BMWX1What should I do if the throttle valve is dirty? Just clean it. You can get it done quickly by going to the 4S store, but don’t you have to go to the 4S store every time for cleaning? Actually, no, you can do it yourself, just don’t forget to initialize it.
First, put a little oil on the fixed metal ring to prevent the teeth from slipping during disassembly. Remove the metal bundle ring of the throttle hose. After removing the hose, the left end is where the throttle valve is. Remove the negative electrode of the battery, turn off the ignition switch, straighten the throttle flap, and spray a small amount of "carburet" into the throttle valve. Then use a polyester rag or high-woven "non-woven fabric" to carefully scrub. Deep inside the throttle and out of reach, you can use a clip to hold the rag and scrub carefully.
It is not necessary to disassemble the throttle when cleaning, but the sealing part of the steam inlet must be cleaned. The idle motor must be disassembled before it can be cleaned. There are advantages and disadvantages to disassembling the injector for cleaning or eliminating the need for disassembly. Under normal circumstances, the maintenance station recommends that it does not require disassembly. Disassemble and wash to prevent other unnecessary waste, such as the need to replace the sealing ring or the installation of other gaskets after disassembly, or oil leakage, gas leakage, etc. during the disassembly and assembly process, which delays the car owner's time.
After cleaning, follow the disassembly procedure just now. After installation, you must start initializing the throttle.

After cleaning, follow the disassembly procedure just now. After installation, you must start initializing the throttle. After cleaning the throttle, initialization is necessary because when the computer adjusts the throttle opening, it has a memory function. If there is a sludge blockage, in order to ensure the air intake, the computer will automatically adjust the throttle opening to keep the air intake in a normal state.
After cleaning, if there is no sludge clogging, if the throttle still maintains the previous opening, it will cause the air intake to be too large. The consequences will be that the engine shakes when starting, the acceleration is weak, and the engine fault light may also come on. Bright.
So why can the engine sometimes work normally without initialization after cleaning the throttle? That's because the throttle isn't too dirty, and its air intake hasn't changed much after cleaning. However, the changes in the throttle after cleaning cannot be observed with the naked eye, so initialization should be done.
In fact, initialization is very simple. It can be done with a dedicated computer, or it can be done manually, but it is not as fast as a computer, and sometimes it will fail. It doesn't matter if it fails, just do it again. There are two ways to do initialization depending on the car:
BMW X1 initial method:
The first is to turn the key in the second gear, which is the gear where the instrument indicator is fully lit, then wait for 20 seconds, step on the accelerator to the bottom, hold it for about 10 seconds, release the accelerator, turn off the ignition switch, pull out the key, and initialize. finished.
The second is to turn the key in second gear, hold it for 30 seconds, then turn off the ignition switch and pull out the key.It should be noted that after completing both methods, you have to wait for a period of time before you can try to ignite. Generally, wait 15-20 seconds, then ignite and see if the refueling is normal and whether the engine fault light goes out. If not oncesuccessjust do it a second time until you succeed. Generally, you can succeed once, at most twice.
