How to troubleshoot a faulty engine in a Vauxhall Movano?

My Vauxhall Movano has been experiencing issues with its engine, it seems to be struggling and making strange noises. What steps can I take to diagnose and fix the problem?

The first step is to check the engine oil and make sure it is at the correct level. Low oil can cause engine issues.

Next, I recommend checking the spark plugs and replacing them if necessary. Old or faulty spark plugs can affect engine performance.

If the issue persists, it could be a problem with the fuel system. Check the fuel filter and fuel pump for any clogs or malfunctions.
