Thanks for the info. Will have BMW double check and verify. I'd be pretty annoyed if they didnt know about this incompatibility ahead of time. They advised me that it wouldnt matter as long as I replaced all of them at once. To clarify, the parts department did. The tech's installed it for me so youd assume they would have verified this...I'll find out tomorrow what's going on.

Direct injection fuel systems operate at significantly higher pressure than a conventional port injection fuel system. Due to the design, the engine really relies heavily on a properly operating fuel system. If your BMW is suffering from misfires or has a rough idle it can be due to faulty fuel injectors.
Also replace decoupling element 13537577649 when installing new fuel injector.
Note: Per BMW service bulletin SI B13 03 15 the injectors in the vehicle may not match with what is listed in the BMW ETK. Identify the injector installed in the vehicle using ISTAD 4.04 or later test plan using the following path:
Vehicle management - Service Functions - Powertrain - Engine Electronics - Injector Determination
Test plan will state, "this engine required EU# injectors". This fuel injector is for vehicles with an EU5 designation and will not work on a vehicle with a different designation. On N55 powered vehicles this injector is used on vehicles equipped with a Bosch high pressure pump.
