first time merc owner many dtc and warning lights on and warning messages

[Rogrr]

Hi

I have DTC P0101 P0500 P0600 P0700 P0720 from obd2. The ABS light is on and I have break wear BAS and ESP warnings.

I tried cleaning the maf and make sure there are no intake leaks. But P0101 keep coming back. Maybe I need a new maf? Can I retrofit the Bosch maf to the right angle maf on mine?

I suspect the harness from the brake wear sensor and speed sensor on the left front is worn by the battery tray.

I have yet to check the transmission errors.

Cleaned the gearbox and etc harness. Replaced the esp module and lateral acceleration sensor and a yaw rate sensor has been ordered. Replaced the broken brake stop switch. Limp mode is gone.

I also cleaned the maf and removed the alarm siren and replaced the blown fuse 8.

I've similar issues and am new to Mercedes. I've the orange engine light, bas and abs lights on. Diagnostic said passenger speed sensor so replaced and got code clear. Lights were off for about 5 miles then all back. Would worn brake pads cause any of these issues. Getting a different guy to do diagnostic next week.
