How to troubleshoot engine issues in my Vauxhall Movano?

I am facing some engine issues in my Vauxhall Movano and need advice on how to troubleshoot them. The engine is making strange noises and the performance seems to be affected. What could be the possible reasons and how can I fix them?

The strange noises could be due to a faulty spark plug or a clogged air filter. It is recommended to check and replace these components if necessary.

Low engine oil level or dirty oil can also cause engine issues. Make sure to check the oil level and change it if it is dirty.

If none of the above seems to be the issue, it could be a problem with the fuel injectors. It is advisable to take your Vauxhall Movano to a certified mechanic for further diagnosis and repair.
