2014 ML350 Bluetec - Maintenance Question

Hello Fellows:
Just bought a 2014 ML350 Bluetech (Diesel) with 100K (KM)on it. I am loving the vehicle and the drive. Car proof shows its clean and maintained by Mercedes in 2015 and 2016 however no record for 2017.
Normally, as a good practise whenever I have bought a used car, I have done the following: Oil change, Transmission oil change, coolant, battery check, etc etc,
Now, I am new to Mercedes and Diesel, so just looking for some advise/guidance as what maintenance should I do before we start driving it regularly. Any check list would be much appreciated.
What regular maintenance is required (other than dealer recommended) and anything to keep in mind when driving diesel?

Thanks a Million!
AMK

Km or miles?
I too am a relative newb, as this is our first MB and first diesel. I ignorantly (or innocently) believed that by spending the bigger bucks for a Mercedes, I was purchasing dependability, reliability and long-term piece of mind. I realize now that I wasn't" necessarily" correct.
Not sure you know what you got yourself into, but your idea of fluid changes is a good one.

Read this to better understand the Blueteks' intricacies. There are "some" (meaning one) here who may argue with this, don't let that faze you.

In short, replace engine oil/filter often, pop your belly pan and engine cover during summer, keep your Adblue tank full in winter etc...

I don't agree with the assessment. I have had a 2011 GL350 and now a 2014 ML350. Total of 7 years and 400,000 plus kms of absolutely trouble-free driving. Lest you think I baby'd my car, I assure you I did not. I towed an RV every other weekend in the summer, commuted in Toronto's rush hour and EVEN drove to Fairbanks, AK!

PS: No time to read the online book (linked above), too busy driving!

Your post is encouraging, KayVee. I (and surely DanD LOL) would like nothing better than to be wrong. What are you doing for oil changes? How often?

Yes it is ) Peter.
But 400K km is just 250K miles. Between two cars its not that a lot this days. RX most of the time goes 200K miles troubles free.

I have a hope every time when I pull my ML our of garage, the hope is there no oil on the ground ))

I have dilemma trade in BT ML for gas version before it develops some oil leaks or keep it till than. With trade in I have to add about 10K to a loan but car will have twice less miles.
On another had with 10K I probably can fix a lot of things with BT ML. Or it will last ))
This is also my hope.

Getting some positive and negative input here. However, still trying to stay positive. I agree with DanD, RX goes 200 miles trouble free. Merc in my opinion should do better.
Anyway, I just had car serviced (Not from Mercedes), an auto shop which has expertise in German cars (In Markham, ON), I had following done on my ML350 BT
1- Oil Change
2- Fuel Filter Change
3- Cabin Filter Change
4- Engine Filter Change
5- Ad blue, was low - refill
6- Bought an extra jug of Adblue
7- New Wipers

All this plus labour was 1450 CAD.
Now he also told me few things which I am sure gurus here must already be aware of:
Diesel engine likes to be run on high speed every now and then, reason being the condensation in the engine is the main reason of building sludge, when run on hwy, the engine gets really hot and helps burn the condensation, hence no sledging.
Also, he told me to add the AdBlue once every month, as there is apparently some coil/ or something which when gets exposed, gets corroded very quickly, which is expensive to repair, so this can be avoided by refilling the Adblue more so often.
Next service, I was advised to change the transmission oil, deferential oil, coolant replaced.
Let me know what you guys think.
Thanks,
AMK

Agreed on AdBlue - keep it full most of the time.
Also I was reading about keep diesel tank full too, helps avoid condensate.
Replace full filter every 20-30K miles top.
At some point I read about trany oil change. Some people suggest every 40K miles some once at 50K and its it.
Diff fluid, read Diablos post in here
https://mbworld.org/forums/showthrea...=699886&page=1
Personally I will do diff fluid change in a few weeks, car has 75K miles now.

The truth? Trade her in. No use obsessing every time you look at the truck. Myself, I think I'm starting to enjoy becoming increasingly anxious LOL

The truth is, I love the car and just afraid to lose it due to oil leak, slugged engine or something else.

Danny Danny Danny.....LOL

Follow Steven's Garage recommendations and cross your fingers.

As an aside, I finally sold my running boards to a gentleman who picked them up last Saturday. He has a 2014 BT with around 20k miles.
I went into the whole speil about losing the belly pan and engine cover in summer, frequent oil changes and motorcycle oil. He looked at me kinda funny and announced;
"I have a 2013 VW Touareg diesel with over 120k miles, never had any major issues with it."

So while I don't necessarily discount that these vehicles may be ticking time bombs, maybe we be overreacting a tad. I will nevertheless be following Steven's Garage recommendations, can't hurt.

I'd say don't do it. We had a '12 ML350 BT that we traded in for a '16 GLE350 gas. The GLE's updates as well as some additional options we got are nice but not a day goes by that I don't miss having a diesel.

You could've done all of that on your own for less than $200 (USD). I agree w/ brake fluid every 20k miles or 2 years on any car. I used to get the adblue fluid in a 2.5gal container from a VW dealer for $12 and all the filters from MB dealers selling them online.

SKW, I dunno how he could have done all that for less than $200 US. The OEM air filters alone are $120 USD. I do agree that it would still come out to wayyy less than $1400 CAD.
On the other hand, the vast majority of people who purchase an MB or Beemer don't do their own maintenance and would gasp at the idea.
