Q: My BMW has P0204 (cylinder 4 injector) but the injector tests OK — what’s wrong?
A: P0201–P0208 are circuit fault codes on BMW. A corroded 2-pin connector at the injector produces the same code as a failed injector. Inspect the connector before replacing the injector or coding a new one with ISTA.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
