Cost for 2013 C350 Timing Chain Replacement
A rattle when I start the engine of my 2013 C350 has been diagnosed by the local dealership as a stretched timing chain (at 78,000 miles!). They say the timing chain adjusters, four camshaft adjusters, and timing chain need replacement. They quoted $9,800 for the job. Is this as unreasonable as it sounds like it is?

Xsever, thanks for the bulletin. Unfortunately, my engine number is 276 9xx 30 423764 - higher than the engine numbers listed for repair. It seems like M-B still has a problem, though. Heck, a timing belt can last longer than that!
I'll be checking with the local indies Monday.

Thanks, Alfadude. I missed that part. I should have known I could open a PTSS case and sent it to SE! I'm going to the dealership today and give it a try.
Adi-Benz, after this experience, this will likely be my last Mercedes.

One of the best lessons learned from research is to never buy a car the first year it's out and to never buy one with a first-year engine or transmission because that's when all the teething problems occur.

Well I went to the dealership and asked about a PTSS case. The Service Consultant said that process was to verify the diagnosis, not evaluate the possibility of covering the repair by Mercedes-Benz. He did give me a phone number for M-B Customer Care to make a claim that the repair should be covered, at least in part, by Mercedes-Benz. Surprisingly, after leaving my information, a nice young man named Lance called back, but was perplexed as to what I wanted Mercedes-Benz to do. I told him M-B covered the same repair needed on mine on the same engine, and that apparently whatever correction they made in subsequent engines didn't work. He said he would review my record with Mercedes-Benz; how many cars I've purchased from them and maintenance records for these vehicles. Silly me, I thought the decision would be made based on how much Mercedes-Benz backs up their vehicles, not on how much money I've spent at their dealerships over the years.
I also asked the Service Consultant how many hours M-B allotted to the repair. He said 18 hours, but that it usually takes about 20 hours. OK, 20 hours, they charge $189/hour so 20 hours X $189/hour = $3,780. He said the total cost is $9,800, so if I subtract the labor from the total, that leaves $6,020 for parts and shop rags? He had no explanation.
I went to a local German repair shop ("Factory Trained German Technicians") and they quoted about $2500 for the repair. I told him the dealership said the top of the engine had to be pulled to get the job done; he said they could probably do it with a chain link.

Curious about the last poster's phrase "... horror story chapter in the M276 book" ... I did a search and couldn't readily find any other dramatic M276 issues discussed here in the W204 forum.
The OP's issue is certainly a bad one, but what am I missing that qualifies the M276 as having 'horror stories'?

Xsever, I was told the chain was "stretched" but from what I've read and what you say, it is really a problem with the chain tensioners. My understanding is that the tensioners are hydraulic and leak down over time. That's why the problem only occurs with a cold start. Since my engine number is not covered by M-B for this repair, does that mean that it came with check valves already installed in the engine?

For anyone following this saga who has a M276, there is no good news for you. Mercedes-Benz did give me a "Goodwill Offer." They offered me 10% off the repair cost, $1000 off a new M-B, or $500 off a used M-B. If I had a record of giving more money to M-B (they couldn't count all the parts I ordered from them online over the years), I guess I would have gotten a better deal.
I got the service advisor to print out a breakdown of the repair:
Parts:
Four (4) camshafts: 2@$1,086, 1@$1,064, and 1@$1,103
24 hydraulic elements: $967
1 chain: $122
1 chain tensioner: $177
1 chain tensioning rail: $283
Miscellaneous: $60
Labor: $4,625
Tax: $360
Total: $10,976.10
The advisor said there are a lot of 350's with this problem. He tried to tell me that M-B improved engines by going from timing belts to timing chains. I asked him if chains were so much better, why is the chain worn out on an engine with 76,000 miles on it. He just shrugged.
They did a recall, removing the air bag and steering wheel to put a clip on a ground wire. They're worried about a ground wire falling off but seem unconcerned that timing chains are chewing up camshaft sprockets.

Wow, that is sobering. I wonder why they propose to change all four cams and all 24 hydraulic lifters, but only one tensioner and chain? Would damage on one bank of cylinders affect the cams on the other one?
Was the original symptom a rattle every time you started the engine? Or did it only occur with a cold engine, or after the car sat for several days without being driven?
An independent might be able to source a set of good used cams (like https://www.ebay.com/sch/i.html?_fro...+M276&_sacat=0) and a set of aftermarket lifters, since that's where most of the parts money is. Obviously the labor is going to be a lot no matter where it's done :-(

Here's what the mechanic wrote up:
"Intake camshaft adjuster bad verified customer concern, performed QT fault code PO34600 position of intake camshaft has a malfunction, recommend replacement of camshaft solenoids to rectify customer concern."
It appears they want to replace everything so they won't have to go in there again. Understandable, but at a high cost.

Anyway, I am sorry to hear this @Moxostoma . How much did you buy this car for and how much is it worth now if it were running in tip top shape?

Well an engine swap is probably way cheaper than this repair. Maybe you can cram a wrecked C63 engine in there for less money and have more fun.
I bet an engine swap is less hours and half the cost.
