r/w204

I’m looking into possibly getting a 2014 c300 with 100,000 miles on it. Can anyone help me with the reliability or tell about their experiences with them? Thanks

So I’ve had the car at two separate dealerships, two times now with the complaint my car is rough shifting between 1-2 & 2-3.

I have an XENTRY clone & I can perform the teach-in adaptations per gear & it smoothes it a lot/entirely but the bumpy shift between (1-2 & 2-3) always rears its head after some time. I was hoping the dealership would find something wrong with the software or something each time but never come back with anything, never find any faults & they always reset the adaptations without performing the re-learn, so they return the car stating to them it shifts quite nice, but its quite literally slamming through the gears until I, MYSELF adapt it again properly. Completely stumped, i’ve checked the fluid multiple times/topped it off but still not getting anywhere.

Any ideas?

*I will also add, once properly adapted/re-learn performed, this gear change issue only happens on LIGHT throttle, below 2000 rpm to be exact. If you drive aggressively it’s smooth.

After looking through an alternative Mercedes OEM part catalog I've finally figured out what the difference is between these cars.

Its not the turbo charger like some people suggested on my last post, it is 100% the injectors. The C250CDI utilizes injectors with the code 2887 whilst the C220CDI doesn't.

The OEM turbo codes are still identical between the two models. So it is literally just the injectors that are different.

For some reason the other catalog I used didn't display the 2887 code for the C250.

I'm gonna make an educated guess and say the difference between the 220 and 250 injectors is the nozzles and not the injectors themselves. Which if true is fantastic news because you can buy replacement nozzles for a fraction of the cost of complete injectors.

I'll try and test this theory in the coming month or two by swapping out just the nozzles for 2887 nozzles, bring it in for a remap and see what the results are. With any luck, she'll be in the C250's power range.

Getting the P0128 code intermittently saying the car's warming up too slowly and the battery is brand new too. Had the car for a few weeks and done less than 100 miles. The dealer I bought it from put green coolant in it which after doing some research seems to be used for the diesel models. Is it worth getting a flush or should I just get it drained and refilled with the correct stuff?

*less than 1000 miles sorry

I've been looking at a listing for a 2007 C200 with 350k km (hopefully real). It looks well kept and no wear and tear. It costs around €5500 when converted from my country's currency, which is a standard price for C classes here.

I checked carVertical and it has nothing on the car.

Also, it has all the features that it can have.

I would have my mechanic friend come with me to check the car on the spot.

sunroof still opens and closes fully, but it lost the one-touch behavior. Instead of pressing once and letting it do its thing, I have to click the button like 10 times to get it all the way open or closed, each click moves it just a tiny bit.

It’s not stuck, mechanically seems fine. Just won’t do the automatic full travel anymore.

Anyone had this? Tried holding it close / open for 10 sec at a time but it didn’t work.

Hey everyone,

I recently saw a W205 sedan rolling on a set of 19-inch Keskin KT18 wheels, and the fitment was absolute perfection. Not too big, not too small, and definitely not looking like a harsh race car. It just had this incredibly clean, classy, yet sporty vibe. The proportions were spot on,there was still a decent amount of tire meat, and it just looked so well-balanced.

Now, I’m about to pull the trigger on a W204 facelift, and I desperately want to achieve that exact same elegant, "perfectly proportioned" aesthetic.

But here is my dilemma, and I really need your expertise on this:

Since the W204 has a slightly more compact body than the W205, I'm worried about how the 19-inch setup will translate. I want to replicate that exact same clean, daily-driable look where the wheel fits the car perfectly, without it looking disproportionate or overpowering the body.

So, W204 experts, please help me out:

1. Will 19" wheels look just as perfectly proportioned on the W204 facelift, or does the smaller chassis mean I should change the size?

2. Should I go for 19 inches to get that same full look, or is 18 inches the better sweet spot for the W204 to keep those classier, well-balanced proportions?

If anyone is running 18s or 19s Keskin KT18s (or a similar style) on their W204, please drop your thoughts,and pictures if you have them!

Appreciate any advice or fitment tips you can throw my way. Thanks in advance!

So I've started to replace the factory restrictors and silencers to enchance the supercharger whine. I've replaced the supercharger baffle (kompressor to intercooler pipe) and the 90° from the intercooler to the throttlebody.
The car is still very much daily driveable and you only hear the whine when stepping on the gas (ideal), but of course I'm not done.

Next on the list would be piping from the airbox to the supercharger, but since it is quite a bit more work to get to it I was wondering if anyone had done this and had the diameters on hand.
I tried to follow a youtube video but the measurements that were provided proved to have alot to be desired.

This would save me an extra assembly and disassembly step since I most likely have to order the piping.
