Out of warranty W212?
The dilemma is, a good CPO model is 4-6k more for 2010+ models, and given that CPO only gives extra year, basically I will be paying that much over for 12 month of warranty. The models I will be looking at will not be the p2 package, I dont need all the extra electronics, and normally will hold on to the car for few years. I know I can buy extra 2 years from MB, add another 2-3k for that too.
Does W212 uses standard OBD2 system, or it needs a specific MB diagnostic machines that only Dealers have?
Last time I worked with MB was years ago on 98 CLK230, lets just say it was not a well build vehicle, hoping the build quality of the cars was dramatically improved.
Anyone with expired warranty out there with some feedback on this?
Thanks.

I can scan my car with android and a bluetooth odb2 dongle, but it's very, very basic. You can reset a few codes, but not many. Also, that'll only do engine stuff. a Star SDS or Autologic does basically everything in the car (it's mind blowing to see the diagnostic tests available and the amount if information that can be read with the proprietary tools).
You can always look at spending a few grand on a chinese clone, but don't expect much in the way of support or updates.




With VIN, a dealer can check the service record if it's been taken to any MB dealer.
Also, an inspection by another mechanic may be a good idea. Not judging you at all, just think a second pair of eyes may be beneficial to you. MB dealer will check it over for $150-250. An independent may do it for free.
It's more about hooking up a proprietary "interface, reading the fault code then "R & R" (removed and replace) the faulty module. And the cost of the "modules" is the costly issue.
When I got our '11 E550 coupe last December, it had less than 17K miles on it and the warranty goes through November of this year. Even though I bought it from a broker, it qualified for the MB extended warranty which covers pretty much everything except wear items for a total of 7 years/75K miles with no deductible.
The cost was a bit more than a couple of the multitude of "modules" in our MB with P2 options.

Indi shop will do a PPI for around $50-$80 usually.




If you owned the car while it was under warranty and got a sense for how reliable that car was, then you'd have some background for that specific car. But if you are buying it out of warranty (like I did with mine) then you have to decide if you have enough information from its prior maintenance history.
I purchased mine through Carmax and got a warranty that will last me 5.5-6 years (based on how much I drive a year) for $3k. Warranty qualifies for a prorated refund before expiration. At that price point, I went for the piece of mind. If it had been more, I may not have. For example, dealer quoted me $6,600 for the Fidelity warranty which would have covered me for another 3/36.
First 2 were nearly bullet proof and I barely made back my "investment"
It turned out to be an investment in peace of mind.
On the 3rd car I decided not to. c300 4 magic 08. Bought new from dealer, serviced at dealer.
1 month after warranty, minor oil leak where the solenoid for the camshafts come and at the transfer case. After some "kicking and screaming" MB USA covered it.
18 months later, the car would not hold charge. Turned out to be the fuse box under the hood which in turn fried the ECU. 4500 USD, after a lot of come and go, I paid only 1/2 of the bill.
Conclusion.
Odds are you will not use it. If odds were that you will use it, the dealer/company would not be selling it. The Question is, how at peace would you be if you had big problem?
Keep in mind, nowadays, you will not take your car in for a ball joint or things of that sort. It will be your A/T, an electric module or something of that sort.
Ask yourself do you want to pay to sleep well? If yes, buy it? If you are buying it to "beat the house" most likely you will not. Welcome to Las Vegas!




Second one I got I used to the tune of about $2,000 in repairs on a cost of $900. Most of that was on one $1,700 repair.
My W212 is my first German. I decided to get an ELW as the repair cost is out of sight on these cars compared to my previous Japanese cars.
In Vegas terms, I had some house money so I made the bet. I may lose but it's all part of the game.
1) new bumper
2) center console cup holder wasn't sliding back properly - fixed
3) muffler rattling noise - heat shield?? - fixed
All problems that I failed to recognize when buying the car after a good inspection
4) just yesterday battery died at 9 pm. at 930 a Mercedes Benz technician arrived with my new battery
Oh and the use of a hassle free loaner
IMO the 2010 models aren't the year you want to go without a warranty




My main concern for the ELW was the airmatic, but after reading all the service bulletins applicable to my car, I realize there is more than may go wrong. That thread on engine replacement scared the $@#% out of me.
I agree with tiyyara is is for peace of mind. These cars are expensive to fix, but what is the likelihood that you will experience that in the one year to the tune of $4K... I would say slim.
While under factory warranty I had an intermittent backup camera problem.... the COMMAND system replaced under warranty because dealer says corporate Mercedes was telling them to do so. The part alone was over $2K.
Also scared of the potential engine problems with the 2010
good luck to the OP

got the ELW for 3 yrs/75k for around 2100.
