I get this fault in my Mercedes C230K sportscoupé - I went to Mercedes they used 4 hours, but came up with nothing...

They dont know what it is, and they sure dont know how to fix it....

I tried another Mercedes place, they had the car for 1 day, and still they couldt find the fault....

I provide a picture of what it say;

Does anyone know what this is:



Thank you all!

 

Doesnt anyone know anything about this?

 

I think it's your cruise control. As that is the only thing I can think of for that symbol.

 

Haha. "CR. CTRL" - It'd be my best guess too. Are you still under warranty? Speedometer indicates you're international.

flip

 

I am not under warranty anymore, yes it could be the cruise control or speedtronic in my case ( Its a tool so i can set a speedlimit so the car dont go faster than that), but mercedes say they cant find the error, so that doesnt help me alot....

The error come and go as it desire, you guys know what can trigger it? Or how to fix it?

And yes i am from Europe

Ps. I just changed breakes on the car, about 10days ago - could that have done this?

Today this fault came up again, i pulled over, and turn the car off and on 5-6 times, and then the fault was gone - When this fault appears the car become very slow, it is not limp mode cus it goes to 5th gear, but it takes a long time to go from 0-60.

 

The screen says exactly what it is, its the speedtronic control unit!

 

The speedtronic control unit?

Perhaps its Mercedes in Denmark and Sweden that are stupid and can't figure this out..

But does this control unit have a part number or anything that can ID it, so i can tell them at MB, so they can change it.... as i said they couldt find the fault.

 

Escalate your complaint beyond the technician and service advisor... go to the service manager or dealership owner. There must be some experience within the European dealership network that has seen this problem before and reported it via service campaign number.

 

Apparently it's not just the U.S. getting such ****ty support from MB...

 

hahah i agree, i used to think MB had great service, when i FIRST got my cars
but now i them and they hate me!


btw, like said above, i guess its the "Cruise Control"

well i mean if you said you changed the brakes, are the fitted right? did you change the sensors? maybe you F-ed up while you changing the brakes. If I were you, try removing the brakes and sensors, then reinstalling them. maybe thats whats wrong.

well try USING the Cruise Control feature...does it work!?

 

Which sensor are we talking about here? Is it possible to change them also, if yes, do they have a part no. i can use at MB?

Where are the sensor located at the brakes?

 

Anyone... ??

 

it is a cruise control/speedtronic problem indicated. IF your dealer can't figure it out, they are idiots. Any error is stored in the systems memory and they can pull it with their star diagnose system. Could be the cruise control actuator.

 

Just curious, did they charge you for the time they spent to tell you they did'nt know the answer?

 

No they didnt, first they would, but then i talked a bit with them, and they said " okay a good will from our side " - Like they did something good..... i would have paid big $$$ if they could at least identify the damn problem...

 

Speedtronic is a group of three systems to my knowledge. 1. Vehicle speed sensors and instrumentation readout, this is also piggybacked in by the ESP computer (they're actually all on the same computer, but it reports to the ESP computer). 2. Cruise Control. 3. shucks, I can't think of the last one, lost my train of thought.

There are a few possible problems, maybe the speedometer or speed sensor is not registering correctly. Are any of your tires more worn out than the other tire on the same axle? Check your tire inflation pressure.

Cruise control may have problems.

Seriously, good luck and be safe. Follow MB-Bob's recommendations with the complaint process.

 

So i had a apointment with another MB dealer workshop. Getting up early in the morning, going to my Parking house, its a big house where lots of people park their cars, you need a uniq card with a uniq code to get in... and there it was my car, with my windows smashed and everything even the command system was stolen - What idiots there are in this world.....

Unbelievable my bad luck, this is the 4th time in 6 month i had problems with idiots taking my stuff and smashing my cars......

Oh well, i did a complaint on the other MB company, and got a new time to get my car checked, i will keep you all updated.....

 

UPDATE


I went to MB in Germany, i was sick and tires that in Sweden and Denmark they could not find the error on my car.....

So after six hours they came up with this, the digs. computer they hook to my car shows NOTHING, it says that there is NOTHING wrong with the car even when i got FAULT in my display, i was getting really pissed off!

Then they told me that they THINK its the main computer system box part number; A1111533679

They THINK it is faulty, but they are only 80% sure, they want me to change it, its cost 1000$ to change and program, and if it is not this that cus the problem, they its just BAD LUCK, i have to pay anyways.....


OMFG what is this!

Is this Mothafu...... skoda i went to ? or is this MERCEDES BENZ? Maybe if i go to MAZDA or OPEL and take my MERCEDES there, they can tell me whats wrong? Maybe Fiat?

What do you guys rekon? Could it be the main computer system? The fault does not show up when they scan my car, and thats why they THINK its that....

 

Personally what I think it is ........

Observe the following.

- rough roads > error = damage to wheel sensor, ESP repair kit

- new wheels > error = wrong size wheels, install AMG sizes or normal wheels

- turning on tight road > error = damage to steering column spring, replace part

- switch malfunction > test with diagnostic

- hot or wet day > error = possible damage to main ESP harness

If your brakes, ABS and ESP are working (no error) then it's probably the rims.

 

Everything is working, and its the original AMG rims that came with the car when i got it with tires that fit the car.

I am convinced it is some kind of electrical error..

 

Then it is time to take the wheels off and look at the condition of the wiring harness for ABS function.

 

But if its about the ABS wire thing, shouldt the ABS light go on then?

 

No, the ESP light should go on.

 

But its not, everything seems normal.... Anyways i will try to take the wheels, brakes, everything off and refit them again after i checked everything.

 

There is no speedtronic control unit. The cruise control / speed limiter function is controlled by the engine management computer, and the speed chosen is relayed by the instrument cluster. That's why they wanted to sell him a new engine control unit (at least I'm guessing that by the part number starting with a 111 for the 111 engine)

I learned a lot about this when I tried to retrofit the speed limiter to my US spec C Class and got nowhere. It is a part of the country coding of the engine management computer, and with emissions and such there isn't really a good way to fix this.
