W212 2010 E550, 44k miles.

1. Recently changed out the front left and right CV axles, and front brake pads, and the front left brake squeaks after extended driving, and I’ve noticed that when I put the car in reverse and turn the wheel, there is a single clunk almost every time. After some research I’m not sure if it’s the brake causing it or if it’s the drivetrain, since it’s every time. What do you think?

2. One time earlier this week when I cold-started my car, the engine vibrated more abrupt than it usually does, and then every time after that to this point it has started up just fine. I’ve also noticed since then, that when I put some weight on the gas while driving between 30-40mph for the first time the car is running for the day, the engine plays a bit of catch-up before it starts gaining speed. Is this engine mount/transmission mount? Or another concern?

I recently changed my oil and also took it to a mechanic to get a once-over, said there aren’t any issues they noticed.

Let me know what y’all think.

Hey, long thread ahead.

I own a W212 E350 2010 (My lab rat), and I work in IT and I was thinking to get into cars coding and tuning as a side hustle to make some extra money.

I've learnt some main concepts:

- Features variant coding

- SCN coding

- Remapping

- The differences between C4/C5/C6

- The softwares Xentry/DTS Monaco/Vediamo

My questions are for those who can help:

1. Is C6 good enough? From what I learnt C6 is an after market invention and it can't do everything, but it seems to be the most popular and most spread world-wide so i need to know the limitations i will run into if i get one.

2. What are some advise and tips from people in this domain? Is it good? Is it worth it? What should I keep in mind? Whats something you wish you knew before you get into this domain?

3. Is my laptop going to be enough (along with my multiplexer) or will i need more advanced gear?

I need to buy a phone holder, and am considering an AC vent mounted holder... But I'm afraid it'd break the fins with time!

So does anyone have experience with this? Are the AC vents fragile or can withstand?

I got a nice interior and I want to maintain it after all 😁

My uncle has trusted me to find a good E350cdi OM642 prefacelift for him, since I already drive a W212.

I know a reputable seller that can get me a well-maintained one with full service history, so no worries there.

My question is about the production years and improvements that are or might be there.

The seller already has a very sweet and well-specced 2010 model in his lot. If my uncle were to go for it, he'd install the colour dashboard that the mid-2011 models shipped with (the info on forums leads me to believe it could be done with no issues).

I know the engine, gearbox, Airmatic, and anti-corrosion protection (or whatever Mercedes calls it) are the same

Are there any improvements/issues addressed on the 2011-2012 models against 2010?

I have a 2015 250cdi 4 matic
The car vibrates when i put in gear at idle . The vibration is felt in cabin ,doors , seats steering wheel and pedals . I changed mounts engine transimission it got 30-40 % better but car still vibrates . Anyone had this before ?
Front Cv axels ? Torque converter ?
Car shifts well and no vibrations are felt when car is moving

Thanks in advance

Hi Guys, I am new here. I want to get AirPlay for my car and I’ve seen that there are some options for the NTG 4.0 (Audio 20) but I don’t want to buy a bad one. Any recommendations or experiences?

Wife picked up a 2014 E350 4Matic a few months ago. I noticed the front passenger tire was slowly losing air every three or four days. Only about 3 to 4 psi. Brought it to my local Euro shop and they found a nail in the tire and put in a plug. I also had them set all the tires to 40 psi. So the very next time she drove the car after the plug the light came on and the tire had lost 10 psi. I thought thats weird so I pumped it back up to 40 psi and the next morning the tire was again at 30 psi. So I brought it back to the local euro shop and had them reinspect the tire. They said they cannot find a leak. The plug is good. They even took the tire off and put it in some bath to see a leak and nothing. They just threw their hands up in the air and said who knows. I didn’t have time to leave the car with them to search further. What’s going on? When the tire is off the car the leak goes away? And the strange part is it seems to stop leaking at 10psi loss. I’ve been driving the car for a few days after getting it rechecked and the tire is holding steady at 30 psi while all the other tires are at 40 psi. Is it a rim problem? Tire is messed up after they did the plug? The bead on the tire bad? I’m stumped.

I got a 2011 E350 with a 7-Gtronic Plus gearbox. Recently I noticed that my car has been shifting somewhat weirdly after cold start (or warm restart for that matters). Around 2 to 3 minutes immediately after an engine start, my car would upshift really late, like it just keep hanging around 2.1k-2.2k RPM without shifting, or then all of the sudden flare up to 2.4k-2.5k RPM before upshifting. Sometimes though it would just hang around 2.1k-2.2k RPM for longer like that before upshifting without RPM spike. After 3 minutes or so, it returns to normal (immediately shift around 2.1k-2.2k RPM instead of hanging). My pedal has been very consistent so the possibility of accidental throttling is ruled out. Shift however is very smooth and has no jerk, even during the occasional RPM spikes immediately after start mentioned. There is no RPM fluctuations under cruise either so I hope it was not slipping. Has anyone ever encountered issue before and if this is something I should take to the shop?
