Active solvent with highly effective additive combination. Eliminates contamination and deposits in the diesel intake and throttle valve area. Loosens and removes contamination such as oil, resin, soot, etc. Ensures the operability of all moving parts and increases the operational reliability of diesel engines.


For cleaning the intake manifold and intake valves. Recommended for preventive use during the inspection. Only suitable for use in diesel engines.


Applic­a­tion

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 revolutions 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. Do not remove the spray head from the can again after assembly. After use, allow the engine to run for about 20 seconds at min. 2,000 revolutions in order to burn any residues remaining in the intake system.

Other inform­a­tion

Do not remove the spray head from the can again after assembly.

Fit 2015 228xi even tho not exact shape as oem
The large clip that has the feet that point out in second position(ballet term, google it so you see what the orientation looks like) fits with much more ease than you’ll think. It won’t hook into its oem place but the top flat squared off part will hook to the interior roof of the that general area snuggly. Spent 1.5 hours trying to bend the smaller ones into a similar shape to oem and then it hit me. The bigger one would probably be large enough to catch the top of the bulb housing. Learn from me. Try the big one.
