Market analysis
How much does a used Tesla Model 3 engine computer cost?

Buying a used engine computer: what to check
- Match hardware and service numbers: Ensure hardware revision codes and circuit board part numbers match exactly, as pinouts change mid-model year.
- Inspect multi-pin connector headers: Check header pins for bending, green copper oxidation, or burnt circuit board traces inside the wiring sockets.
- Verify immobilizer programming requirements: Plan for anti-theft security relearn procedures or ECU re-flashing before the replacement computer will start the engine.
- Confirm donor transmission and emissions spec: Ensure the donor vehicle used the same transmission type and regional emissions package to prevent fault codes.
- Check aluminum casing seals: Inspect housing screws and perimeter rubber gaskets for white oxidation or breaks that indicate past water intrusion.
