Dead Indicators, inacurate fuel guage
My W164 gave me a battery warning for the last couple of weeks but it always started with no problem, even after not used for a week.
This morning the turn signals is dead, the emergency flashers does work, after driving for about 20kms the fuel warning came on stating a range of 30kms, I knew the tank was almost full. I stopped at a filling station and it only took 20 liters of diesel to full. After filling it to the brim, the guage came up to the half way mark.
When I arrived at my destination I wanted to check the fuses but the boot would not open, not from the key, the drivers door or the hatch?
Back home I connected a good charger and charged the battery, it made no difference, I disconnected the battery for a couple of minutes, that made no difference either.
I checked fuses 11, 40 & 48 which seem to be relevant, they’re all fine.
I scanned it and found the following codes
9345 Fault in CAN communication with control unit EIS
C335 Control module N22 (aac) is not sending any data
9115 Control module AAC is not sending any data
Please help?

What color was the battery warning, RED or WHITE?
When you say the turn signals do not work, does that mean that there is no indication on the cluster, or on the rear, or on the front or everything does not work?
Code C335 appears to be from the rear SAM.
What modules were these codes stored in?
Does your A/C work properly?
Have you experienced any water leak in the spare tire area??

Thanks for your reply.
It was white, I replaced the auxiliary battery today, on my dealership’s advice, the battery warning is gone now. No other change.
Turn signals totaly dead, nothing on cluster or outside, no clicking sound nothing. Even my obdII scanner show indicator off whether I turn it on or off.
hazard flashers work fine.
I’ll do another scan to check which module its from.
Aircon work perfect, we curently have a heatwave here, 35plus degree C
Yes I had a lot of water in the sparewheel area about four months ago, had to replace the tailgate pump and ECU.
The tailgate lock has been noisy, a crrrrr sound since I closed the door on an electrical cable about a year ago, this might thus not be connected to the indicators and fuel guage problem.

Have you replaced both Tail Lamp seals? They must be attached to the body opening, not to the lamps.
By ECU, do you mean the Rear-end Door Closing Module?
All of the problems you are having are controlled by the rear SAM.

���� The 20 liter of water came from inside the boot so I did not replace any seals.
yes I replaced the arrowed unit and the hydraulic pump.
I just read that the rear sam also control keyless entry, I have experienced intermittent problems with it over the last two weeks, so it seem very likely thats the culprit.
Its going to be fun trying to get to it without opening the tailgate!

Thanks you were correct, I removed and opened the Rear SAM, is has clear signs of water damage.
I'm currently seeking a replacement unit.

Don't forget about replacing the tail lamp seals.
Remove the neg. battery cable and remove the rear SAM. You the videos below to open up the module . In the second video, pry up each tab and insert a round tooth pick to hold the tab open and then go to the next until you can separate both covers.
Make sure you also remove the black pin housings as there will be corrosion under them. Use Electronic Contact Cleaner in spray can to clean the entire board with a toothbrush.

Hi, looking for help with the problem i have with both keys failing to lock or unlock my 2006 Ml 320cdi. All worked fine until my main battery went flat, jumped the car and all was well. Drove home, doors locked, then unlocked, locked again then refused to work by the key. Recharged battery fully, replaced batteries to both keys but keys wont sync.
Put the icarsoft scanner on the car and no faults were recorded, checked rear SAM and no codes were thrown up. Can anyone help?

What do you mean by the above? Did the lock and unlock happen on its own or did you lock and unlock?
Do you have another key?
When you jumped the battery, was the key in the ignition?

You will need a scanner type code reader to scan the entire veh.

When you are jumping a M/B veh. the key must not be in the ign. in any position. The DAS control Module has now been scrambled. Codes will be stored in the DAS & EIS and ECM Modules.
You will need a scanner type code reader to scan the entire veh.

Melvin, you must understand there since you are not able to start the truck, there must be codes stored somewhere. I do not know the capability of your icarsoft, that is why I suggested getting a scanner that will read codes in every module.

If you read my messages you will see the car started, have been restoring cars for many many years and have full knowledge of how to jump start a car. My question was could anyone help with the fact that since jump starting the car the keys would not lock or unlock the car. The iCarsoft scanner is capable of scanning the entire car and allows for full resetting of various modules and also facilitates the changing of values, this had shown no faults either current or historic. At this time the car strays runs and drives as it should.

I'm not interested in your previous knowledge and restoration abilities, but in post #13 you asked this question, " How would you jump start a car (any car) without the key in the ignition"? to which I responded. Then why did you ask this question?
