Bmw 318i E46 doesn't Start

[J.C]

Good day. I bought a BMW 318i E46, But it doesn't start. It is swinging, I replaced the computer box and now the car is showing overheating and I know it won't start then. How do I fix the problem?

Please help me urgently.

If you replaced the computer box you need to pair the engine ECU and the EWS controller if I am not mistaken???

:idea:

My car had the same issue: Servo motor (R4k)and Eccentric Shaft Sensor (R7k). Starting again.

Gizmo wants nothing to do with the E46 318i...

OP do a diagnostic with the original ECU fitted, you cannot just swap another ECU as it won't work.
