Prep the car: pull out the fuel pump fuse, open the gas cap, and let the car cool down
When preparing to clean the fuel injectors on your 2000 C230 Kompressor, there are a few important steps to take to ensure your safety and make the process more effective. Firstly, locate and remove the fuel pump fuse, which will shut off the fuel pump. This is an essential step as it prevents the engine from running on gasoline during the cleaning process, reducing the risk of fire or explosion.
Next, open the gas cap. This is done to depressurize the fuel system. By opening the gas cap, you allow the pressure to escape, making it safer to work on the fuel injectors. It is crucial to perform this step after removing the fuel pump fuse, as the order of these steps is vital for safety reasons.
Additionally, it is important to let the car cool down before beginning any cleaning or maintenance work on the fuel injectors. Allowing the engine to cool ensures that you can work safely without risking injury from hot engine components. A cool engine also makes it easier to handle and manipulate various parts during the cleaning process. It is recommended to park your vehicle in a well-ventilated area, away from direct sunlight or any open flames, to ensure optimal safety conditions.
Before proceeding with the cleaning process, make sure to disconnect the fuel pump from the fuel injectors and disconnect the pressure regulator vacuum line. These steps are crucial for your safety and for effectively cleaning the fuel injectors. By following these preparatory steps, you can help ensure a smoother and safer cleaning experience.

Have safety equipment: a fire extinguisher, chemical-resistant gloves, and rags
When cleaning the fuel injectors on your 2000 C230 Kompressor, it is important to have the necessary safety equipment. This includes a fire extinguisher, chemical-resistant gloves, and rags.
A fire extinguisher is crucial due to the highly flammable nature of petrol. Petrol vapours can easily ignite, and a fire extinguisher will help you quickly suppress any flames that may arise during the cleaning process. It is important to have a fire extinguisher nearby and easily accessible throughout the entire procedure.
Chemical-resistant gloves are essential to protect your hands from the hazardous chemicals and detergents used in the cleaning process. These gloves will act as a barrier between your skin and the harsh substances, ensuring your safety and preventing any skin irritation or damage.
Rags, or absorbent cloths, are also necessary for safety and cleanliness. They can be used to wipe up any spilled fluids, such as gasoline or cleaning solutions. Keeping the work area clean and free of spills is important to prevent accidents and ensure a smooth workflow.
In addition to these essential safety items, it is also advisable to wear protective clothing, such as long sleeves and pants, to cover your skin and protect yourself from any chemical splashes. Safety goggles are also recommended to protect your eyes from any debris or chemicals.
By having the necessary safety equipment, you can help ensure that the fuel injector cleaning process is carried out safely and effectively, reducing the risk of accidents and potential harm to yourself and your vehicle.

Perform the injector removal in a well-ventilated area
When performing injector removal, it is important to choose a suitable location. Opt for a clear, open, and well-ventilated space. This is crucial not only for your comfort but also for safety reasons. Working in a well-ventilated area helps to mitigate the risks associated with gasoline fumes.
Before beginning the removal process, ensure you have properly prepped the car. Start by pulling out the fuse for the fuel pump and then attempt to start the car. It will turn over and then die. Repeat this step a few times to drain excess fuel from the system. Additionally, open the gas cap to aid in depressurizing the system. Allow the car to cool down before proceeding. Working on a hot car can be dangerous, especially when dealing with gasoline.
Have a fire extinguisher readily available as there will likely be some fuel spillage during the removal process. This is a nearly unavoidable aspect of the procedure, so it is important to be prepared. Wear chemical-resistant gloves to protect your hands from gasoline, and have plenty of paper towels or rags on hand for cleanup.
It is also recommended to have an assistant nearby in case any problems arise. This can provide added peace of mind and ensure that you are not alone should any complications or challenges arise during the injector removal process.

Remove the fuel filter: place the car on jack stands, remove the screws, and clamps
To remove the fuel filter from your 2000 C230 Kompressor, you will need to place the car on 3-ton jack stands for your personal safety. The fuel filter is located at the rear right of the car, between the drive shaft and the rear tire. It is covered by a black, plastic cover guard.
To access the fuel filter, you will need to remove the screws holding the cover guard in place. There should be three screws that need to be removed. Once the screws are removed, you can take off the cover guard and access the fuel filter.
The fuel filter is held in place by a metal bracket, and the hoses are clamped onto the filter with "permanent" crimp-style clamps. These clamps will need to be removed as well. Be cautious, as the fuel filter is pressurized, and gasoline will start to drip once you remove the fuel line.
To remove the fuel filter, you will also need to remove the Phillips screw holding it in place. After removing the screw, you can carefully take out the fuel filter. Remember to have a fire extinguisher nearby and wear chemical-resistant gloves to protect your hands from gasoline.

Clean the injectors: use a bottle to feed fuel to the engine through the intake
To clean the injectors on your 2000 C230 Kompressor, you can try using a bottle to feed fuel to the engine through the intake. This method can help flush out any built-up carbon, gunk, or impurities that may be clogging the injectors and affecting the engine's performance. Here's a step-by-step guide on how to do it:
Step 1: Prepare the Vehicle
Park your car on a level surface and engage the parking brake. Put on gloves and safety glasses for protection. Locate the fuel injectors and identify the intake side, which is where you will feed the fuel. Refer to your car's repair manual for specific locations and procedures.
Step 2: Disconnect Components
Disconnect any necessary components to access the fuel injectors, such as hoses or electrical connections. Be careful when handling sensitive parts and consult a mechanic or a repair manual if you are unsure.
Step 3: Feed Fuel Through Intake
Using a bottle, carefully pour a small amount of fuel into the intake side of the fuel injectors. Ensure that the fuel is clean and free of contaminants. You can also use a fuel injector cleaner fluid for better results.
Step 4: Crank the Engine
With the fuel in the intake, try to start the engine. It may take a few attempts, but cranking the engine will help draw the fuel through the injectors and flush out any built-up debris.
Step 5: Observe and Adjust
Pay attention to the engine's performance during cranking. You may need to adjust the throttle or air intake settings to ensure the engine gets enough fuel for the cleaning process.
Step 6: Repeat as Needed
If the injectors are severely clogged, you may need to repeat the process several times. Each time, use fresh fuel or cleaner fluid and ensure that the intake and injectors are free of debris.
Step 7: Reassemble and Test Drive
Once you've completed the cleaning process and are satisfied with the results, carefully reassemble any disconnected components. Take the car for a test drive to evaluate the engine's performance and ensure that the cleaning has improved the fuel injection system.
Remember to exercise caution when working on your vehicle, and if you feel uncomfortable with any part of the process, consult a professional mechanic or a trusted car enthusiast.
