BMW maintenance after driving over 60000 kilometers, engine malfunction light on

A BMW entered the store and the owner said that there was a yellow fault light on the dashboard, which had been on for several days and had not affected anything. This time, if you have time, come and see where the problem is.

As shown in the figure below, the yellow small light in the right corner of the instrument panel is the fault light. The shape of the engine has a total mileage of over 60000 kilometers. For such faulty lights, a computer must be connected to identify the problem.

After connecting to the computer, the mechanic quickly identified the root cause of the problem, which was an abnormal function of the fuel tank exhaust system. For such fault prompts, the mechanic determined that it was a problem with the carbon canister solenoid valve. After inspection, it was confirmed that it was a problem with the solenoid valve, and other components would not cause such problems.

If there is a problem with the carbon canister solenoid valve, simply replace it with a new component. It seems that there is no other way to repair this solenoid valve. As shown in the figure below, this is a new carbon canister solenoid valve that has not been disassembled yet.

After the installation of the new carbon canister solenoid valve, the mechanic deleted the old fault code on the computer and retested that there were no more fault codes. The yellow fault light on the instrument panel also disappeared.
