Test drove a new C43 - questions
Ordered August 2018, promised early October, showed up late December. Black package with Emerald Green paint. If you order, please get an actual color.....
Overall, love the car. For all the ragging about real AMG, you have proven Benz running gear, nothing is too exotic, and mine at least has been " a good one ". I've had to buy, I clearly drive too much to lease. I didn't buy the tire package. If you drive in pothole land, go with the 18's....19's only if you live where it doesn't freeze much.
The c43 is a willing accomplice, if you want to be "there"....bang, you are !
Runflats....if you lease, remove them immediately, put in garage. DWS or A/S 3+ first week. The RFT transmit a lot of NVH into the car, and as many have noted, don't absorb road impacts and transfer the forces up to the rims, which then bend. I had no tire issues, the horrid RFT wore evenly at least, but all four of my wheels needed to be trued before I installed a set of normal Michelins. The car is much smoother, less noise, and drives better sans runflats. Why Benz kneecaps the cars this way is a mystery. Do they save THAT much money on each spare tire they don't have to make ???
You'll appreciate the active suspension more when you get real tires on the car. Brakes are huge, you'll never tax them on a public road, even your favorite Reference Roads....
I did buy the 100k extended warranty, be sure to negotiate it, the ask vs. buy price spread was pretty big on my deal.
You want the uprated lighting and active headlights. Burmeister is very good for normal folks, there are always those who want more. Active Headlights are amazing if you do much night driving on unlit roads.
Surprisingly good gas mileage for a very fast car. I specifically ordered dark green-black trim for a low profile look, and de-badged the car. In my area, a C class doesn't really stand out, and I like having supercar performance in a plain wrapper-giveaways are the grille and the back clip/exhausts, but only geeks will know what you are rocking.... You can, of course, option yours to be quite showy, it's up to you....
In that vein, I have the PE, which I bought because it's a true dual with an H pipe and regular is a two into one back to two. I DO wish I could shut off all burbles and pops, because when you finally pass that row of brain dead minivans, it's not very stealth to pop pop pop on overrun...but it is fun when you finally get enough road to be rid of the guy with the WRX who is tailing you. PE doesn't change the overall notes, just the volume of the exhaust.
One quibble. I didn't get the full distronic system, as I didn't care about active cruise control, lane departure warning or having the car auto-park. This is the only way to get those small ultrasonic parking sensors on the car. Bundling this minor item with a package full of things I'd immediately shut off is a poke in the eye....thanks marketers. I still would have passed on the Distronic....but at 60 plus K, those sensors could be included. I got a GLS loaner, and in the big truck, same electronics, no distronic...but they had the beepers....
I'd do it again....

I also notice a typo from my previous post so I do want to apologize, you need a 21mm socket for the engine filter, not 27mm. The oil filter torque spec is 25mm
OR better yet, Here is the thread that I used: https://mbworld.org/forums/c450-c43-...-tutorial.html
Keep in mind this thread applies to pre-facelifted models I am not sure if Mercedes changed things for the facelifted MY19 and beyond models.
When looking to replace my '18 C43 lemon, I passed on a '20 sedan that was coming from South Africa because I know little about the build quality associated with that facility.
1) Brake pads and rotors replaced in first month of ownership due to irremovable rust, corrosion, and pitting on the rotor hats and on the face of the rotors themselves. All the damage occurred while the car was parked on the dealer lot, waiting to be sold.
2) Reading light buttons haven't worked correctly since day 1. Sometimes pressing the buttons turns the light on, sometimes it doesn't. Guessing it's a wiring gremlin. Never had it addressed because the dealer already tore up enough of my interior, which leads me to #3 . . .
3) Steering wheel and column had to be replaced in first month of ownership due to faulty injection molding; dark, greasy stains were leeching out of the steering wheel airbag cover.
4) Windshield wipers had to be adjusted because they were over-travellng in heavy rain and striking the windshield-side of the A-pillar.
5) White stains that looked like sweat stains on a baseball cap started oozing from all of the leather door panels on the car. Never had it addressed because they would have had to tear out all of the door upholstery. I just have to wipe the stains off every few months with a damp microfiber .
6) Whining noise from differential resulted in car being at the dealership for over 1 month. 3 replacement differentials were installed to no avail. Special case was opened with Germany; MB ended up installing "diff dampers" (aka cheap rubber bushings) to help soften the noise. Basically, it was a band-aid solution.
7) Steering wheel violently intermittently pulses/vibrates when driving at speeds of 70+ mph on the interstate. Feels like driving over rumble strips. Good triceps massage though.
8) Residual moisture freezes on the weather-stripping at the top of the windshield, and around the sunroof, in cold weather. This causes loud cracking and popping noises when driving.
9) Random squeaks and rattles from the interior, particularly the center console. Gloss black trim is so loose in several spots that it can be moved by blowing on it.
Other than that, the car runs. Which is a nice bonus.
I have most of the packages except driver assistant and heads up display.
First off, I test drove 2020 S5 coupe and BMW M440i before deciding on the C43. The C43 just felt like a better sport car, probably because it's a real AMG tune.
Performance exhaust is a must have for me and it sounds incredibly exciting. Drive unit on the steering wheel is also a must have, it looks really sporty and make changing drive mode easy. For the looks alone, it's worth the extra few hundred.
So far I've only driven 800km and still breaking in the car, no sport mode yet until 1500km (recommended break in sticker on my windshield). I purchased this car, not lease, so I intend to follow all break in procedures to the T. So far the car engine is becoming more and more efficient. I noticed mpg have improved significantly and expect it to get even better. For a V6 biturbo, this engine is really efficient. City driving so far I'm getting around 11km per liter in comfort mode after 500km of driving. I followed the same break in procedure with my GLC 300 and my fuel consumption is around 20% less than what is posted by MB for that car.
I did noticed a rattle on driver side probably around the rear speaker area. This might be a common rattle and dealers have lots of experience fixing. Very minor and will have fix soon. I also own a 2018 GLC 300 built in Finland and my C43 built in Germany does feel significantly better built (car just feel tighter).
Being a 2020, I believe alot of kinks has now been fixed already. So far very happy with my C43. The Audi S5 and BMW 440i just feels like a step down compared my C43. I could be bias but the engine is significantly better, exhaust sounds much better and the front end of the C43 just grips the road so much better as well.
Good luck with your decision. Hope this helps.



The Best of Mercedes & AMG



As for TModello's dislike of the car, then you did the right thing by selling it. No disrespect intended, but at the Ricky Nelson song goes, "You see, ya can't please everyone, So ya got to please yourself"
What did you purchase to replace it?

1. On the transmission I have read posts that what people thought were problems are not but related to a 9 speed that just doesn’t like feathering so slightly jerky at times. Haven’t heard and specific issues otherwise. Internet searches give it good reliability.
2. On the rims I can’t answer. Not sure if pot holes are playing a part. Maybe someone else can answer.
3. Got the premium sound system and agreed with the forum that the mids are non existent. Bass was ok for me. But I don’t think it’s as bad as some of the other systems I have heard like in BMW. I thought that sounded worse. There is a fix to change the factory amp with a specific aftermarket one for $1000 that maintains factory functions. Not decided on it yet.
4. Maintenance does not seem any worse than any other car. In fact the oil filter is changed from top of the engine in this car which is easier.
5. I don’t think the dealer can void your warranty if you do maintenance unless they can prove you broke something. I picked up the 4 year maintained package after he gave me at 50% off. Will do myself post that.
6. Seems some posts with others having rattles but not me. Yes if I run over those speed bumps you will hear things but I go slow on them and it’s fine. Otherwise no problems for me so far. Time may tell me different though it feels solid.
7. I wound up just getting it fully loaded as it really only added another 5k from want you have. But you have the most important for looks and functions. Get the digital cluster also. And make sure you have the package that gives you the upgraded console screen size.
But I love it when a stupid Tesla pulls up next to me and he can’t get in front of me. Don’t get me wrong, Tesla is fast due to electric but this car is fast enough to keep up...
