HI Guys,
im having an intermittent problem with engine light coming on and its seems it is due to the emission control.
Ive replaced one of the N112 solenoid valves that operate flaps, ive run secondary air injection pump connected straight to the battery and it seems spin fine and quietly, and replaced new EVAP Purge Control Valve (N80).
Could anyone advise me please in next troubleshooting steps? below is read out from the scan, can i do any in depth analysis with rosstech on the codes below and secondary injection air pump?

cheers
joe

Did you overlay or check wiring for open for feed consumer BUS and current tracks back to ECU yet for respective components?

Fuses!

Am I right to think that engine components like purge valve related fuses would be in the engine compartment fuse box ? Car is multivan T5 v6
