Sorry I can't provide a pin diagram but there is only two reasons why an injector might be permanently open - either it permanently has a supply and a ground or it has suffered mechanical damage (grit, dirt or salt ingress for instance). Checking for current across the injector terminals with a test lamp or noid light would be the quickest method to begin. If the test lamp lights and/or the injector closes when disconnected there is either a wiring fault or an ECU fault. I think when you study the wiring diagram you will discover the injectors have a permanent supply and the ECU provides the ground path so if a wire chafes and contacts engine or body metal between the injector and ECU, the injector will remain open.

no its the wiring fault.
check the wiring

Hello, guys, you can have a look at the ECU CHIP TUNNING TOOL

Sorry, did a search around and could not find one

wiring harness can be over $2k, the labour is high. i would question the reasoning behind this. i lost a wring harness on a 99M3 because the ECU blew, because the ecu gets wet on bmw and malfunctions...

on your car i dont' know. check the condition of the ecu and see if is has corroded because water is getting into the compartment.

TW: i got a $2500 wiring harness on ebay for $50
and a replacement ecu for $100


cost me $500 in labour and another tow to bmw and $100 for them to program the new cu to my ignition key.
from BMW, yes this would be pricy.
