These are the reasons your vtec is not working.
17 is the speed sensor. Your ECU has to detect your speed before engaging vtec.
and 21 is the VTEC solenoid. You probably have a bad connection or faulty solenoid. I would check the wiring to the A4 pinout using a digital multimeter to verify the connections.
For VTEC to run properly, you must clear those codes.
