Hello,
Searching mb and benz forum for Airmatic realy came up with too many different part#. Which part# is the correct one? some said it is green color. now, I am getting so confused.
Here the list:
002 542 72 19
002 542 26 19
002 542 13 19
I ordered 1 from rm european web site. They sent me the
Hella 4RA 007 791 011
I called to them. They said it is the same as the 002 542 13 19

Could someone confirm this, please?

Thanks,

Hello Konistiger,
I have to ask you another question about the relay.
The reason is today I called to Mercerdes Dealer to buy Airmatic relay. It is ParkPlace Motorcars of Dallas, talked to Randy at part department. When I asked him about part#, he told me it is 002 542 72 19 and it is $65 and it is on back order.
I told him about 002 452 23 19, he says, "I don't know, if you want 002 452 23 19, it is $17".
Now, I am even confuser. what is 002 542 72 19 for? on the relay list on your post. It says, "Pneumatic suspension k76" Am I supposed to change it after changing out Air compressor? What is the location for it?
The reason I looking for the relay because I just changed out the air compressor.

Also, another confused situation for me is the orginal relay in slot S in the SAM in my car is Hella relay, part# 002 542 13 19 with Mercedes logo on it, and made in Spain.

Many thanks in advance, Konistiger.

I would base my purchase on part # found in vehicle, 0025427219 replaces original 0025421319 installed at production. BTW, what leads you to believe it is the relay and not fuse f74 (40A) @ front prefuse panel?

Henry.d

I am not the first owner. That is the reason why I don't trust the original relay part# as the people often play with it.

I just changed the compressor and want to change the relay and fuse as recommendations.
The original compressor stopped working b/c the air hose was broken and the compressor just sucked all the dust in bypassing the air filter.
Germany car makers are famous about their plastic and rubber parts.
On your relay list, It has both
002 542 23 19 Airmatic slot S and
002 542 13 19 Pneumatic suspension K67, replace by 002 542 72 19
Why is that?
Is Airmatic = Pneumatic suspension?
Should I go with 002 542 72 19 or 002 542 23 19 or 002 542 13 19?

On the forum, most people talking about the after-market Hella 002 542 13 19, made in china.

Does the relay part# depend on car VIN# or year make or model#?

Thanks,
HD

I agree you should replace associated relay when replacing malfunctioning compressor. Spoke with several parts managers and all concur 0025427219 is correct for your 211.070 unknown why both part #s reference Airmatic - your call OEM (parts.com $31.62 or getmercedesparts.com $34.50) or aftermarket (autohausaz.com $14.17) my recommendation - OEM.

Hey henry what part number did you used cause i was confused too. i have 2003 E320 and i called mercedes and gave them my vin# and the part number they gave me is 002 542 7619 which you do even have listed. also the cost was $10 from them. The website i order is from is genuinemercedesparts.com

konigstiger

EPC shows 0025427619 as starter relay for G400CDI, not listed on e320 relay list correct OEM part for your e320 is 0025427219. See post 5 to identify location.

konigstiger,

Can you post the Prtlist and SAM Relay for E350 2006 base model? I have an Air Injection Pump bad and I need to replace Relay and fuse as well.

Thanks

Konigstiger,


My SAM box R-relay doesnt show the p/n. Please see the attached picture. Is the part (with the red arrow) right?

konigstiger

Yes, this is R relay part # 0025421319 for e320 see post 9.

Hi all. I know this question has been beaten to death, but i'm still confused. For my '05 E500 4matic, autohauzAZ only has 002 542 26 19 (Hella OEM), which is a 4 prong "multipurpose" relay. It is the only one they sell and looks exactly like the 002 542 13 19 that is the "correct" part number. http://www.autohausaz.com/search/pro...nation%20Relay

I ordered it but am now hesitant to try it. Does anyone know if it will work in place of the other part number given that it looks the same and is "multipurpose"?

Plutoe

You want to be extremely careful----the relays are not interchangeable and depending on your model car that relay performs a different function than used on another model-----If you provide you VIN EPC will tell you which one is for your car

Thanks Plutoe. I figured as much. Been having getting some errors subscribing to EPC using the link above but will try yet again.
