⚠️ Seeing fault code 36E2 on your Mini?

🧰 Replaced sensors but the code keeps returning?

🛠 We repair MEVD17.2.2 ECU faults at the root—fast, permanently, and with a lifetime warranty

If your Mini has logged fault code 36E2 – 5V Sensor Supply Voltage Out of Range, you’re not alone. This issue is frequently seen on models fitted with the Bosch MEVD17.2.2 ECU, especially in the Mini Cooper S and John Cooper Works (R56, R57, R58) range.

Many drivers and even workshops replace sensors like the MAP, throttle, or boost pressure sensor—only to find the fault returns immediately. That’s because the true source of Mini 36E2 is often internal ECU failure—not the sensors themselves.

At ECU Fix, we offer a tested, reliable repair service that restores full 5V supply performance and eliminates fault 36E2 permanently.


🔍 What Does Mini 36E2 Actually Mean?

The full fault description is:

36E2 – 5V Sensor Supply Voltage, Line Too High or Too Low

This means the ECU’s internal 5V regulator—which powers various engine sensors—has drifted outside safe operating range. It may supply no voltage, drop intermittently, or spike. This causes affected sensors to throw multiple faults or behave unpredictably.

In most cases, the ECU itself is the source, not a shorted sensor or wiring fault.


⚠️ Mini 36E2 Fault – Common Symptoms

If you’re dealing with Mini 36E2, you may notice:

  • Persistent engine warning light (EML)
  • Other sensor-related fault codes present
  • Loss of power or limp mode
  • Faults with MAP, throttle, boost, or pressure sensors
  • Intermittent sensor dropout
  • Code returns after replacing related sensors or wiring

When multiple unrelated sensors show errors—and especially when they share a 5V supply—the ECU is likely at fault.


🛠 How We Fix Mini 36E2 ECU Faults – Bosch MEVD17.2.2

Rather than replacing the entire ECU or continuing to swap sensors, we target the underlying fault—a failed or unstable 5V regulator inside the MEVD17.2.2 control unit.

Our service includes:

  • Bench testing of 5V supply and output rails
  • Diagnosis of shorted, open, or floating supply circuits
  • Replacement of faulty voltage regulation components
  • Stress testing of repaired ECU under load
  • Full report and lifetime warranty

We eliminate the fault at source, so you can refit your ECU and be confident it won’t return.
