Got a P0440 code on your Bentley Continental GT W12? Don't stress! This code means you have an emissions leak, and while it won't stop your car, it will stop it from passing its MOT.
In this video, Nige from Bentley on a Budget gives you a methodical, no-nonsense guide to diagnose and fix the P0440 code. We'll show you how to start with the simple fixes and work your way to the more complex ones, saving you a fortune in garage bills.
Here's the plan:
The Easiest Fix: We check the fuel cap, the #1 culprit for a P0440 code.
Next Steps: We inspect the EVAP hoses and lines for cracks and leaks.
Component Check: A DIY guide to testing the purge valve and vent valve.
Advanced Diagnostics: How a smoke test can find a hidden leak that nothing else can.
Don't let a simple emissions leak be the reason your Bentley fails its inspection. Watch this guide to arm yourself with the knowledge to sort it out yourself.
