I recommend to have the throttle valve thoroughly cleaned, possibly it is jamming.2514 (001) R39/1 (Vent line heater element)- Short circuit to positive2514 (002) R39/1 (Vent line heater element)- Short circuit to ground 2526 (001) Y77/1 (Boost pressure regulator)- Short circuit to positive2526 (002) Y77/1 (Boost pressure regulator)- Short circuit to ground2526 (004) Y77/1 (Boost pressure regulator)- Signal line is interrupted.2527 (001) Y27/11 (Exhaust gas recirculation positioner)- Short circuit to positive2527 (002) Y27/11 (Exhaust gas recirculation positioner)- Short circuit to ground2527 (004) Y27/11 (Exhaust gas recirculation positioner)- Signal line is interrupted.2527 (008) Y27/11 (Exhaust gas recirculation positioner)- Thermal overload of control module N3/21 (CDI control unit 2904 (001) Y77/1 (Boost pressure regulator)- Short circuit to positive.2904 (002) Y77/1 (Boost pressure regulator)- Short circuit to ground2904 (004) Y77/1 (Boost pressure regulator)- Open circuit2904 (008) Y77/1 (Boost pressure regulator)- Thermal overload of control module N3/21 (CDI control unit)2905 (001) Y77/1 (Boost pressure regulator)- Positioner signals fault.

Possibly one of the listed components has a short circuit in it, causing the ECU overload. It can be pinpointed by disconnecting them one at a time, to see if only one will trigger the codes. If the throttle valve is not jammed, it can have internal short circuit. Best Regards,Stan
