Re. Year 2000 430CLK Cabriolet.

I need a bit of info re. the breakout box, but first, Question #1:
when I have the ingition key in position 1 the module in my interface won't connect. When I have the ignition key in postion 2, the module connects, but I hear some component in the engine compartment running. It's a buzz. It makes the same sound as my bike when the fuel pump is presuring up the system. I don't know what it is, but it seems under stress, and that running it without the engine running, might cause it some damage. Any ideas on this ?

Now, the real question. I have read a load of postings on these forums re. Carsoft 74 and interfaces, etc., and I would like to be sure that I understand.

I have a MB interface which I purchased on the net. I loaded Carsoft 7.4 onto my notebook and connected the interface to it, then to the OBD2 jack under my dash. I tried diagnostic scans on all of he systems, both as a complete scan, and individually. The only diagnostic I could get was the "ME" one.

My interface came with an additional cable that seems to replace the cable between the interface and the OBD2 connector on the car, with a set of banana clips.

Question #2:
Does this mean that if I buy a Break Out Box, then I will be able to run diagostics individually, and with success.

Here is a link to the components I am talking about.

Question #1........... I think you will find the sound you are worrying about is the throttle body stepper motor that controls to butterfly position......no concern

Of more concern is the time you leave it set in position 2....ignition on......try to keep this to a minimum.........

ME.......good start...............you should also be able to clear codes and get live data and even do an ME reset.......worth the price you paid alone....... :D

As previously advised you may be able to access some other MB systems if you use a breakout box........but nowhere as extensive as with a 38pin connector.................

This link may help with the OBD2 connector

Breakout box available from China for ~ $US40 + del

im not super familiar with diagnostics on MY 2000 but i believe that you need to be on the diagnostic CAN lines to do the more indepth diagnostics. the 'ME' diagnostics are usually only on iso9141 (K-line).

Carsoft 7.4 is not CAN BUS compatilble...........only accesses K-lines.........so as Rob posted above, this is why you might not be able to access more indepth diagnostics........

Still worth a try...............find a way to connect to say pin 11 for a start.......use the lead with the banana plugs.........red and black to battery, yellow to probe pins....................then do an EGS Digital test for Transmission.....if it says module not installed, try other pins.......be careful not to short any pins and turn ignition off before connecting & disconnecting...................please post back what you find...........

If you check your OBD2 lead with an Ohm Meter, you will probably find only 3 pins connected.....2 for 12V power and one to K-line for ME................

With regard to your codes..............if it's a long time since any diagnostics were run on your car, then it's often worth making a note of them and then clearing them.........no date stamp on codes, so if they come back then you know they are current...............

I saved the file, and then cleared the errors. Will see what happens. I would bet the fuel tank pressure error is from the time I have left the gas cap off for about two days, about 6 weeks ago. I am hopeful that it won't come back.

I bought a brake light switch about a week ago, but still haven't had time to install it. That error has been reocurring as the switch has been failing.
Here's a link:

I'm not going to risk shorting out something, and frying my computer or my car. Need a break out box.

I have been looking on the net for a break out box that is not insanely overpriced, ie. $100+. No luck so far. These are simple devices, 16 banana receptacles at about $16, a small project box at about $2, and a cable with OBD2 Plug at about $20. The net has then for about $150. That's crazy. I'm going to look around for the components and make one.

Question, are these boxes hollow (straight wired), or do they have resistors, etc ? Anyone looked inside of theirs ?

Here's one....under $US40 + del , but ask for price......I got my I/F & Multiplexer Selector 38 pin plug from them......paid by PayPal and got it in Australia in under a week :D

Vag-com,TachoPro,KWP2000,BMW Scanner,BMW Carsoft,MB Carsoft,ELM323,Code Reader,Can-bus

May also be available on eBay........OBD Factory might not be interested in such a small purchase............

Would be easy to make up yourself.....no resistors....direct connections.....

Good Luck

Thanks for the info. I have seen this BOB, or one like it. Has about a 12 inch cable, that might not even reach out from under the dash.

Also, previously emailed this vendor a couple of times re. the multiplexer, and never heard from them.

Tonight I emailed them again re. prices, shipping, and form of payment for ordering the multiplexer, and/or the breakout box. Maybe I'll get a response this time.

Well, received my email back, "undeliverable". I don't know how those chinamen do any business. Maybe it's the commie way of doing things.

The Parts cost for building one, $30.29

Appearing to be an Auto Parts business requesting a sample seems to get a better response :rolleyes:

I still have a strong feeling that you could be wasting your money on the 'Blue Box' automatic Multiplexer in the post above, unless you have the 38 pin connector...............

The Multiplexer just does electronic switching to select the pin...........but is no better at reading the data if it is not a K-line...........also not CAN BUS compatible

I would go with the breakout box kit..........or even just the plug & wire for a quick test to see if any compatible data is available before making the fully assembled unit.....should be easy to access pins with lead chart and an alligator clip on the yellow banana plug..............

Please be sure to post back your findings here and on the SLK Carsoft thread

Link to SLK Forum Carsoft thread for those that want some extra info...........but be advised that at this stage I would only recommed this system for those with the 38 pin socket (Europe / Asia / Australia etc.......not USA in most cases)

Found the 38 pin socket under the hood, under a round cover, near the passenger's side hinge. So, the 2000 CLK430 has both the 38 pin, and the OBD2 diagnostic interface. See link below.

At $400+ for a m-plexer, and $150 for a BOB, the "build you own BOB" seems like the way to go. Ordered the OBD2 open end cable this weekend, will order the banana females and project box later, and will post the results of my efforts.

Do you think the 38 pin improves the odds of a multiplexer helping me ?

What would be the maximum length of cable for a BOB ?
Would a 10 Ft. cable be too long, ie. lose data, not connect, etc. ?

If anyone knows of a good source for a $200 m-plexer, then let me know.

If anyone knows a good sorce for a $50 or thereabouts BOB, then let me know.

Link to both interfaces:

Hi Pancho,
There are no need for the BOB unless you you want to do both 38 pin and OBD2. The m-plexer will do all.

I don't have a m-plexer, and don't believe I'll be getting one.

What do you mean no need for the BOB ?

Sorry it did not come out to clear. What I meant is you don't need the BOB if you where going to buy the m-plexer.

Have found a Mercedes Multiplexer comptible with my CLK (W208) for a good price--less than $300.

Important Questions:
1. Do I still need my MB Interface.
2. Do I need both a Multiplexer (which I don't have), and the MB Interface (which I already have.) ?
3. Will the Multiplexer do all that the MB I/F does ?

I know that Multiplexers have automated K line switching, but I don't know whether I still need the MB interface I have.

Let me know, because I can still return the MB I/F for my $ back, and buy this multiplexer.

You will need the cable going from the m-plexer to the 38 pin socket, and of course the serial from the laptop to the m-plexer. You will not need you present MB interface, as this is in fact only a "dumb" m-plexer. You have to make sure the m-plexer is compatible with Carsoft 7.4.

Here is a little list of what you can do with the Carsoft 7.4 and a compatible multiplexer (this list is from the one I've got, which is the blue one you have mentioned. (I paid approx. 280$ for that) :

As macclk posted......you will not need the I/F if you have the Multiplexer........

i.e. Multiplexer = MB Interface + Automatic K-line switching

If you like the idea of an automatic multiplexer then suggest you copy any supplied software before returning 'Plain' I/F......Carsoft 7.4 should work for both and software may not be supplied with the 'Blue Box' Multiplexer on eBay

The Multiplexer in macclk's post is different to the 'Blue box' OBD Factory one.............but is probably similar electronically...........

Both will come with required cables............

I have had a price of $US198 + del from OBD Factory.........so $US300 is a reasonable retail price if there is some backup and you don't feel inclined to take a risk with delivery from China............

I personally think that $US300 is very good value for its capabilties :thumbsup:
(but you might not find everything shown in macclk's list above works with these clones)

As an exta note.........a fully automatic scan with a mutiplexer can take 45 minutes and put quite a strain on your battery (looks through all systems sequentially to see if installed).......I can do a manual scan of all the systems that I know are on my SLK with my Multiplexer Selector Plug (electronic break out box) in less than half that time......so there is not a great benefit in having a multiplexer unless you are a Tech working on several different MB's - IMHOP (more electronics to go wrong)
