For cleaning the intake manifold and intake valves. Recommended for preventive use during the inspection. Suitable for vehicles with EGR (exhaust gas recirculation) valve and DPF (diesel particulate filter). Only suitable for use in diesel engines.
Shelf life in original sealed container: 24 months
Create access to the intake system. This should be positioned downstream of the air flow meter/turbocharger/charge air cooler, where possible directly in front of the intake manifold. Start the engine to begin cleaning.
If the engine cannot maintain the speed with the intake pipe removed or cannot be started, disconnect the plug from the air flow meter with the ignition switched off. In this case, the stored fault must be deleted from the engine control unit after cleaning using a suitable diagnostic device and the air flow meter must be taught in again if necessary.
Spray the Diesel Intake System Cleaner into the intake system via the spray probe in short intervals of 2–3 seconds at min. 2,000 revolutions. Move the probe back and forth in the process to clean the entire intake tract.
If a speed increase of more than 1,000 revs occurs during application, it is important to stop the spraying process immediately. Make sure that the Diesel Intake System Cleaner does not come into contact with the air flow meter or with painted components.
In the case of stubborn deposits in the intake manifold or on the intake valves, cleaning can be repeated with a second can. After use, allow the engine to run for about 20 seconds at min. 2,000 revs in order to burn any residues remaining in the intake system.
Do not remove the spray head from the can again after assembly!
