Since I also saw the post referenced and this post while troubleshooting my E55, here is some additional information for this resurrected-from-the-dead thread. Some of this info is from recent threads, I don't have the details to credit the posters but my thanks to those who posted the information they had.
Front SAM:
Position kR in the first document is the air pump (non-AMG) or oil cooler fan relay (E55 AMG model).
Rear SAM:
Position kA in the first document is fuel pump relay (non-AMG) or heat exchanger coolant pump relay (E55 AMG).
E55 AMG only:
Fuel pump relay and fuse is located on opposite side of trunk from the rear SAM; only accessible by removing the trunk panel; no access port.
Air pump relay and fuse is located on opposite side of trunk from the rear SAM; only accessible by removing the trunk panel; no access port.
Early W211 E55's (build date prior to March 2005?) may have air pump relay located in engine compartment next to auxiliary battery. Any info here is appreciated.
Photos attached show location of build date after March 2005 E55 AMG air pump and fuel pump relay locations and what a bad fuel pump relay looks like.

Maaaannnn I was going crazy trying to figure out how come my fuel pump was still working when i took out the fuse and relay in my 05 E55 !!! I was about to change my sam module in the trunk thinking I had a short or something..LoL .. YOU ARE A LIFE SAVER !!!

Thank you so much for that. Mine is exactly the same. The chart tells me about the fuses but has no information about the relays. My airmatic has quit and I am trying to find the relay for the compressor. I thought I had found it under the hood, correct part number but when I jumped it the cooling fan came on!

Many thanks. Unfortunately mine doesn't look quite like that. Mine is a Right hand drive so the fuse box is in front of the driver on the right hand side and the relay layout is different. I will revisit it in the morning. New to this forum but will try and post a photo of it tomorrow. Thanks again!

Fuse chart from inside by the driver door, it doesn't give any info on relays!
The Relay and Fuse box under the hood in front of the driver. No info under the lid, no chart and relays are unmarked so it is guesswork. Thought I had found the airmatic relay, correct part number, but when I jumped it turned out to be the cooling fan. Amazing lack of information provided with the car.

The SAM in your photo looks like it is reversed from the drawing I posted above minus relays M and R. Your photo shows what appears to be two relays behind your SAM. Any additional details on your W211? Year? Engine? As an example, the E55 came with multiple versions of the wiring harness so knowing the year is vital to finding some of the relays' locations.

Under hood in front of driver (RHD car) looking back towards driver. Two relays lurking at the back but difficult to reach or photo. Need to know where to find the airmatic compressor relay??
Relays marked up, photo taken from right-hand side of car (drivers side UK car) Jumped relay I hoping it was the compressor (correct part number 40A) but the cooling fan spun.
Hi thanks for your reply. I have marked up the relays and taken another photo. Yes there are two relays lurking at the back which I cannot easily reach or identify. This is a Right Hand Drive UK car. Registered 2005 E320 CDI with the IL6 3.2 litre diesel engine.

Agree, the direction of travel is 180 degrees out. I will attempt to get the square white relay out from the back. It is very inaccessible. I would love to fix this myself.
Thank you for your help, much appreciated.

Thanks for your help. Latest, I did locate the airmatic compressor relay at the back under the hood. I removed it and it was the first time I got a message on the dash saying attend workshop with an icon of a car body with an up arrow under it. I have replaced the relay with a new one but still no action. I jumped the relay and the compressor runs so that tells me that the car is not calling for air for some reason, I have reached the limits of my investigative powers so I am taking it to a specialist on Wednesday of next week. Frustrating to have it sitting useless outside the house for another week. On the plus side I have really enjoying driving my partner's Jaguar, it's so agile, responsive, quick and quiet that I am in no hurry to get back into the Merc, perhaps just as well.....

teleaid fuse location
Found this while perusing electrical schematics for the W211 and W219 which are essentially the same car with different sheet metal and interiors.
Teleaid fuses:
Schematics for a CLS500/550 and W211 E55 indicate fuses 50 (5A) and 55 (7.5A) in the driver's side front SAM power the emergency call system controller which is listed as module N123/4.
F55 has notes "for fixed installation telephone".
F50 has notes for "CTEL separation point" (unless you have a Japanese-spec car in which case it is a "VICS power supply separation point").

Hi Simonkd
Im in the same boat, been scratching my head over location of airmatic relay confused by the various post and discrepencies in models/info etc. Are you able to post a photo of where your relay is located.
Cheers

Hi Guys,
I have a 2008 e550 and have the P0410 error code. When i looked for the fuses, i found the "kM 002-542-13-19 Relay SEQ [ASG] pump control relay" missing.
Any idea if this is needed and could be the reason for the code. I do have F61, F62 (look good) and Relay R

2006 W211 CDI
Hello All, I am having a front SAM issue with relay I on my 2006 W211 CDI. I have12v on terminal 30 and terminal 85 on the relay. From what I can tell when you turn on the ignition terminal 86 should go to ground to activate the relay. Mine is not activating the ground to actuate the relay. I can stick a jumper between terminal 30 and 87 to start the car and it appears to run fine. Any ideas why I am not seeing ground on terminal 86? I found this video on You Tube with the exact same problem I am having. This is not my video.

W211 320i CDI Avantgarde 2003 OM648
@mikewessel
Thank you. I seem to have exactly the same problem on my W211 320i CDI 2003 as in the video we both found on YouTube. See also my thread : https://mbworld.org/forums/e-class-w...ml#post8338637. As in that thread I would like to find that brown/yellow wire in the video we found and test the jump to ground on the car mass when the problem happens (no crank, no start, when engine warm, ESP error message and fan starts). Maye you can feed my thread too, I am trying to connect the two threads. I am sorry I did not test ground on the terminal 86 (where can I find the schematic of the relay with the terminal numbering?)

W211 320cdi
After hunting all over for a complete chart of all of the Fuse, Relay, and SAM module details including amperage and locations on my 2005 E55 AMG (W211), and not finding a nice concise chart, I wrote one. I hope you enjoy. (If you have corrections and/or additions, please PM me so I can update the file. Thanks.)
This link points to a two page PDF file which prints nicely for those who want to fold it up and keep it in the vehicle for future reference: http://kropf.net/w211/W211fuses.pdf
For any without a PDF reader, images of the PDF file follow:
Jun 18 2019: I updated the .pdf file to include most relay numbers, and a few other edits.

Clicking on the URL's you copied into your message results in success for me. I can bring up the PDF. Maybe try clearing your web browser cache and try again.

Quite helpful. Trying to get to Fuse F87. I have a 3rd row seat with carpet - it appears just out of sight / hidden. There is indeed a fuse box back there? No carpet tricks?
