w202 Cruise Control Retro Fit? [Archive]

GrahamC230K

Now I am happy knowing I am keeping my car long term, the only thing missing for me is cruise control (being a manual it was an option not standard). When looking at Audi TT's I had the mod already scoped (simple plug in stalk jobbie) at a cost of ~£150 so don't see why I shouldn't pay similar to do the same job on the C now it is staying.

I know MBenz (Steve) effectivly retro fitted this to his pre-facelift C250 manual, but it's one of the few undocumented mods on his website.

I have seen a facelift manual C230K with Cruise so know it is possible.

I also know for some models, MB do a complete cruise retro fit kit.

If this job is just the case of the stalk, possibly a new steering column housing to accomodate the stalk, the plugging in of a loom and perhaps a switching of it on via a Star diagnostics, I think I would like to go for it, assuming the cost is no more than a few hundred pounds top wack.

Can anyone help with the mostly missing parts to this?

What parts do I need?

I have discussed this with Shude, so thanks for your help so far, but with the new techie members we have on the forum recently, I am hoping someone may have the answer.

I really would like to have cruise and the speed limiter function (if that works on a manual) as I think it will help my motorway motoring and my speed fluctuation problems!

thanks in advance

Good for you . . . . sounds like a sensible mod :) This is the first car I've had with Cruise, and I would never buy another one without it now - especially if lots of motorway driving is needed.

I don't expect the parts are much more than you have outlined . . . . just the expertise required to fit it to OEM standard that will be a little more challenging to source !!

In my days of 4x4 driving there were DIY kits about that required the fitment of sensors on the drive shafts for speed measurment and something like a pump fitted to the throttle housing to adjust the throttle,and obviously a brain for the system and a stalk on the steering coloum,Things may have changed a bit by now but I rekon they havent changed that much.The sensors on the drive shaft may have been replaced by connecting direct to the speed pulse wire?

you can fit just about any system to your car and also buy aftermarket simple to fit kits here is a very good insight to fitting one

You are right Shude, I was just seeing if it was possible to source the answer without bothering him. I'll fire an email off and hope I'm less that 300 in the list of unreads!!

Well, I got a response from the email I sent to Steve. Well, it was from Steve's account, but not fdrom Steve - perhaps he has got an assistant!!

The response was, MB should do a kit to retro fit cruise.

So, I called Hughes, Aylesbury.

The guy found the list of retro fit kit parts after I explained to him some features were available as retro fit kits as oppossed to individual parts.

Parts Man: "Where did you get this info?"

Me: "Research on the internet"

Parts Man: "Oh, they might not be Mercedes Parts"

Me: "They are"

He advised that as far as the computer was concerned nothing was available for a RHD car. He did say he could see a retro kit for a LHD car up to a '98 year. However he said that had a note to say it did not include "controllers" and cost £508+vat.

He explained he could not recommend that part as in all honesty he did not know enough about it and that as a dealership they did not have much experieince of retro fitting parts.

He then went on to say that retro fitting options and features at dealerships is dying out.

Parts Man: "It's more of a specialist/enthusiasts area. If you are looking on the internet, you might find out more"

Parts Man: "We can't even retro fit Sat Nav to the latest models as a dealership, but I know it can be done"

Me: "Oh, you mean Command units?. Yes, I know people who make a living specialising in retro fitting them to just about anything"

I made a polite end to the call, making the guy sound like he had been helpfull.

Oh well, £500 is about double my justifiable limit and I call that a dead end anyway. Will have to loose that idea, unless anyone ever want's to disect their Cruise, so I can slowly gather parts from a breakers.

I'm at Steve's place now, he's looking it up on his computer.

He says that from what he can see in the electronical layout, you only need the handle - which needs to be plugged into the EIS (Electronic Ignition Switch), and then version-coded (at the dealer). He recently did this in his 2004 VITO as well..

This seems to be the part# for the handle you need: A2085450424

Let us know how it goes.

Oh, and according to this site: http://wwwsg.daimlerchrysler.com/Projects/wi/cda/etpl?ETNR=A2085450424&from=query&etpl_lang=

The price for a new one is 67.49€

£48 + vat - it's a goer!

The independant who is servicing my car today says he has done this before. He has the equipment to code it too!!

Also adds that he has previously cut the shrouds to accomodate the extra stalk before, so no need for a new one.

I'll report back when the job is complete - next week hopefully!!

You, you did.

The guy who can code it, thinks maybe there is one other small part required for manuals, but will check his system and give it a go anyway.

I assured him my contact (Mbenz) was as reliable as they come.

EDIT: My guy has confirmed stalk only required. Needs the car for about 1.5 hours to complete work - is going to give me a shout next week when he has a gap :bannana:

Plug, program and play.

I was just discussing with Fuzzer. I am not sure if anyone has cruise on a manual car that can confirm (or anyone that can be bothered to read the manual).

I am not sure I will get the speed limiter function. It strikes me that it could be dangerous as there is no kickdown switch below the gas pedal to overide it.

EDIT: - unless it deactivates if clutch is pressed.

Either way, cruise is on it's way :D

How does the speed limiter normally work? I assume not all cruise controls have this... at least, if my S320 has it, ive no idea how to activate it!!! :(

You push the stalk in and if youve got it , will spring out and a yellow led will glow on it.

Hehe, we tried this in Steves VITO last week - since it has no kickdown it doesn't override the Limiter. Doesn't seem like anything dangerous to me, it's just a matter of not using it ;) I've actually never seen the point of it anyway, but what do I know - my car was built back in the stoneage or so...

My wife's manual mini has cruise and it operates exactly the same as my W202 Merc. You can accellerate and when you lift off it returns to the speed you set. Fairly sure it deactivates with the clutch.

Surf Blau

24-08-2004, 12:56 AM

Cruise control in combination with manual trannys always have clutch-deconnect as far as I know - but maybe there's need for something similar to the switch found on the brake pedal since it is a retrofit??

Wish I had a limiter on the hire car I had last week near Stuttgart (Merc Mecca). The autobahn limit went from infinity to 60km/h for roadworks all in the space of 1km. I had no chance, the first I new was a large orange flash going off in my face which is slightly off putting in the dark. Oh well, at least the points won't apply on my clean UK licence !

...reminds me of trying to get info from MB to do the cruise control upgrade on my 1990 SL with ASR...couldn't be done they said as WIS only documents what to do on cars WITHOUT ASR...turned out to be the cheapest mod ever...just a stalk, plug and play...

On the UPDATED 202 with manual trans there is some coding onvolved and you might need a switch added to the clutch pedal but the upgrade won't be much more difficult then that...

..except if this W124 has ASR, in that case you only need the stalk like Steve said (which applies to all cars with ASR)..

Does this mean that cars that aren't equipped with CC out of the factory have the amplifier, speed sensor and throttle actuator already installed?

Yes, ASR needs this as well.. Kinda makes you glad you weren't an original owner paying through your nose to have CC as well...

GrahamC230K

20-10-2004, 06:00 PM

Well, it's true, a ~£40 part, ie the switch was all that was need to retro fit cruise to my '99 manual w202.

That and someone with the Mercedes equipment to "code it".

I have cruise but not the speed limiter functionality.

You need a Mercedes computer to code the fitment, so really not a DIY thing, but any competent MB inde could do it.

It seems that this old tread is up again.

It's really a nice mod, cheap also.

Please, since I'm wondering about, do you confirm that the modification require a competent Mercedes Dealer?

The part. number posted previously it's related to a RHD, but I'm quite sure it's same for a LHD as my manual one is?

I'd like to verify to my dealer with the right part number to ask them an offer for this.

Further, could you please explain me what does it means the "speed limit" feature?

Thanks a lot for any help. :)

GrahamC230K

29-09-2005, 03:19 PM

It requires someone competant, with a STAR machine I believe.

The speed limit feature is an additional feature on some cruise control equipped Mercedes - you enable it, set the speed via the stalk and the display on your dash and you cannot exeed this speed unless you disable it or use kickdown.

This feature does not work on my car, but maybe that is a good thing as it' a manual gearbox.

Ok thanks a lot Graham. This mod. seems cheaper as retrofitting than as factory option :D

Have you seen if the stalk part comes with relevant cable connection?

My worries are about Mercedes Dealer...to find the right part number and STAR setting.

...since when I asked info about setting to "the Netherlands" in order to hear "CHIRP" closing the car, they said it's impossible, only at factory!...but I know someone have done it. :mad:

One tip - I have a stalk for Cruise which has the speed limiter controls - which do NOT work. However, there is a different part which is the cruise stalk WITHOUT the speed limiter bit - this would make a neater install.

440 is tempomat (cruise control)

420 is 4-speed auto with cruise
423 is 5-speed auto with cruise
425 is 5-speed auto without cruise.

You need to find the correct combination of options, the cruise stalk will differ depending on which options were fitted at the factory. The catalogue just has a brief description and a line drawing...

I've been convinced! I have saved up for my bike, and now I'm gonna start looking around to get this done! I had a look at my 202, and I'm guessing the steering column housing needs too be cut, am I right?

Secondly, your car is the facelift model, is there any significant (to this mod) difference to the pre-facelift?

Thanks, Michele

Im thinking that yours will need some sort of actuator attached to the throttle housing to mechanically move the throttle cable,On the facelift car its all electronic.

Since that post I have discovered that .......

W203, W209, W168, W169 can have speed limiter and cruise control fitted with just the steering column parts added. However, you need someone like Steve to do the work on the newest cars as there is a restriction on the amount of dealer coding that can be done ex-factory.

The expanded Star Diagnose functions that Steve has can activate the

- Cruise control function in the MOTOR CONTROL UNIT

- Tempomat (speed limiter) function in any car with a display cluster.

I think the parts are very reasonable and come to something like 40 GBP for most cars.

As for the W202 ... not sure. Its worth fitting the parts just for the heck of it.

In all cars with "accelerate by wire" - (no actual pedal connection to engine) then the coding for speed limiter is entirely in the ECU (engine control unit) and in the instrument cluster.

You need TEMPOMAT activation in the cluster and TEMPOMAT + CC in the ECU. At the moment you seem to be reporting that you only have CC active.

There are 4 menu items in newer cars
--------------------------------------
- NOTHING
- Cruise control
- Cruise control with Speed limiter
- Distronic

The only difference between autos and manuals then is that the auto will shift gear in both cruise and limit but the manual will plod-on in whatever gear you select.

AARGHH! :devil: Up-dating for my 1998 manual W202.

Went yesterday to the Stealership. They said it's quite impossible/expensive to retrofit tempomat to manual W202! Because this is not indicated in the list of after market modification they showed me!! :( I said to better verify because already done with a few amount of work and money, I said I have seen photo of this from a nice MB English forum!

They showed me a schema with all the necessary components I need: cables, electronic brain units and the well known steering rod. I said that 99% all the components are already factory installed, I should need only the rod and some switch on the pedal may be.

So please my question is: does someone (Shude or GrahamC230K or both :) )know/show me the cable and el.components involved so I can look if they are present on my car? :)

I'll really appreciate any help from yourside.

Thanks a lot ;)

Hello everybody

Re-activating the thread again.

After reading all the posts I really want to go forward with my cruise control installation in my C200 CDI (W202) year 2000. I brought the car from Germany three years ago (LHD) and I really miss this option.

My car has BAS, ESP,ABS,electronic throttle and manual transmission.

It is suppose just the stalk to get CC in my car? As mine is an electronic throttle equipped will I need to fit just the stalk? Thanks in advance
