W211 Fuses, Relays, SAM Modules chart

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

Oh man this would have helped when troubleshooting my HID power issue when I checked all of the fuses individually and reseated them, not a huge job just a pain in the a** if you it's your first time messing with electrical on the car. Does this apply to facelift W211s as well has anything changed?

Problem with false warning indicator

I have a 2005 E350. The warning system indicates 'check low coolant level'. The coolant level is fine. There is no loss of coolant. The engine temperature stays normal. I have replaced the sensor under the header tank to no avail. The agents say the front SAM unit must be replaced at great cost. Is there a relay or some other component that has failed and could be causing this? Originally the warning came on intermittently but is now on permanently.

The front SAM on the mbz does go out (if you get moisture inside), they all do. Depending on which 'SAM' you have 100-300 USED online. I might have one or 2, PM last 8.

Thanks for your response. I am in South Africa and this is a right hand drive car. Will yours be suitable and, if so, what would the price be?

Exclamation E211 fuse - trunk not closing or lights

Lights in trunk and auto trunk shut don't work... Checked wiring and the only thing I think it could be is a fuse... I can still open from driver door and from outside trunk just a pain to have to go back in the car to shut the f'in trunk. Any ideas of a fuse that could be checked???

sorry if I missed it, but is there a fuse for the interior light for the trunk, or one for the electronic door handle? Those are the two items thtat are currently not functioning properly for me. THanks

W211 E55 AMG and non-AMG fuse and relay chart

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.

Hey Gents... Command issue... Hoping for pointers.

Command had been working mostly... It would intermittently take a break after operating for a while and then power up later. This went from an hour of no tunes to 2-3 days of no command. Then no Command.

Fuses are all good.

Edit: power through the fuse... Even using a test light with an incandescent bulb so it will pull some power didn't sniff out the fuse that had high resistance on the blade of the fuse sending power to Command. Testing it again with low ambient light... What are these little arcs as I probe the fuse with the test light? Replace the fuse and problem solved.

Ahh the joys of intermittent electronic issues.

Still trying to find source of #4 cutting out with heavy load... Key off and runs again.

Front SAM (engine compartment) 54a FYI for constant power you can move fuse from 54a to 54b.
