Electronic Rear axle differential lock currently unavailable
I have a 2016 AMG GTS.
I occasionally got this message when it rained, but it went away for weeks. The last month or so get it every day within about 60 seconds of driving. I don't have star/xentry and my MB V2.0 doesn't read any error codes from the transmission. The car drives "fine" and doesn't go into limp mode, I just get this error. I'm going to take it to a shop with star/Xentry before I go to the dealer and see if they can figure it out. The message is different to some of the other posts I've seen where someone had a similar error from an GTC.
Wondering if anyone else with a GTS has seen this error and how did they end up getting it resolved
?
It's a known issue with the e-diff on some older cars, not just the GT. There's a service campaign for it as far as I know. It's a software issue, but I think some have gotten the whole diff replaced under warranty if I'm not mistaken.

thanks, My car is no longer under warranty so I guess I'll have to see if its covered under recall.

if you are anyone knows the campaign number please let me know. I didn't find anything under "safety" recalls as this probably doesn't apply to a safety issue.

Sorry, I don't have it. I only came across this in a couple of threads. If you do a search here you should find several threads. Maybe you'll find it in one of those. You can also enter your VIN here https://www.mbusa.com/en/recall and it's supposed to bring up all recalls and service campaigns for your car, but it doesn't seem to always bring up the campaigns.

Thanks, I tried the MB site before and it shows 0 recalls and campaigns. I did some searching too and didn't find a specific campaign number. I'll see how my appointment goes next week
Have you done the drive shaft replacement recall? If so you don't need a number for software upgrade or warranty for either recalls.. Just call a dealership and scheduled to have them done.

based on my VIN number, my car was not included in the recall.

If I am not mistaken the recall later on was extended to all 2016 models. Also it was based on the drive shaft serial number so it is a good idea to have it checked.

the update, took it to a local shop that deals with quite a few higher end cars including GT cars and exotics. They inspected the diff, wiring, and wiring to the rear sam, under diagnostics, they found no codes stored.
They did update all the modules via DAS/XENTRY and the issue appears to have gone away, over 100 miles driven. Typically the issue comes up within 1/4 of a mile. Fingers crossed this solved the issue.
They also noticed my alignment was way off, had was too much toe front and back, so they ordered shims from MB and got it aligned.
unfortunately, the error code came back after about a week, has about 120 miles on it since the modules were updated, it came on about 20 minutes into local drive today and now comes on every time the car is re-started. guess I'm going to MB.
There are no codes stored in the system, just the dashboard warning in my OP.
The problem with that error code is that it is a general error. It is not specific to what the issue is - and even with the codes read, the mechanics had to do some guesswork. In my case they had AMG's technicians look over the data. The issue on my GTC ended up being a Powertrain Control Unit module, though I never got to test it out myself as the car was bought back.
I hope they can find the issue with your car soon! All I know is that another 18' GTR had the same issue, but it ended up being some wiring in the trunk that would occasionally move out of place.

Thanks I've seen your post and the GTR wiring one. Hopefully a smart tech can figure it out, I don't want a new diff as its out of warranty
Took it to Mercedes, they found stored codes that showed one wheel reading a different speed to another. They checked the wiring harness and cabling and found no issues.
They said it could be due to my wheels/tires (I bought the car used) it has 305's on the rear instead of 295's. They cleared the codes and did a software update. guess I'll see what happens.
Feels like a lot of folks run different wheel/tires without issue so surprised if that really caused the issue.
