Has anyone seen this message before? and could chime in on what it possibly means? This is not in the owners manual and off a quick search in this forum I did not find anything!
If you don’t have one, go and purchase a high quality code reader so that you can plug into the OBD II port and find out what the issue is. Probably a suspension issue I’m guessing

I have a Bosch unit that I picked up spur of the moment at O’Reilys iirc. Works well, although it’s a couple of years old now and I’ve never had to use it on the AMG, just the wife’s Jeep. Constantly! lol
Always make sure that the unit you buy includes the manufacturer/model year, etc. for your specific car.
I'm not an expert, but I don't think a code reader will give you anything here. This seems to be a suspension issue, not an engine issue.
I would try a reset - disconnect the battery, wait a few minutes, then reconnect. Make sure to disconnect the correct polarity (not sure whether + or - is best).

If anyone knows anything let me know!!
I had the same chassis malfunction message on my dash. Fault was a failed dynamic motor mount on the driver's side. You would need a higher end scanner than just a simple OBDII reader. I bought an Autel MS906BT for $1200 on AMZN as it does detailed diagnostic scanning on most systems on virtually all brands. I have many cars so it is useful to get a comprehensive diagnostic scanner which can also reset many systems. For example on my wife's 2019 Cayman, it is the only way to reset the engine oil change indication after and oil change, or else you have to take it to the dealer.
Motor mount was replaced under warranty, and all is well. It did not seem to be a problem to replace even though my dealer had not done it before
Were the vehicles tuned at all before this? When I tuned mine with DME Tuning, this error popped up at first, but after a bit of a drive it disappeared and I haven't seen it since. Knock on wood.
I can tell you where to find the Bank 2 Intake Cam Sensor. Pictures are extremely difficult to find BC this engine is loaded with ancillary equipment. If you can follow my attempt to get you there....
Before we go there - A P002177 is what is defined as an "implausible error" meaning the EMS is receiving a signal that is outside any known parameters it should be seeing. In other words, a signal it cannot process..."off the map" so to speak. On these engines, a probable failure is that the cam stator shifts and is common with a P002177, maybe more common than a failed camshaft sensor. That means the stator has rotated on the camshaft making it no longer in an operable position to make sense to the EMS. This, normally, would require resetting the camshaft and stator (and LOTS of factory specialized jigs)
Since in your case, the CEL cam is coincidental with the engine washing, you might be lucky with a failed sensor.
OK, so where is the sensor? It is on the LEFT bank, bank 2. Left and right is ALWAYS determined when you're sitting in the driver's seat looking out the windshield. So, left bank is on the driver's side of a LHD car. My pic, unfortunately, is showing the RIGHT SIDE Bank 1, so you need to "use your imagination" and sort through the info switching sides. Again, this is BC I couldn't find a single pic showing the LS, Bank 2.
So, here goes - The red arrow shows the exhaust cam, bank 1, and the yellow circled sensor is the EXHAUST cam sensor on the right bank, bank 1. The blue arrow shows the INTAKE cam BANK 1, and out of the pic you would see a similar sensor to the yellow circled one and that would be the INTAKE cam sensor, BANK 1.
Now you need to switch your search to the other bank, BANK 2 where the P002177 resides, and find the INTAKE cam sensor. It will be closer to the fender, not closer inboard.
The green arrow, BTW, is the exhaust cam solenoid, bank 1. There is a solenoid for each of the 4 cams. This is NOT the part for which you're looking.

yay! thanks for your time and thanks for trying to help me!
I will try to inspect that sensor (the other side that picture says), I hope it will be just it as resetting camshaft and stator sounds money!
And i guess i need some kind of better code reader..
The best code reader for MB is SDS "Star Diagnostic System and that's what I use. There are MBworld vendors that can get you set up with such a system.
You'll find that they are more actively involved in the threads for SL55, SL65 etc as there a more D.I.Y members.
As I still have an SL55 and an S65 I have always used the SDS system as I do all my own work. In January I acquired my 2017 AMG GTS (with a frozen engine) I have installed a replacement motor since and in the process have made extensive use of SDS system.
Thanks for suggestion! I will take a look! I am also looking into : Launch x431 4.0 Pro looks interesting, and fit more cars..
Anyway found a sensor, super tricky to check.. Need to remove some parts to get there!
I guess I will book the service visit..
Thanks
let me know if you get the X431 and if you like it. I have about 3 scanners, all under $300, but none of them are bi-directional and they can't read transmission codes/temperature etc... I'd love one that does and not sure I want to get into star/SDS
