the Mercedes parts.
Also have your dealer check the in service date on your car. A 2012 originally bought in 2011 may be very close to out of the extended warranty. However, if it is a CPO from the dealer, it still has at least one year from the purchase date for all failures.

my grandmother recently passed away and left me her 2013 c250, the camshft problem presented itself almost exactly one month after the 10 year mark of the car, likely due to the low miles she had put on it the last few years. MB has offered no help but i noticed a CPO sticker in the door jam, this could possibly help me if that is the case that extemded warranty starts with the CPO purchase
thankyou !

hi - just reading your comment. when mb issues an extended warranty on an issue such as the 10 year cam shaft adjuster - is it 10 years from the first purchase of the car or 10 years from when one purchased the car as certified pre owned.

The extended warranty period starts when the car was first put into service. That’s usually the date of the first sale or lease. However, if the car spent any time as a program car, dealer demo, or loaner, then the extended warranty starts when it was first used for that purpose. Unfortunately that probably won’t help you with the repair cost. Most 2013 cars are beyond the extended warranty coverage. But a low mileage C250 is probably still well worth the cost of repair at an indie shop, but not a dealer. If there are multiple German car shops in your area, shop around.

In November 2020, Mercedes Benz began sending letters to owners of 2012-2014 C250 Sedans, 2012-2015 C250 Coupes, and 2012-2015 SLK250's notice of extended warranty coverage for the camshaft adjusters for a total of 10 years or 120,000 miles.
This coverage applies to all cars of these classes with the M271 engine regardless of ownership. If you have not yet had the work done, the coverage only applies to work done at a dealership. If you have already paid for the work done at a dealership, you should be reimbursed by showing a receipt. Work done at independent repair facilities may or may not be covered.
You must talk to a service manager. Service advisors or other persons may not have the information to properly handle your claim.
If you have not received this notice, contact the nearest Mercedes Benz dealer.
Mercedes Benz Customer Satisfaction is at 1-800-367-6372. They can direct you to a dealer and will put your name in a queue to be contacted by a service manager.
Good luck!

My Daughter's car, a 2012 C250, had one of the camshaft adjusters, timing chain tensioner, sliding rai , etc. repaired in 2017 by a Mercedes Dealer. Had code P034062. We paid $3,790.73,
Well it is now June 2025, and it apparently failed again.....$7,000 at dealer or $4,500 at reputable shop...
It was looking on Bring-a-Trailer for a replacement,MB and noticed several references to Camshaft adjusters in many listings. So, I thought there must be some action on this legally. I found your input here for Nov 2020. I found the 10 year extended warranty of Nov 2020, and on page two it says if repair has been done prior to that notice it can br refunded. Dealer says no as it is past the 10 years, but it was done 3 years before the notice, and we never received any notice from dealer who sold us the car originally.
HELP, I know it is 5 years but any insight would be appreciated.....Vaughn

I would call mb corporate and request a refund. Google it, it’s in Georgia. Get the receipts and diagnoses papers. I would think there isn’t any expiration, I received my reimbursement payment 4-5 years after the work was done at an indie shop.
As for the new issue, I haven’t had any luck with anything past their “extended warranty” (aka engineers screwed up but we don’t admit fault). I had issues with high pressure fuel pump a month outside of factory warranty. They would only offer me 2,000$ off a brand new car…. Lmao.
They sent me the 10 year extended warranty letter when my car was 11 years old. They wouldn’t honor that either so my car has been driven 120,000 miles on a defective high pressure fuel pump because screw them.

I was thinking that maybe you have some recourse in small claims court if they don’t offer you anything. But then there are statutes of limitations and it’s been a number of years. I ran this past a local former magistrate we know. Her response was, “How long ago?” She said she felt sorry for your loss, but would have to refuse to issue a subpoena to appear because in our state the statute would run out 2 years after the coverage expired.
