Can you see what it is yet

[spartan]

Still not got the 280e going just need to know what this is dont want to sound thick but I cannot find any reference anywhere for it the numbers on it are 0265101006 and 3434719 says bosch, stab in the dark mixture control ?

Sorry if the pic dont work.Kev

I am guessing, its off a W123. I haven't physically seen the part, but the size of the connector suggests its an ECU. I would suggest, tracing the wiring from where the plug is. If it splits off and some bits go to throttle body, sensors, etc then its the ECU.

Once its all fitted onto the car, what are the symptoms of your problem?

Just check tis previous thread Old girl Mercedes 280E start stop. Its being a very slow process in repair the engine type does not seem to fit in with what it is supposed to be.

 

[paulcallender]

Are you thinking that there is a non-standard Mercedes engine in your car? I think http://www.mbz.org/cars/motor/ has a resource where you can look up the first 6 digits of the engine number, as fitted to each model. For example you could look up the correct 2.8litre motor for a W123, to see if yours is the correct type of motor.

ecu

looks very like bosch ECU. Was it located on engine compartment bulkhead? location might help identification!!

It was in the passenger footwell behind a pull off cover. Thought the ecu was on the side of the engine bay passenger side near the front. The engine number on the v5 matches how it should be but I cant find the engine number anywhere on the engine no dont worry deff not a ringer. Just very strange.

Mystery solved?

Obscure German Recon Site lists this as ABS UNIT For DB124/ DB 126 Models Sorry No More Info Than This

 

[spartan]

Really scratching my head now, ABS will have to have a rethink I really thought it was to do with mixture control no way to follow the wires to see where they go. I still love mercs.

 

[paulcallender]

Why can't you follow the wires?

The location you describe, suggests ECU.

 

[spartan]

Because they go into a wiring loom through the bulkhead and out under the battery where a large wiring loom comes out. Have tried .

 

[spartan]

After hours of trawling the web I found this 2 numbers out on the last digits but its from a Jag says ABS ECU

Sorry to be such a pain but could this still be a ECU and not a ABS.

This is where the unit came from side of passenger footwell.

This is what I thought was the ECU

And finaly the engine.
Apologise to all for taking up so much of this thread but as you preberly guessed I am running out of ideas.
Any help really appreciated Kev

 

[paulcallender]

The engine is definitely a 110 motor.

What you thought was the ECU, is in fact an electronic ignition module.

 

[spartan]

thank you so much now that puts a different light on things. Forgot about electronis ignition to much time spent working on old fords, Dur
Kev :smile:

 

[grober]

Sorry Ive been away. Pauls reply is confusing IMHO. sorry Paul. I think he means the unit on you inner wing PICTURE is the ignition module-thats correct. The original unit in the passanger footwell is the ABS UNIT !!

 

[grober]

Have you tried looking under the glove box compartment older mercs used to hide their engine ECUs there?

 

[spartan]

Thanks for that grober will have another look. went out today and bought another 1983 280e can swap bits around to try and find the fault now. well thats what I told her who must be obeyed lol.

[paulcallender]

Just out of interest, how much did your second 280E cost? I am assuming its a non-MoT'd spares car?

 

[spartan]

MOT until December taxed till July runs really nice £470.00 not a bad price nice and clean
