When the check engine light comes on in a Nissan Qashqai, it can indicate a variety of issues. Some possible causes include:
* A loose gas cap
* A faulty oxygen sensor
* A problem with the catalytic converter
* A transmission issue
* An engine problem
Warning Light
If a warning light other than the check engine light comes on, it may be more urgent to address. Warning lights may include:
* The oil light indicates low oil pressure. This can be caused by a low oil level or a problem with the oil pump.
* The coolant light indicates low coolant levels. If you see this light, stop driving and check the coolant level. If it is low, add coolant and continue driving. However, if the coolant light continues to come on, there may be a problem with the cooling system.
* The battery light indicates a problem with the charging system. If this light comes on, take your car to a mechanic as soon as possible.
* The brake light indicates a problem with the brake system. If this light comes on, take your car to a mechanic immediately.
If the Warning Light Won't Go Off
If the warning light won't go off after addressing the immediate issue (eg adding coolant), it is important to take your car to a mechanic as soon as possible. Ignoring warning lights can lead to serious problems with your car.
