Why is my Vauxhall Grandland emitting black smoke?

I recently noticed that my Vauxhall Grandland is emitting black smoke from the exhaust. What could be causing this and how can I fix it?

Black smoke from the exhaust is a sign of an overly rich fuel mixture. This can be caused by a variety of issues such as dirty air filters, faulty oxygen sensors, or even a clogged catalytic converter.

I recommend taking your Grandland to a trusted mechanic for a diagnostic test. They will be able to pinpoint the exact cause and provide a solution. In the meantime, try replacing your air filter and see if that helps.

Another common cause of black smoke is a faulty fuel injector. This can be diagnosed and fixed by a mechanic. It's important to address this issue as it can lead to decreased fuel efficiency and engine performance.
