Fuel consumption of BMW 325 10 after washing the throttle

10 The fuel consumption of BMW 325 after washing the throttle is 12 liters/100 kilometers. Generally, the computer needs to be reset after the throttle valve of the EFI vehicle is cleaned. If you don't do it, it is likely to cause a big increase in fuel consumption.

Generally speaking, the simplest reset method is to disconnect the battery cable for more than 30 seconds. I suggest you disconnect 1 min, then reconnect and run again. However, some models cannot be reset in this way, and they must be connected to the maintenance computer through the on-board OBD interface. In this case, you can only go to the 4S shop or garage to repair the computer.

The reason of high fuel consumption after cleaning the throttle: Because the cleaned throttle must be matched with the computer again, the normal operation of the engine can be guaranteed after the matching is completed, and the phenomenon of increasing fuel consumption and increasing speed after cleaning the throttle will disappear.

Because the throttle has not been cleaned for a long time, the position of the throttle and throttle arm is worn too much. At this time, after the throttle valve is cleaned, the clearance is larger, so the fuel consumption will become higher.

After cleaning the throttle valve, the relevant matching treatment was not done, which led to the computer detection program still adjusting the fuel injection quantity according to the original throttle valve calculation. Under normal circumstances, the car will gradually adapt after driving for a period of time, and the fuel consumption will return to normal.
