OK, need some additional input. Car is a 2008 335i. Had 30BB, got the defective MOSFET replaced and reinstalled the ECU. Also replaced coils/plugs.
The car cranks but never starts. Before removing the ECU, the battery was disconnected. After the MOSFET was replaced, the ECU was reinstalled then the battery was reconnected.
There are no codes stored, which makes me think the repair was successful. Before clearing the codes immediately had 30BB come back.
Please tell me I am missing something simple here. Is there some step that needs to be done after the battery is disconnected? The guy working on my car disconnected and reconnected the ECU, so everything looks seated well.
