Dear Robert,

I noticed some black smoke coming from my 2019 Nissan Sentraâ€™s exhaust yesterday and heard what sounded like a popping noise. My friend said this could be down to a dirty air filter: is he right?

Thanks,
Mathew

Hi, Mathew!

There are a number of things that could cause black smoke to come from your 2019 Nissan Sentraâ€™s exhaust. But your friend is correct that a dirty air filter may be the culprit.

Your air filter ensures that the right amount of oxygen reaches the engine. When it gets too dirty not enough air is let in.

If your Sentraâ€™s engine isnâ€™t getting enough oxygen, it might not burn off fuel at an adequate rate. This could result in some gasoline running through the carâ€™s system which would cause black smoke.

As the unburnt fuel runs through your vehicleâ€™s system it becomes super-heated, this results in the popping sounds you have been hearing.

When you waste fuel like this your carâ€™s mpg will drop and itâ€™s also bad for the environment. I think you should call down to our Service Department and let the Technicians have a look.

Thanks for your question, Mathew! Contact Kirkland Nissan, Washington if you need anything else.
