Hey everyone! Today, we're diving deep into the 2011 Mitsubishi ASX 1.8 DI-D 4x4. This compact SUV was a popular choice back in the day, known for its fuel efficiency and all-wheel-drive capability. But, like any car, it has its quirks. If you're considering buying one, or you already own one, this guide is for you. We'll be looking at the most common problems you might encounter and, more importantly, how to fix them. Buckle up, let's get started!

Engine Troubles: Diesel Engine Woes

Let's kick things off with the heart of the matter: the engine. The 1.8 DI-D diesel engine in the 2011 ASX is generally pretty reliable, but it does have some potential issues you should be aware of. One of the most frequently reported problems is related to the diesel particulate filter (DPF). Over time, the DPF can become clogged with soot, especially if the car is mainly used for short trips. This can lead to a loss of power, reduced fuel economy, and, in severe cases, the engine entering limp mode. If you see the DPF warning light on, it's time to take action. The solution often involves a forced regeneration cycle, which burns off the accumulated soot. You can try driving the car at a steady speed on the highway for about 20-30 minutes to allow the DPF to regenerate naturally. If that doesn't work, you might need to take it to a mechanic to have the regeneration performed or, in worst-case scenarios, the DPF replaced. This is a common issue with diesel cars in general, so it's not unique to the ASX.

Another engine-related issue that owners have reported is problems with the fuel injectors. Faulty fuel injectors can cause rough idling, difficulty starting the engine, and decreased fuel efficiency. If you suspect a fuel injector problem, it's crucial to get it checked out by a qualified mechanic. They can diagnose the issue and replace the faulty injectors if necessary. Ignoring fuel injector problems can lead to more significant engine damage down the line. Regular maintenance, such as using high-quality fuel and replacing the fuel filter at the recommended intervals, can help prevent fuel injector issues. Also, keep an eye out for any unusual noises coming from the engine bay or any signs of fuel leaks.

Finally, some owners have reported issues with the turbocharger. While the turbocharger on the 1.8 DI-D engine is generally robust, it can fail over time, especially if the engine isn't properly maintained. Symptoms of a failing turbocharger can include a loss of power, unusual noises like a whistling sound, and excessive smoke from the exhaust. If you suspect a turbocharger problem, get it checked immediately. Replacing a turbocharger can be expensive, so it's essential to catch the problem early. Regular oil changes with the correct type of oil, as specified in your owner's manual, are crucial for turbocharger longevity. Also, avoid revving the engine hard immediately after starting it, as this can put extra stress on the turbocharger.

Transmission and Drivetrain: Power Delivery Problems

Moving on to the transmission and drivetrain, the 2011 Mitsubishi ASX 1.8 DI-D 4x4 features a manual transmission, which generally is pretty reliable. However, some owners have reported issues with the clutch. Over time, the clutch can wear out, leading to problems like slipping or difficulty shifting gears. Clutch wear is a natural part of a car's life, and the lifespan of a clutch depends on driving habits. If you experience clutch problems, you'll need to have the clutch replaced. This is a relatively expensive repair, but it's necessary to ensure the car's drivability. To extend the life of your clutch, avoid riding the clutch pedal and try to shift smoothly.

For the 4x4 system, some owners have reported issues with the electronic control unit (ECU). The ECU manages the all-wheel-drive system, and if it malfunctions, it can cause problems with the engagement and disengagement of the 4x4. If you experience issues with the 4x4 system, it's best to have it diagnosed by a mechanic with experience in Mitsubishi vehicles. They can run diagnostic tests to pinpoint the problem and determine the appropriate repair. The 4x4 system is a significant selling point of the ASX, so it's essential to keep it in good working order, especially if you live in an area with challenging weather conditions.

Another potential issue related to the drivetrain is driveshaft problems. While not as common as some other issues, driveshaft problems can cause vibrations and noises, especially at higher speeds. If you notice any unusual vibrations or noises, get the driveshafts inspected by a mechanic. They can check for wear and tear and replace the driveshafts if necessary. Regular inspection of the driveshafts and other drivetrain components as part of your routine maintenance can help prevent problems.

Suspension and Steering: Ride and Handling Issues

The suspension and steering systems contribute significantly to a car's ride and handling. The 2011 Mitsubishi ASX is generally known for its comfortable ride, but like any car, it can develop issues over time. One common problem is with the suspension components. Over time, shocks and struts can wear out, leading to a bouncy ride or reduced handling performance. If you notice these symptoms, it's time to have your shocks and struts inspected and possibly replaced. Replacing worn suspension components can significantly improve the ride quality and handling of your ASX. Additionally, check for any leaks from the shocks or struts, as this can be a sign of wear.

Another area to keep an eye on is the steering system. Problems with the power steering pump or other steering components can lead to issues like difficulty steering or unusual noises when turning the steering wheel. If you experience any of these problems, get the steering system checked by a mechanic. They can diagnose the problem and perform the necessary repairs. Regular maintenance, such as checking and topping up the power steering fluid, can help prevent steering problems. Also, watch out for any leaks from the power steering system.

Furthermore, some owners have reported issues with the wheel alignment. Hitting potholes or driving over rough roads can cause the wheel alignment to go out of adjustment, leading to uneven tire wear and reduced handling performance. It's a good idea to have your wheel alignment checked regularly, especially if you notice any unusual tire wear or steering problems. A wheel alignment is a relatively inexpensive service that can help extend the life of your tires and improve your car's handling. Consider getting your alignment checked every year or every 10,000 miles.

Electrical System: Gadget Glitches

Modern cars are full of electronic components, and the 2011 Mitsubishi ASX is no exception. While the electrical system is generally reliable, some problems can occur. One common issue is with the battery. Batteries can fail over time, especially in cold weather. If your car is slow to start or won't start at all, the battery is likely the culprit. You can have the battery tested at most auto parts stores to determine if it needs to be replaced. Replacing a battery is a relatively straightforward process. To help prolong the life of your battery, avoid leaving electrical accessories on when the engine isn't running, and make sure to have the battery terminals clean and corrosion-free.

Another potential electrical issue is with the alternator. The alternator is responsible for charging the battery while the engine is running. If the alternator fails, the battery will eventually die, and the car will stall. If you suspect an alternator problem, get it checked by a mechanic. They can test the alternator and replace it if necessary. Symptoms of a failing alternator can include dimming headlights, a flickering dashboard, and a battery warning light on the dashboard.

Furthermore, some owners have reported issues with the infotainment system. The infotainment system in the ASX controls features like the radio, navigation, and Bluetooth connectivity. If the infotainment system malfunctions, it can be frustrating. Problems can range from the system freezing up to losing functionality altogether.
