Where is the carbon canister located in an Audi A4?
2 Answers
It is located inside the left rear body panel, and you can easily find it by lifting the car. Here is some relevant information about the Audi A4: 1. Introduction: As the first model to introduce the long wheelbase and turbo concept, the A4L has maintained strong sales from the B5 to the B8 generations. The new A4 has abandoned the teardrop headlight design, added quattro all-wheel drive, and features a more stylish and sporty exterior with outstanding power and handling. The interior is finely crafted, equipped with advanced technology, and offers ample space, making it highly practical among B-segment vehicles. 2. Achievements: The Audi A4 produced by FAW-Volkswagen is the first B-segment luxury sedan from an international brand in China, filling the gap in the domestic B-segment market and solidifying FAW-Volkswagen's leading position in the domestic luxury car market. This was quite significant at the time, and judging by the sales of the Audi A4 in China, it has indeed been successful.
My old A4's charcoal canister is located inside the right rear wheel arch, which I discovered last time when changing the brake pads myself. You have to remove the wheel arch liner to see it – a dusty box connected to three tubes, secured to the chassis beam with zip ties. When changing brakes, it's best to check its attached solenoid valve as well; if that gets stuck, you'll smell gasoline. Last time my car had idle vibration, it turned out the charcoal canister's tube was cracked by a stone and leaking air. If you're handy, you can replace it yourself, but pay attention to the new canister's arrow direction – it must align with the airflow. Installing it backward will cause fuel tank pressure issues.
