How to clean the BMW 1 series throttle and how to clean the BMW 1 series throttle.

How to clean the accelerator of BMW 1 series; First of all, if there is a plastic heat shield on the engine, it needs to be removed first. When the hood is removed, we can usually see the throttle. Some air pipes are connected around the throttle valve. We need to dismantle these pipes and remember the location of each pipe. After the air pipe on the throttle is removed, we can remove the whole throttle. Trent's throttle is fixed on the engine block with four bolts, and we can quickly remove it with suitable tools. The side of the throttle near the combustion chamber is usually dirty, and the black carbon trace is the main part that needs cleaning. Cleaning the throttle is mainly to remove carbon deposits on it. We can use special throttling cleaning liquid or detergent. It should be noted here that the cleaning principle of this cleaning agent is to dissolve carbon deposit, and its composition is harmful to human body. It is best to wear gloves and masks when cleaning. Spray the cleaning agent to the position with more carbon deposits on the throttle, and wait for the carbon deposits to dissolve for about 5- 10 minutes. Brushes can speed up the removal of carbon deposits. When we see that the stain on the accelerator has completely dissolved, we can wipe the detergent inside the accelerator with a clean towel. The picture above shows the clean back of the throttle valve, and there is no trace of carbon deposition at all. Install the cleaned throttle valve on the engine block according to the original position, and then install all the air pipes to complete the whole process of cleaning the throttle valve. After all the hardware is installed, we need to initialize throttle.
