W221 Hybrid Errors
Hello,
I don't know why my W221 shows so many error messages. The car began with these issues after a visit to an authorized MB dealer, and I believe they did a software update.
I replaced the main battery. I have no error message related to the hybrid or the small battery inside the dash. The hybrid battery is around 70% charged.
The car sometimes starts and sometimes doesn't. After it starts, it is drivable, and I don't see any loss of power. Turn signals don't work during errors.

What should I check?
