What Are Common Issues with the Vauxhall Vivaro's Engine?

I've been having some trouble with my Vauxhall Vivaro's engine and I'm not sure what the root cause could be. It seems to be running rough and I'm worried it might be something serious. What are some common problems that could be causing this issue?

One common issue with the Vauxhall Vivaro is a faulty EGR valve. This can cause rough engine running and reduced performance. I would recommend having this checked and possibly replaced by a trusted mechanic.

Another potential issue is a dirty or clogged fuel filter. This can lead to reduced fuel flow and cause the engine to run rough. It's a relatively inexpensive and easy fix, so I would recommend having it checked and replaced if necessary.

If your Vauxhall Vivaro is a diesel engine, you may also want to check the glow plugs. Faulty or worn glow plugs can cause difficult starting and rough engine running. I would recommend having these checked and replaced if needed.
