Hi, my ride is a 330Ci M3 2006, I have replace the secondary air pump along with the valve the old one was jammed ounce replace found out that the 50 amp fuse was blown so replace it check the salmon air pump relay it is good. Still not working in first morning start get error code 2762 , when I force the air pump trough the scanner tool I get the system to work thus proofing relay, pump, wiring to the pump, also check the O2 sensor ahead the air pump getting 1.2 volt, could it be the DME not sending the proper command to start the pump, the mechanic is telling me they are going to re-flash the ECU, please shed some light. thank you for your advices
