How to troubleshoot engine issues in a Vauxhall Crossland?

I've been experiencing some problems with my Vauxhall Crossland's engine. It's been making strange noises and I've noticed a decrease in performance. What could be causing this and what steps should I take to fix it?

It's important to first check your oil levels and ensure they are at the recommended level. Low oil levels can cause engine issues and should be topped up if necessary. Also, check for any visible leaks under the car as this could indicate a bigger problem. If everything seems fine, it's best to take your car to a certified mechanic for a diagnostic test.

Another common issue that could cause engine problems is a faulty spark plug. Over time, they can wear out and should be replaced to maintain optimal performance. It's a simple fix but can make a big difference. If you're not comfortable replacing them yourself, consult a mechanic.

If your Crossland is equipped with a turbocharger, be sure to regularly check the air filter. A dirty or clogged air filter can reduce air flow to the engine and affect its performance. It's an easy fix that can prevent future issues with your engine.
