Guys,


Am wondering IF anyone knows for sure if a 2007 CLK 550 steering wheel (with paddle shifters) will fit a 2003 SL500 ? My main interest is whether the central splined steering shafts are interchangeable in "depth and diameter wise".


BTW, I am NOT interested in using the paddle shifters nor any electrical compatibilities just IF the wheel shaft/splines will fit ..


Any useful info appreciated,


rwm

To be correct repeat correct you will need to post the VIN's for your car and the donor car, if you don't know the donor VIN than provide the correct part number for the steering wheel!!

Ron Martin

Many thanks for the response.


Am currently in South Florida without either car...till this weekend ...I will check the VINs next week and get back to you - IF you are still willing to help out..


BTW ..are you in the Orlando area ?

Not to worry---we will be here---yep orlando--tampa area--mobile diagnostics!!

Ron Martin

Morning "Plutoe",


Am back in Tampa and have the VINs


My 2003 SL VIN is WDBSK75F63F060311
The VIN of the CLK 550 possible donor is WDBTJ72J47F207344


Am not in a great hurry.. you seem to have the knowledge I seek ..


Please send a PM email to me and we can discuss the possibilities ..

Thanks, rwm

After a look in EPC, it is my guess that the donor wheel is not compatible--to review all the fit\color differences visit any dealer and look at 230 460 05 03 9C67(yours) and 209 460 34 03 9E37

Ron Martin

Thanks - You seem to very knowledgeable in Mercedes electrical systems.. I am trying to complete a VERY "special project" on my R230 that most of my friends say is impossible - which makes me work harder on it ..IF ..IF you are willing to help me in the schematics of the steering wheel connectivity, I would appreciate any and all advice / help you might offer..


As you know my name is Ron Martin and I live in south Tampa and have owed various Mercedes for many years - but mostly W107s..
How about thinking over my request and then send a PM to me on my email address... ron.w.martin@earthlink.net with some info about you ..BTW what do you do in the "real world"?


Thanks,


rwm

As you are looking for the help, I suggest that you send me a short PM on what you need for what VIN and I will advise if I can help!!

Ron Martin

Thanks.. what is you email ?

Hey "Pluto".


We (I) may be wasting our time since I am trying to figure our how to acquire an old R230 steering wheel, cut the upper portion from the base- including the air bag and spokes with the various button accesses ... and strip it down to the female shaft (to accept the male shaft) and have a local precision machine shop fabricate my classic NARDi steering wheel onto the remaining base unit. Then locate a small electronic box with the necessary buttons to access the computer under the dash knee area to communicate with the computer.


I COMPLETELY realize I will loose the safety air bag and the phone and wheel access buttons .. having raced TDs, XK120, Lotus MK 11s, and


SIATA/Ferraris without air bags years ago ... I really could care less !


I just want to try and conceive a means of connectivity between the Nard and the computer IF it CAN BE DONE..


I hope I did not mislead you..


FYI thus far I have installed a compete P030 performance AMG package along with Black Series 19" wheels, and a Quaife LSD on a VERY low mileage (8300 miles) R230.. and intend to mount SW headers (with stripped exhaust) - no cats, (02 shims) and mid muffler.. with only a back axle TSP1 muffler along with a flashed ECU on my special SL ..




IF you think I am crazy ..I will understand....but seriously need some smarts in connecting the wheel to the computer IF it can be done..


Thanks for any help, IF you are still game !
(Never said it would be easy)

Take the wife\girlfriend or other out to dinner----you have way to much time on your hands!!

Ron Martin

Thanks.. I routinely take my wife (of 54) years out to dinner. After flying Navy planes for 18 years and 10 thousand scary hours I can multi- task...


NOW..Are you willing to advise me with the electrical connectivity for the Nardi assembly to the OBD computer ? All I need is a second opinion on creating a small "button box" located adjacent to the wheel hub that will feed the system with computer inputs when needed.

I know the Nardi automotive racing wheel and it is my estimate that what you want to do will not satisfy the registration and federal safety standards\requirements for a USA on the road vehicle----therefore I must pass. Good luck in your efforts and alert us to when you run on I4 or I75!!

Ron Martin

Thanks - and I do understand your position, BTW I had this SAME Nardi installed on three previous Porsches - 2 356s and a 911 SC... I later had it on three W107s (including a W107 026 factory "Rally" 450 SLC 5.0... So it has "passed muster" in Hawaii, Washington, and finally in Florida - without issue..


Nevertheless I respect your wishes ..


HOWEVER .. can/ will you please steer me to some R230 wheel / steering electrical schematic in order that I may "press on" with my project.


Best wishes and stay in touch,


Ron

/QUOTE]

the 2007 clk550 wheel should bolt on fine

attached is the PDF for the SCM, clockspring, and airbag on the R230.
all of your steering wheel buttons should work if connected directly to pins 9,10 and 11 (data, ground, and power .. in that order) of the N80 module.

I have to agree with Plutoe that this car RELIES to a great extent on the correct wheel (with airbag) being installed (and functioning) in order to be safe to drive. ... Maybe if you installed a 5 or 6 point harness you might be OK with the Nardi wheel and no bag .... Maybe ... (I raced in NASCAR for 10 years, so I know what it is like to crash without an airbag ... but I would NEVER want it to happen while I was only wearing a lapbelt, only one shoulder restraint, and no helmet ... my 2 cents).

Cheers,
Chris
