An A160 with a few issues

Long story short, I got an W168 A160 which was ACS but was then fitted with clutch pedal and pump.
All was OK for a short period of time and the all time favorite "F" started coming again. I drove it for some time like this until I got it to a Star equiped friend to clear and re-read the codes after some driving.
So here are the new codes that came up:

ECM - Engine control monolith

P0121-022 M16/6 (Throttle valve actuator) : The signal voltage of component B2/5 (Hot film mass air flow sensor) is implausible in comparison to the value of an actual value potentiometer.


ACS - Automatic clutch system (left most of it so the car can start)

P1747-008CAN fault ( Possible cause : Fault in CAN communication with
P0700-002General system error ( Possible cause : Limit value for adaptation of characteristics )



ESP - Electronic stability program

C1022Fault in CAN communication with control unit N3/5 (ECM control module).


LCP - Lower control panel

B1024 Failure of CAN low at module N72 (Lower control panel control unit)



DCM-RL - Door control module rear left

B1155 Component S21/3 (Left rear power window switch) is operated for more than 25 s or cable has T .

DCM-RR - Door control module rear right

B1155 Component S21/4 (Right rear power window switch) is operated for more than 25 s or cable has T .



RFL - Radio frequency locking/electric central locking

B1101-002Control line for lock switch 2 (lock): PSE , Convenience feature , ATA : T . If no lock switches are fitted, the fault can be ignored.


I'm thinking this time either the throttle valve or the ECU/MAFS is giving me headache, but wanted to as the more advanced than me users here for a hint.


Thank you
