i just found out that I need a new idle control relay. This is fedl. spec early 85 2.2

The one installed appears to be from a 240 as its number is 003 545 2282

Does any.one know the correct part number? My car was delivered to the original owner in dec of 84. Maybe the 2232 is correct but lots of things happen under the hood in 30 years... There's nos available but they are marked for 5 cyl which gives me pause.

I can't get the Russian epc to work for me today

Is this information any use?

Don't leave that there - I'll take it to bits!

Thanks but no. The relay I seek a pn for is located behind the battery and behind the klima relay. It seems to be called "diesel idle control module". Cover marked ELR Diesel 4zyl

There are two on eBay with pn 003 545 2232 one says fits 190d and other says doesn't fit 190d. I pulled the defective from my early 190d with this part number.

Furthermore: will a 5 cyl idle control module work in a four cyl?

OK different picture =>

I really can not help with this other than posting up more links to pictures - I don't know what the difference is between 4 or 5 cylinder relays (if anything).

You need to get some decent advice from someone with access to the "grown up" EPC and ideally a friendly mechanic at the dealership. Otherwise there is often talk of a classic Mercedes centre in California that might be able to help.

Stretch: That diagram shows another number but I found this entry on DD
WTB 190D 2.2 fuel pump relay

The poster wanted to buy the same part number and had the same model, meaning two of us found that part number under the hood. I'm running with it.

My rocket scientist had this to say:

"The late 70's CMOS chips they use are highly susceptible to fatal damage from static discharge - ESD exposure from poor handling practices. Just placing one of these into/out of the socket or rubbing the contacts while un-grounded when removed will instantly destroy the unit".....


I'm now trying to find out how to avoid this... I wonder if in placing theses behind the battery was a german way of insuring that you had the battery disconnected, if so, another example of designing for the real world.

I'll ask someone who knows more about these things to have a look at this thread

Thanks for that. The electronics in these aging beauties is a weak link. Although mine is more or less drive able with both the klima and the elr pulled out completely. But I want a/c, cruise and kickdown, and they all seem to be tangled together In these two relays.

Feel free to chime in-- I personally don't have the big picture electronically. This generation is sort of half analog/vacuum and half electronic, so lots of chance for confusion. I wonder-- do you have the emissions layer over there in Netherlands that I'm staring at?

The correct p/n is A 003 545 22 32.



Salut!

That's the one I ordered-- the picture looks familiar!

Marked as "5 Zyl." is for a 5-cyl. only.
And here is a wrong number for the 2.2 D.

70's CMOS chips = 4000 series parts. Verrrrry cheep out there now.

Yes but the OP has a 4 cylinder engine doesn't he? So how come the right / correct part is marked as 5 cyl?

(Or have I gone and gotten the wrong end of the stick?)

Sorry. Yes, you have.
