W124 code READER
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.

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.
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
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!
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!

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

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....
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"!!

Get creative and build your own code reader! About $12 worth of parts and 1 hour of time. Its nothing more than 3 wires soldered to a push switch and an LED stuffed into a plastic container. And the PDF code file is available for free on the net. Keep it simple!

My family and I will be in Boston the 2nd or 3rd week of March (spring break). Never been to New Hampsire and thought it would be a nice drive. I'd like to check out your welder.
