Investigating P0440 on Your 2024 Volkswagen Atlas
Your 2024 VW Atlas has triggered a P0440 code — an EVAP malfunction. The refreshed Atlas uses a 2.0L TSI turbo (269 hp) with 8-speed automatic and available 4MOTION AWD. As a new vehicle under warranty, this is likely minor. 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 Atlas drives perfectly normally. TSI engine, 8-speed, and 4MOTION are unaffected.
