No Power with 10 Codes
My 2017 gle350 has been going strong (90k miles) until yesterday. Turned it on and it barely has any power and check engine light is on. Scanned it and got 10 codes! P2088 p2090 p0343 p0368 p0300 p0301 p0302 p0303 p0351 p0352. Anyone have this? Can’t be everything failed at once. I'm thinking it’s some sensor that’s throwing everything off but not sure where to start. Thank you!

Your engine is likely running in limp-mode to preserve itself.
Go ahead and translate your codes into descriptions so we can begin to understand more details.
I am guessing something electrical is bugging your engine computer.
How old is your system battery?
Any recent service done?
@90k the alternator shoukd still be fine unless the old serpentine got shredded.

missing codes description
Your best course may be to take the time to translate your code numbers into English descriptions to make some sense.
A pro will do that preliminary research to guide his repairs. Without clues you're left to replace good parts.
