ML350 service quotations
mark couple years ago. Thank you all and Happy New Year!
1. Spark plugs - $775
2. Transmission services- $900 ( at 60,000 miles)
3. Front brake pads + 2 front rotors - $1,125
4. Rear brake pas+ 2 rear rotors - $1,025




Reasonable? It does not matter.
You need to find an honest independent MB specialist. Ask in the forum for one near your area.
The 2015 ML350 is very similar to 2012 ML350, and I did the spark plug replacement myself following YouTube, and some posted instructions from @chassis . Cost = spark plugs + appropriate spark plug socket + patience. < $150. MB procedure by the dealer requires more steps, and more parts (gaskets + more error prone to me).
Transmission service: sister's ML350 got serviced for 120K miles with an Indy here in Tampa two weeks ago, transmission, rear differential, front transfer case, brake flush @$1200 (including all fees and taxes)
For brake parts, you can look at FCP Euro (not sponsoring anyone here) FCP Euro: 2015 ML 350 - Brake parts . Take your pick for parts + $200/wheel labor and still $1000 below the dealer's estimate.
You NEED an honest Indy, or you will be working to service the car, not the car to service you.

2. Necessary
3. Up to you - is the pad wear indicator light turned on?
4. same as 3
NJ + post pandemic means prices are higher on average, and higher than what they were 2 years ago. Having said this, $900 for transmission service is too high. $775 for spark plugs is too high, but it was around $600-$650 two years ago at a dealer, so maybe $775 in NJ post pandemic is about right. I DIY so wouldn't pay any of these prices.
If you have the time and desire you can do everything easily, except the transmission service. That one is a pain even for intermediate to advanced DIYers. I let the dealer do that one.
Call another dealer, and at least one indy in your area. 2012 with 50k miles = out of warranty unless you have ELW. In any event, no worries about where you get the car serviced. Just be sure that you do get all of the services, when they are specified according to the maintenance booklet (in the DIY in my signature).

Stealership = Dealership

On the brakes, my W212 is @90K miles on original brakes and I do not drive it softly, so I am spoiled compared to SUVs which are heavier, and 4MATIC plus with Automatic Lane Recognition (sister's is currently on the 2nd brake set @120K). But, if the brakes service is worth up $1000+, I will definitely double-check them even if Indy say is ALL for $1000. Perhaps you have more mileage left which you will be putting into the trash bin.

Now i am wondering why my dealer charged so much for parts compared to FCP site you mentioned...

Sounds like the dealer is trying to fleece you. Surprise, surprise. Get the spark plugs and transmission service done at an independent shop.

Front Rotors + pads, Genuine MB ~$690
Rear Rotors + pads , Genuine MB ~$630
and to be honest, a few months back when visiting an MB Auto Nation dealership parts department, there were several Duralast (Autozone brand) boxes with brake parts: pads, rotors, etc. on the floor for cars in the shop.
I was shocked.

Three months later I had a full 4 wheel brake service done at the same dealer. Labor $845.00 Parts $1393.10
Yes, that's very expensive and, no doubt, could have paid less at a local shop. Your quotes are comparable to the high prices I paid.

B. For #3 front and #4 rear rotors, I would go with Brembo replacement rotors from newparts.com (a.k.a. partscontainer on eBay), then purchase OEM pads from one of the online dealers as stated in A. above.
C. Then take all parts and have your Mercedes dealer install them. You will save at least 30% plus tax vs. prices quoted by your dealer with their greatly marked up parts.








1 - Genuine MB parts (with the Star logo stamped),
2 - MB/We certified parts (our own profit margin). MB cannot police them for every part they sell.
3 - Not from us, do not install
That is, the fact the parts department provides the parts, does not mean they are MB Genuine, for example, Brembo or Duralast
Similarly, some shops have a "not in the books" repair policy that they will not do anything that is not stated in the books. Their creativity is ZERO. They do not question anything, mechanic lambs.
