Restore Functionality to Your Hybrid or Electric BMW

The BMW Electric Motor Electronics (EME) control unit is essential for hybrid and electric models, managing energy flow between the high-voltage battery and electric motor.

When a used EME is installed, the immobilizer must be reset — otherwise, the vehicle will not start in forward or reverse gear. Even with a healthy battery and electronics, the drivetrain will remain locked.

Our BMW EME immobilizer reset service provides a fast, plug-and-play solution to restore your vehicle’s functionality without expensive new parts.

Why Your BMW Needs an EME Reset

If you’ve replaced your EME with a second-hand unit, it remains coded to the original vehicle. Unless reset, the immobilizer blocks the drivetrain, preventing start-up.

Common Reasons for EME Immobilizer Problems

• Installation of a used EME control unit

• Replacement after EME failure

• Battery disconnection or replacement

• Coding/programming errors during repair attempts

• Software mismatch between EME and vehicle

Symptoms of a Locked BMW EME

Not sure if your immobilizer is blocking the EME? Look for these warning signs:

• Vehicle will not start in drive or reverse

• “Drivetrain malfunction” error on iDrive

• Electric motor unresponsive despite charged battery

• Fault codes linked to immobilizer or EME communication

• Vehicle remains inoperable even after coding attempts

Common BMW EME Fault Codes

• 21F0E2 – Start enable not granted

• 21F102 – Immobilizer active, start not possible

• 21F159 – No communication with immobilizer

• 21F1E0 / 21F1E1 – EME internal fault due to lock status

• 21F14A – Drivetrain locked, forward/reverse gear disabled

If your diagnostic scan shows any of these codes, an EME immobilizer reset is required.
