Found a secret door!!! (Shhhhh....)
1 Attachment(s)
While working under the dash on the passenger side, pulling a new wire for an auxiliary power outlet (aka lighter socket) -- but that's another story -- I discovered a Secret Door in the passenger's kick panel. For all the times I've lain on the floor, wiring speakers and such, I never noticed this thing before. :o
As the picture shows, behind 'Door Number One' is a black box, some kind of electronic thing, I suppose, and a round thing that says "EGR" on it. Well, we all know what EGR means but what are these two things? Are they unique to the 1985 model W123 diesels? Jeremy |
Looks like the idle adjuster on the later cars. Can't be though, afaik the 617 never had electronic idle control.
|
In the 123 series that location and item is 85 only. Remember to remember you have it as I believe the tach feeds through it as well. Might not hurt to examine the archives for the other functions or if you get a chance to look at 1985 service information.
|
Yep, no such secret panel on the W126...not on mine anyways.
|
That is the egr computer, but it also operates the tach. The pins on mine were green and badly corroded. Something else behind it, I don't remember what though.....

He's got a CA model 85 300D. Crazy emissions stuff on that car.

Mine doesn't have it (83 Federal)
What does the egr do? |
Quote:
*Decreases engine power / speed *Obliterates MPG *More not-so-great stuff What it's supposed to do: *Decrease emissions What everybody does: *Stick a BB in the EGR line to stop it from being used. |
Besides the tachometer being dependant on the EGR electrics, isn't the speed sensor for the AC compressor also dependant on the EGR and that if there is a problem, the ACC will not function?
|
gasp! I thought that those bbs were in your exhaust all the time and they tend to clog up your lines :confused: BTW i work at napa and if someone comes in asking for a "test pipe" or "some pipe to replace my cat with" or "a drain plug to plug my egr" I can't sell it to them. If you don't tell me what it is for, i can sell it. BS gov :fork_off:
|
i need that door, mine was missing.
|
I have the exact same car as you, even to the interior color.
I don't seem to have that EGR device. I'll have to doublecheck. A P.O. used it for installing a satellite radio tuner. |
