Investigating P0440 on Your 2024 Volkswagen Taos
Your 2024 VW Taos has triggered a P0440 code — an EVAP malfunction. The Taos uses a 1.5L TSI turbo (158 hp) with an 8-speed automatic or 7-speed DSG (4MOTION). 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 Taos drives perfectly normally. TSI engine and transmission are unaffected.
