My gf has a 02 beetle and out of the blue it won't start. The EPC light and check engine light are on. I checked the codes and 9 codes popped up. I just checked the codes a day before and there was nothing. Codes for cylinder injector circuit low 1 2 3 and 4 came up along with secondary air injection system switching valve a circuit shorted , A camshaft position actuator circuit bank 1, secondary air injection system relay A circuit malfunction, evap system purge control valve circuit shorted, and HO2S heater control circuit low bank 1 sensor 2. Where do I even start????????
