I got this message a few weeks ago. I found it was intermittent for a fews days even showing 14v sometimes other times 11-12v. Ended up finally failing.
Replaced the alternator with a new bosch one and all has been well for the past few weeks.

Hi
Hello I dropped my phone broke my screen phone was getting service the past couple of days sorry about that tomorrow may get a voltage load reader to be positive that both my batteries are performing properly underneath a load and then I'm going to check the load on my alternator while it's running with the device I'm about to buy and then I will determine on if it's my brand new alternator Bosch alternator I got is defective or my Bosch battery in the trunk or the Mercedes battery underneath the hood to auxiliary battery or my voltage battery regulator located in the trunk, for the most part I checked my computer's my Sams all nice and clean and brand new looking then inside the car underneath the car is extremely clean not a speck of rust was always stored hardly driven in the weather

Hello
Difficult to say...my experience was a wild ride. I changed the aux battery, the trunk battery, relay on aux battery, bcm, VR, alternator, and nothing helped the fix until I bought a used front SAM (driverside fuse box in engine bay) and it got fixed. However, there was a penny stuffed in the cigarette lighter that keep blowing the fuse. Good luck.

Well
I'm going to check my batteries tomorrow the loads on them and then while it's hooked up I'm going to check my alternator and that checks out and then I'mma check my voltage regulator load regulator that's in the trunk change that out and if that still don't work but I know it's the same underneath the hood but before I replace that I'm just going to pay 200 for a shop to tell me exactly what it is

MBWorld Fanatic!
I recently had these two error pop up. I checked the battery voltage for both battery and checked out good with 12.7 off-14v at idle.
I decided to replace the smaller battery and still both errors are present.
I went to go get it checked with star and the results came out that its possible that its alternator or front sam module could be the issue.
My questions is that how can the alternator be at fault when it has correct voltage with engine off and on?
Could it be front sam? Does anyone had this issue before? Also, my ESP light dont come on anymore when i stomp on it. Gotta say this is a weird issue.
By the way, i have a 2006 cls55, but i know you guys with the e55 have similar issues as well.
