I hope i can get an advice. Have an Audi A6 2001 2.8. Had a "coolant temperature sensor" code. My mechanic replaced the sensor and also he replaced a bad fog lights fuse. After the job was done the car is not idling correctly. Check engine came back and got 12 different codes:
P0444- evap emission control system purge valve c open
p0418 secondary injection system relay A malfunction
p0010 Camshaft Position Actuator A Bank 1 Circuit Malfunction
p0412 Secondary air injection system valve malfunction

p0102 MAF or VAF A Circuit low imput

Mechanic is not answering my calls. can not afford to spend money on this car anymore.
