r/W212mercedes

Just pure curiosity and wanting to see how much other 212 owners drive across the country/world 🙂

This would also be a good place to note any major services you did at certain mileages so we could inform eachother on what things are more prone to failure than others.

I have ~83,500 miles and I drive about 2,000 miles a month. (Bought the car in August 25’ with 66k miles)

for my 3.5 V6 the services that were important around the 80k mile mark were the upper timing covers, cam sensor o-rings, and the rear PCV cover.

My general service intervals -
Oil change: 5k miles
Cabin + Air filter: 10k miles
Trans Service: 40k miles
Diff Service: 40k
Spark Plugs: 60k miles

Hello,

My parking sensor goes off when I start my car and won’t turn off until I press the P button on the dash. I’ve owned the car for a few years now and this just started happening. Any suggestions on how to reset or what could be ? Also the trunk close button stopped working but is still lighting up as it has power. Not sure if related.

Thanks for any info

Upholstery is a completely different beast than mechanical work..

At least for the seat, can I simply buy a replacement online? I just remove the seat and should be able to access the bottom to take off the whole cover?

Or is there custom sewing involved?

Cannot find Tyres

In 🇳🇱, all seasons tyres are most practical.

I want to find all season tyres for my W212 but I cannot find the same models for front and rear, allowed setup with current 18” wheels is following:

Rear: 265/35R18
Front: 245/40R18

Alternative is to downgrade to another allowed 17” setup with 4 x 245/45R17. Then all-seasons are much easier to have from same brand

Recently took it to the mechanic and The battery (new battery recently) + alternator was tested on start and idle to be fine (also replaced alternator two years ago)

I had a loose negative battery terminal bolt, but that was fixed, and now it’s still showing up this alert a couple of minutes after starting the car.

Any diagnosis or fixes? Maybe serpentine belt (it was replaced a 2yrs ago) or maybe timing tensioner?

Thinking about trading in my wagon for a Prius

As the title says I’m thinking about trading in my Mercedes e350 wagon for a 2024 Prius limited. I recently took a job offer that would have me going out to California from the Midwest and working all over the state. Work is paying for extend stay hotels because I’ll be bouncing around every few weeks for about little over a year. With these gas prices even here at home it cost $100 to fill up with 91 so I can’t imagine how bad it will be out there and the whole purpose of this move is to make a good amount of money and be able to settle somewhere after. I would get a beater but with all the bouncing around I plan to only bring one car and I want something reliable and safe so while I’m at work the wife can drive it around safely. Obviously the main reason I’m leaning towards a Prius is fuel economy but I also really like the look of the 5th gen and the lane assist would be nice for long drives. I feel like my wagon is the perfect roadtrip car just not for that state and I don’t know if I want to drive a Mercedes in California for safety reasons. I’ve never been to California so you can call me paranoid I’m here for feed back. It will be dog (50lbs pit), cat, wife and I all traveling together will we feel to crammed? Any better recommendations? I also plan to keep it as a daily driver once we move out of California. We plan to only bring necessities we figured 2 suitcases each possibly just 3 for both of us I also have a roof box that I would bring too.
Do you think a Prius is the right move?

I should add that I love my wagon but it does have 100k and would plan to get a newer e36 once we settled.

Hello yall,

Oh and since im here typing then aswell might ask if any of you know why the display shows "Bluetooth device paused" when it isnt, it just seems bugged/glitched for some reason.

Cheers!

There are several discs to choose from. 28 or 32 mm thickness & 295 mm or 322 mm diameter etc etc.

It has the Anniversary special with the Classic interior & Sport exterior package. 18 inch rims and dual exit exhaust.

The front discs has drilled holes and the rear discs are solid.

Is there any major difference in the suspension between the suspension in the luxury package cars vs the suspension in sport suspension cars aside from the struts and shock absorbers?

Hello dear people of reddit I am on my wits end and I come to you for all your infinite wisdom.

So During a brake bedding procedure, I hit a significant pothole on the driver's side while under heavy braking( the pot hole bent my rim and also loosened my outer say bar link). While the brakes where getting hotter and hotter the pedal became softer. but then after that I drove on the high way and then around the city but when I still press pedal I have to press it 85% of the way for it to actally start breaking

Here are my current symptoms The pedal is springy/spongy; it requires 2–3 pumps to reach a firm height but travel remains long. It does not sink to the floor. When the car is off so I dont think its the master cylinder.

The sponginess got progressively worse as the brakes got hotter during the bedding run.

Calipers have been torn down and re-greased. Rotors spin freely at all four corners.

What i have tried so far I have re greased all the slid pins and all the hardware.

I bled all the break fluid from all for Calipers and replaced with new stuff.

I also check all hoses they move a very very small amount when breaks are applied.

No leaks and the brakes fluid level does not drop like over night and no leaks under the car.

Do you think maybe air has gotten in to the abs system,

Or one of the hoses have gone bad internally?

I am really stumped here i really hope you people are able to help me.

Thank you for reading all this 🙏

Hi everyone, I’ve been getting a malfunction warning on my dashboard for a while now. The issue usually occurs when the car is cold in the morning. When I shift from Drive (D) to Reverse (R) while maneuvering, the car sometimes jerks or slightly accelerates on its own while reversing—even when I’m not pressing the gas. Shortly after, the malfunction warning appears, and in some cases, the engine even shuts off.

When I scanned it, I got error code P060600 (CP48), but the code doesn’t show up consistently.

So far, I’ve replaced the 12V battery, changed the transmission oil, and had the software updated at the dealership, but the problem persists.

Has anyone experienced something similar or have any idea what might be causing this?

Tune for 2015 e400?

I have a 2015 e400 4matic w212 with 125k miles.

I gave it a full suspension refresh, installed high flow intake, staggered wheels with performance tires, and im about to install 4 piston brembos.

This car has the twin turbo m276 engine. It makes 330hp 350ftlb torque.

Other variants with this engine like the c43, e43, and 450 models push closer to 400hp.

It would be nice if I could make this car closer to 400hp but I dont want the car to destroy itself. Ideally I would like to get over 200k miles out of it.

Has anyone done a stage 1 tune on an e400 while sustaining reliability? What is my best option for a tune?

I was thinking about piggyback modules like the racechip but those have some mixed reviews about their power gains. I dont want to take it to a shop and want to tune it myself without a dyno. What's my best option here?

Should I do the tune at all or leave it stock? I feel like this car could handle a lot more power but I mostly drive it in eco mode anyway. It is my daily driver.

Best OBD2 scanner for Mercedes e350 w212?

Hello all —

Writing this on behalf of my husband who’s currently in Syria; I currently live in USA and am planning on taking an OBD2 scanner for our car with me. He’s had issues with others in the past (tech issues, features not working, connectivity issues despite assurance it works for our model of car prior to purchase), and since I can’t really return it after such a long trip if it doesn’t work, I want to be sure that this will work before we invest in a good one.

I figure the best place to start is to come here and see if anyone has firsthand experience with these, ideally with the same model of car - Mercedes e350 w212 (2010)

I appreciate your responses in advance 🙏🏼🙏🏼🙏🏼

Location of air quality sensor and humidity/temperatur sensor

I have a faultcode regarding the air quality sensor and humidity/temperature sensor. I have looked online at a diagram of where the humidity/temperature sensor lives, and it says it resides near the rearview mirror undernath the cover for the cameras. I took off that cover and i for the love of me dont see the sensor whatsoever. I even took off the overheadpanel and nothing. I know how the sensor looks based off the pictures ive seen online, but im struggling.

In regards to the air quality sensor i have genuinely no idea where it sits.

2009 Pre-facelift w212 sedan.

I appreciate any help.

W212 strange electronic gremlin

Hi W212 drivers!

Recently I encountered strange problem with my 2010 W212 diesel.
Happened two times in one month...

first time when I selected reverse and car stalled...check engine light on and this sign on the dash
https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSqXd-CZzCA1D5BlC9CKXKrSixXCBcxO4pJMQ&s
after turn off car started normal and drives perfect. Check engine light goes off by itself.

Second time during driving....car goes to limp mode and check light goes on. Went to service to diagnostic and it says somekind of communication error.

What to check? Anyone had same issues?
