The car is 335xi twin turbo with direct injection.In the first part of this video i quickly show injector test. talk about index numbers .and how to calibrate direct injection injectors. What you couldn't see in the video was the LED test light flashing. It would flash until i plug in injector. Then would cause all of bank 1 (cyl 13) to shut down Unfortunately i ran out of memory before diagnosing the problem inside the engine computer. So i will make a short video on that as well..
