Tracking Down P0440 on Your 2024 Volkswagen Tiguan
Your 2024 Volkswagen Tiguan has flagged a P0440 code — an EVAP system malfunction. The third-generation Tiguan features a 2.0L TSI turbo four-cylinder (184 hp) with an 8-speed automatic and available 4MOTION AWD. As a new vehicle under VW's warranty, this is likely a minor issue. Let's examine 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 Tiguan drives perfectly normally. The TSI engine, 8-speed, and 4MOTION are unaffected.
