There is a chance that I will need to replace my engine's Injector Control Module (LH-SFI). Local dealership wants $2240 for a new one.

I've put in a message to http://www.programainc.com/ to see if they have one. Still waiting on a reply. Beckman in N. Carolina did not have one.

Do you know of any other sources for this type of part?
Is this a simple pull and replace? Can you pick one up at a junk yard? If so, how can you test them?

The vehicle has 4 control modules in the box located in the rear passenger of the engine compartment. The one I believe that may need replacing is one coded with a green triangle with part# 016-545-13-32. There is also an "LH" on this box.

The three other boxes are coded Black, Grey and Orange. The Green one has "ABS" on it so I think I can figure that one out, but does anyone know what the others are for?

Thanks!

ECU's
 

wjm,

had to 'learn' about my ECUs due to a problem and ended up posting it on a web page. All of your questions are answered there.

If you need anything else, let me know. You CAN fix those problems yourself. I did!

I have a couple nice used ones for sale. They are out of wrecked cars. What year and make is your car?

I have a 94 E420. It is Part# 016 545 13 32.

Thanks

BTW... the replacement part # may be 021 545 70 32.

Thanks

Closure
 

Since I was able to find a computer which was the exact same version as the one I had in my car for a relatively cheap price, I though I would go that route first.

I snapped the old one out and put the new one in and then went to my mechanic to have all of the computers cleared/reset.

It seems to have solved my problem (at least temporarily). Normally the check engine light would come in the following day (with light driving). It's been off for 4 days now.

Should I have the same problem in the future, I'll replace it with a newer software revision as suggested by Mercedes Benz. Heck, I'll keep my eyes out for this newer computer to see if I can get one just as cheap.
