4 Answers
Citroën air filter replacement method is: 1. Open the engine hood and locate the air filter; 2. Gently release the two clips securing the filter box cover, then lift the entire air filter box cover; 3. Lift the air filter box cover and remove the old air filter; 4. Install the new air filter, close the box cover, and fasten the clips. Taking the 2018 Citroën DS5 as an example, it belongs to the mid-size car category with body dimensions of: length 4530mm, width 1871mm, height 1520mm, wheelbase 2727mm, fuel tank capacity 60L, and curb weight 1600kg.
I've changed the Citroën air filter several times, and it's quite simple. First, open the hood and find a quiet environment to avoid excessive dust harming the car. In the engine compartment, there's a square box near the front, usually made of black plastic. Make sure the engine is cool before opening it. The screws may require a wrench or can be unscrewed by hand. When removing the old filter, do it gently to prevent dust from falling into the pipe. Buy an original replacement filter from the official Citroën website—it’s only a few dozen bucks and not expensive. When installing the new filter, pay attention to the arrow direction, aligning it with the air intake direction; otherwise, the filtration efficiency will drop. Close the box securely and tighten the screws without overdoing it. I replace mine once a year to improve fuel efficiency and power while protecting the engine’s lifespan. The whole process takes less than twenty minutes, and all you need is a basic screwdriver. Do it during routine maintenance and check it regularly—it never hurts. Remember, a dirty filter increases fuel consumption, so replacing it early saves hassle.
I just learned to do it myself, and even a beginner can handle it. Open the hood and locate the air filter box. For Citroën models like the C3, it's a plastic case next to the battery. Wear gloves, use a screwdriver to loosen the screws, open the lid, and remove the old filter. Check its color—if it's blackened, it's time to replace it. Buy a new filter online that matches your model. When installing, pay attention to the arrow direction to ensure proper airflow. Close the box and tighten the screws back. The whole process is quite easy and effortless, taking me only 15 minutes. It's recommended to replace it every 12 months or 10,000 km to prevent engine contamination. Doing it yourself saves money and time while learning some car knowledge. By the way, clean the dust inside the box, but avoid using a blower as it may push debris into the engine. Keep the operation clean and prioritize safety—it's much faster than going to a repair shop.
Changing the Citroën air filter is simple and saves money. Doing it yourself by buying a filter costs only a few dozen bucks, saving more than half compared to a repair shop. Open the hood and locate the filter box, usually it can be opened by hand or with a small tool. Take out the old filter and check if it's gray—replace it if it's dirty. Buy reputable brands online, don’t go for cheap knockoffs. Install the new filter with the arrow pointing in the airflow direction, otherwise efficiency drops. Close it properly and tighten the screws. I change mine once a year—DIY takes just ten minutes, and the tools are basically free. Remember to operate when the engine is cold to avoid burns or sucking dust into the pipes. Better airflow can slightly improve fuel efficiency and extend engine life. Citroën models don’t differ much; the filter locations are similar. Timely replacement prevents other issues from building up—regular checks save big money.
