Such things don't get repaired because of fault codes, they get repaired because the car won't run. How well does the car run? The engine actuator / aka throttle body can be rebuilt by Beckman Technologies in NC at 800-742-1021. It could also be just a bad harness for the engine actuator. If it was me I would not go back anywhere that had to cajones to give such an estimate. You should get a second opinion from an honest independent shop, or if the car is operating just watch the fault codes yourself.

Here's a link to a guy with a 600SEL with a V12 who has done some of his own rewiring:

The idea's the same, you just have fewer cylinders and more room.

You can get a reman 000-141-49-25-R from Beckmann technologies 800-742-1021. Less than a GRAND..the computers hardly ever go bad & Beckmann can supply a reman unit for that as well.

That's a pretty impressive list of codes, but do you suppose this could be the engine wiring harness?

Thanks to all for your replies.

Runs ok, but I'm only doing local in event "limp mode" activates.

So it the "wiring" not the modules. My mother in law used to build circuit boards for Allen Organ. She likes me, but this is gonna take a lot of chocolates

Good to know if I can't bribe mother in law.

Jealous are you?

I think mine was replaced, but you have an excellent point. I'll have a "professional" look at it.

Keep those cards and letters commin'

PS SPRING iIS HERE!!!

You don't really need to have a "professional" look at the wiring harness. Find a part number on it and post it here, someone will know whether it is the updated one or not.

Just FYI

Good Luck!

Eh, I've got two codes on pin 8 (4 & 13), but pin 14 is looking clean so far. Think I need a MAF.

My codes only add up to 17, yours to 24. You win. How's that for diagnostics?

I have a good friend who works for a dealer in a major metro area. His honest opinion is that none of the techs there know how to work on aything more than about 5 years old. Having come from my shop as one of the techs who only worked on "newer" cars he was surprised to find that he was the only one who actually knew how to fix '95 and older models.
The moral is that your car is becoming obsolete in the terms of technician knowledge. The classes that taught techs how to work on those cars was 10 years ago. How many dealer techs have 10 years of tenure?
I ask this because there are several different problems that can cause your code 2. The least likely of which is the actual module. A tech that isn't familiar with the system and how to daignose it will end up costing you a fortune. Your best bet would not be the dealer unless they have an older tech driving the same car for a daily. I'd reccommend that you find a good independant shop capable of performing a thorough diagnosis. Fixing the problem and fixing it right the first time is crucial in minimizing the cost of repairs which, as I'm sure you're realizing, can skyrocket if it takes more than one $tab to "kill" the problem.
