W124 code READER

Does anyone have a good code read for w124. Have anyone heard of a MERCEDES OBD1 CODE READER they have one on Ebay. I want to know a little bit about it before buying one.

It;s a high priced version of this.

http://www.ebay.com.au/itm/Mercedes-...item4cf9d50f32

All it is is a blink code reader with set of banana plugs !

$30 versus $89.95 for the one you showed.

Same functionality.

OR

$10 worth of parts from Radio Shack to make your own.

Don't know what that first number is but the VIN (the WDB) number doesn't show up n decode. Are you sure about those numbers ?
Post a picture of the data plate.

Sorry I was away on a seminar.
There was a mix up. VIN is WDB1240211B095611; Eng. No. 10296310039552E90.
Again, which is the best scanner for this vehicle?

Thanks for reply.

Thats better early 200E with M102 engine.
Same as in post #4 above.
Only code reader is one that shows number of flashes which is errors.
Nothing fancy about them ! NEar fuse box you should see black/brown thing with numbered holes - you have either 8 or 16 I would think.
Here is where you get error codes.

Thanks Stormtigers for your reply!

The car performs fine, I love it. My curiosity was just in case I needed to scan it.

There seems to be some confusion as to what type of scanner to use on what model of W124----It all depends on the type of diagnostic connector your car has. There are 8,9,16 and 38 pin connectors.

The device advertised is actually an "on off ratio meter" that only works with the 1980-1994 9 pin diagnostic pin MB vehicles. With the 8,16 and 38 pin type you need the MB HHT(or equal) or if the 38 pin car also has and OBD port you can use the every day scanners.

It is confusing therefore be very knowledgeable about you car before you buy any diagnostic equipment

Plutoe are you referring to the original OP mention of an OBD1 reader or the cheaper flash reader ? They are both the same thing despite it being called an OBD1 both use set of banan plugs. The original one is really just an overpriced "glossy" of the one I mentioned.

You are correct ----both, are simply "on off ratio meters" used on the older 9 pin diagnostic connectors

My understanding is that the '95 model does not require a code reader.

Had the check engine light on awhile ago and stopped by a mechanic that worked on European cars and he read the blinks and looked up the "code".

What is the secret to all this? I have seen the code documentation but not exactly sure how to begin and read the leds to determine the code?

Thanks!

Well you are correct and almost correct----to really determine what diagnostic tool to use-------please tell me how many sockets are in your diagnostic connector or provide the VIN and I will then find out!!

I thought I could get closer than I did. You either have the 16 pin rectangular type(passenger side near firewall) or the 38 pin circular type(drivers side under fuse flap).

In either case and since 1994 the pulse counter type was discontinued and the use of the MB HHT(also incorporated in the current DAS Xentry diagnostic software) is to be used, but the 16 pin type still had the two small buttons to retrieve the faults.--------I have no idea if this helps or what all I know if you know someone with DAS Xentry they can diagnose your car!!

Passenger side rectangular type is what I have. Any procedure overview on how to retrieve the fault code?

Thanks!

Based on your VIN and what I have read your 104.992-----the faults can only be read out with the MB HHT and DAS Xentry using the three plug type(red, white and yellow) adapter---The pulse reader is not applicable. Therefore there are loads of indies who have the DAS Xentry diagnostic software that will be able to read and and clear all motor, chassis and body codes.

Okay, but this german mechanic did not have any other tool than his eyes and counted the blinks I suppose.

Thanks for the info!

It has been my experience that all pre-OBD W124 cars (1995 and earlier non-california) can be read using the pulse counter device shown at the beginning of this thread. All the three lead DAS adapter does is send the pulse counter the the DAS multiplexer which in turn sends it to the computer. In this mode, all the DAS software does is count the pulses, then lookup the fault to display on the computer screen. A list of fault codes can be found online for these cars, so all that is really needed is the simple LED/push button device. Starting with OBDII you get the 38 pin round connector and DAS / Xentry is required.

Hages, you don't need a pulse counter, its built into your diagnostic connector---see button 2 and lamp 4---thats how your mechanic retrieves the faults----keep that guy on your Christmas list.

Thanks Plutoe.

Can you explain how to perform the code reading? Should the ignition be on or on ACC and I push once on the #2 button and the #4 led blinks and I count the blinks?

Rocket science to me....

Please do a search yourself----the web is loaded with info on "MB W124 blink codes"

I am lazy----I just plug in my DAS Xentry and wait for the answer!!

Okay, I do have the 24 page PDF doc (DTC_W124_M104). Just wondering if there is something unique for the '95 California emission model.... guess not, no worries.

Thanks for your help!!

Check out this YouTube Video:

It appears he is seeing two codes: 3 and 10

Does that correspond to(?):
Code 03: Lamdba control inoperative
Code 10: Voltage at hot wire mass airflow sensor too low/high

Thanks "experts"!!
