Q: BMW X6 N55 engine, throttle cleaning was done in the repair shop, now the fault light is on, reporting the fault code “2A80”, how should it be solved?
A: You can unplug the charcoal canister solenoid valve plug, then drive the car out for half an hour, return to the shop to do a match, and then restore it. If the fault code still cannot be cleared, it is necessary to focus on checking whether there are other fault codes for mixture imbalance. You may as well use a cloth ball to block the air intake at idle speed and observe whether the engine can be turned off. If it does not turn off, you need to check whether the intake manifold is leaking. In addition, carbon deposit pollution will also cause this fault code, which can generally be solved by cleaning the intake duct and the three-way catalytic converter.
