Has anyone ever succesfully done a speed limiter cruise control install on an 04 USA spec C 320 coupe? Ever since I drove a car in Germany with this feature, I've always wanted it for my car. So, I ordered a limiter cruise control switch from Steve at MBenzML, got it in no time, (great service Steve!) installed it in my car, and that's where the good things ended.

Steve told me that the coding would be in the Instrument Cluster, but I have had no luck there at all. I even tried changing the coding to a different country, but nothing there either.

I checked the EIS, and nothing there about cruise control either.

In the steering control module, under actual values, it recognizes all of the functions of the limiter switch (and cruise control too) so I believe that the SCM is sending out the message, but nobody is listening.

My biggest fear is that the coding for this is in the engine management, which may mean a dead end because of the doggone SCN coding. I don't know yet, I'm hoping that maybe one of the members here may be able to help me.

Thanks in advance for any advice or help you can offer!

hi Mike,
I would like to do this too, but since my C320 Coupe is a 2003, I might be in a far worse-off position than you.
I sometimes wish I could get a whole new 2004.5 Coupe instrument cluster and SCN coding to go along with it, so that all the options are available.

I don't know Carlos, you may be better off without SCN coding. It seems like it locks down the version coding of the cluster or engine management to what Germany says you should have. When we do the IMS install on your car, we can check and see if the possibility is there.

Never give up!

LOL !
Cheers mate !

I have coded sunmans limitter a while ago...wasn't that much of a hassle and didn't need anything at all besides the stardiagnose...but must say that I coded it from a diag menu that is available in engineering mode...

carlos - shouldn't be a problem for you to get that mod done next time around...Mike, if you are in california as well, I can probably help you out with the coding on my next trip.

greetingz,

what does said speed limiter do?

mbbodytech

The speed limiter is useful when installing snow tires on your car, so that you don't have big problems. In my case, snow isn't a problem, but I just think it's a really cool feature.

Saprissa

Thanks Steve !
sounds good
any other European Coupé toys that I don't know about ????

Mike,
hopefully this Saturday we can do the IMS thing. Let me know.

The speed limiter is standard over here. Don't really find it useful, as compared to cruise control (also standard). Given a choice, I would prefer to have Distronic instead since I tend to drive too close to the car in front before I know it...

What about the passenger seatbelt warning. Kinda fun, the first time around with groceries in the front seat and the warning in the MFD.

Or if the BOSS decides it isn't necessary on a short trip.

Is the speed limiter "distronic"?

amdeutsch

Yes. It limits the distance traveled in a given amount of time by virtue of being a "speed limiter". :p

mbbodytech

Steve,

That sounds great to me. I don't live too far from Carlos here in SoCal, so I would really like to see if you can get this thing working.

I'll be looking for the info on your next trip!

yes i have that feature in my car. Can preprogram a set speed limit and not exceed it. it MUST be done with a DAS capable of Engineering Mode as Steve has. THe cruise lever pushes in to activate it. I have my limit swtich assy if anyone wants. email me drsunilpatel@mac.com

Saprissa

you've got mail !

dgwee

No its not. The speed limiter is call the "Speedtronic".

The "Distronic" sends a signal to the car in front and if you go too close the Distronic either buzzes you or brakes to slow down your car.

Unfortunately its only available on the E, CLK, S, CL and SL.

JohnCL

Distronic can be done on the C as well if you have $$$ and time. Sunman has it on his C-sedan.

raunen

so what's the difference between a speed limiter and cruise control?

mctwin2kman

The Speed Limiter is exactly how it sounds. It limits how fast you can go. Basically instead of hitting the cruise and letting it do the work for you, you set the top speed limit and floor it! You have to hold the gas from what I understand!

Saprissa

Speed Limiter (speedtronic) is now on my scheduled mods list.

Distronic (DTR) is on my "wish list"...
I believe the eye sensor, and control module are the most expensive parts.

however, my MFD shows the DTR icon:

SUNILP

all 203's show the DTR icons. Both the DTR and the car chasing another car icon. It can be fitted to all 203's if you can get parts for it. Most 203's will require changing the ESP/BAS module in the engine compartment along with new power steering cooler lines and top radiator bracket. see my pictures for more details. http://homepage.mac.com/drsunilpatel/PhotoAlbum14.html

dgwee

The first part is correct, it limits how fast you can go. If you set your speed limit at 100km/h, your car will not go faster than that... HOWEVER, if you floor it, then kickdown will override the limiter, for example, if you wish to have a burst of speed to overtake, etc.

SUNILP

To enable the kickdown to override the limiter, it requires SCN coding of the MPFI module in the engine bay. If simple IC programming is done, then the limiter will function as a limiter w/o kickdown feature as I have.

mbbodytech

Are there any choices for SCN coding the engine management? I thought that whatever the master computer in Germany kicked back is what you got, unlike SCN coding for instrument clusters, where you input an option code and then received your SCN code in return.

Saprissa

can someone post a picture of what the Speed Limiter Assembly looks like ?
is it something you can see once installed, or just an inside switch, that is activated with the cruise control stick ?

thanks !
