Tracking Down P0440 on Your 2024 BMW 5 Series
Your 2024 BMW 5 Series (G60) has flagged a P0440 code — an EVAP system malfunction. The all-new G60 generation offers the 530i (2.0L TwinPower Turbo, 255 hp) or 540i (3.0L inline-six, 375 hp), both with an 8-speed automatic and available xDrive. BMW's EVAP system includes the manufacturer-specific leak diagnosis module (LDM). As a new vehicle, this is likely a minor issue. Let's gather the evidence.
Symptoms to Watch For
- Check engine light illuminated
- Faint gasoline odor
- Slight fuel economy decrease
- Fuel nozzle clicking off early
- Failed emissions inspection
Your 5 Series drives perfectly normally. Engine performance, 8-speed, and xDrive are unaffected.
