How often does the BMW 5 Series throttle have to be cleaned?

It is generally recommended that car owners clean the throttle every 20,000-40,000 kilometers, and the specific cleaning cycle depends on personal car habits and car environment. Throttle is a controllable valve, which controls air to enter the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work.

Problems needing attention in cleaning BMW 5 Series throttle;

If there is too much sludge in the throttle, it may cause poor engine acceleration and increase fuel consumption, which is a big worry for the owner. What if the throttle is dirty? Wipe it clean. Go to the 4S shop, and it will be finished soon, but don't you go to the 4S shop every time? Actually, you don't have to. You can do it yourself. Just don't forget to initialize.

First, apply a little oil on the fixed metal circlip to prevent the teeth from slipping during disassembly. Remove the metal wire harness ring of the throttle hose. After the hose is removed, the left end is the position of the throttle. Remove the negative battery, turn off the ignition switch, straighten the throttle, spray a small amount of "carburetor cleaner" into the throttle, and then carefully scrub it with a polyester rag or a high-count "non-woven fabric". Deep in the throttle valve, where the hand can't reach, take a rag and scrub it carefully.

When cleaning the throttle valve, it is not necessary to disassemble it, but it is necessary to clean the sealing part of the inlet steam. Idling motor must be removed before cleaning. Cleaning the nozzle and avoiding disassembly have their own advantages and disadvantages. Generally speaking, the maintenance station suggests avoiding disassembly and cleaning to prevent other unnecessary waste, such as replacing the sealing ring or installing other gaskets after disassembly, or leaking oil and gas during disassembly and assembly, which will delay the owner's time.
