Hi,
I noticed in the E48 wiring diagram that I need a 20amp fuse, and a relay can anyone tell me what amperage does it actually draw whilst cranking and normal running?

Regards

The diagram shows perhaps a heavier fuse than essential, because it also shows all related power from same fuse.

ie injectors, coils, ecu, other actuators.

The actual ecu itself would consume very little power. Injectors a bit more, coils potentially more etc

But even the above will depend on what injectors, what coils etc.
