Troubleshooting Issues with the Vauxhall Vivaro's Engine

I am experiencing problems with my Vauxhall Vivaro's engine, such as losing power and strange noises. What could be causing this and what steps should I take to troubleshoot?

It is possible that there could be an issue with your fuel injectors. I would recommend getting them checked and replaced if necessary.

Another common problem with the Vauxhall Vivaro's engine is a faulty EGR valve. This can cause similar symptoms to what you are experiencing. I suggest getting it inspected and replaced if needed.

Before taking any drastic measures, make sure to check the basics such as oil and coolant levels. Low levels can also cause these issues.

If the issue persists, it could be a problem with the air flow sensor. This can be easily replaced, but it is recommended to get it diagnosed by a professional mechanic.
