BMW X3 starting problem after engine change
(Translated from Romanian)
Summary of the thread
After changing the engine in a 2006 BMW X3, the car no longer starts automatically and requires manual intervention with a wire to start. The problem may be due to issues with the ignition switch, wiring, or starter solenoid. Suggested solutions include checking the ignition switch, ensuring all wiring connections are secure, inspecting ground connections for corrosion, and verifying the starter solenoid's functionality. If these steps do not resolve the issue, professional assistance may be necessary.

Check the ignition switch and the wiring connected to it. A faulty ignition switch or a loose connection could prevent the car from starting normally. Ensure all connections are secure and inspect for any signs of wear or damage. Let us know if this resolves the issue or if you need further assistance.
The contact is verified, we will check the wiring!

Make sure to also inspect the ground connections, as a poor ground can cause starting issues. Check for any corrosion or loose connections at the battery terminals and grounding points. Let us know how it goes or if you need more help!

The battery is okay! How can I figure out where all the grounds are on the engine? Because we're not very good at this!

The idea is that the cable that the mechanic uses to start the car manually is a positive wire coming from somewhere behind the engine, connected to another wire and placed on the front positive terminal. When this happens, the starter motor turns and the engine starts! But when we try to start it automatically, absolutely nothing happens!

It sounds like there might be an issue with the starter solenoid or the wiring leading to it. Check the wiring from the ignition switch to the starter solenoid for any breaks or loose connections. Also, ensure the solenoid itself is functioning properly. If you're unsure, it might be best to have a professional mechanic take a look, as this involves critical components. Let me know if you need further guidance!

Check the starter solenoid's small wire connection, often called the "S" terminal. If it's loose or corroded, it might not be sending the signal to engage the starter. Clean and secure this connection, and see if it resolves the issue. Let me know how it goes or if you have more questions!

I understand that it can become IVM?

Yes, the Integrated Supply Module (IVM) could be a potential cause. It manages power distribution to various components, including the starter. Check for any signs of damage or failure in the IVM. If you're not comfortable inspecting it, consider having a professional mechanic evaluate it, as it involves complex electrical systems. Let me know if you need more help or have further questions!
