I have a 99 bmw 323i and the engine light came on, I used the obd-2 tool to check
the code and it gave me a P1470 Leakage Diagnostic Pump Control Circuit Electrical code, does anyone knows how to fix this?

Cool

code indicates that the pump that measures pressure in your EVAP system is not working.

check ALL fuses first. Hopefully it isnt the pump itself ;-)
