What are the most common technical issues in Vauxhall Insignia vehicles?

I have a 2015 Vauxhall Insignia and have been experiencing some problems with the engine. It's running rough and I can hear strange noises. What could be causing these issues?

Based on your description, it sounds like you may have a faulty ignition coil. This is a common issue in Vauxhall Insignia vehicles and can cause rough engine running and strange noises. It's important to get this checked and replaced by a professional mechanic as soon as possible to avoid further damage.

Another possible cause for these issues could be a clogged fuel filter. This can restrict the flow of fuel to the engine, causing it to run rough and make strange noises. I recommend getting the fuel filter replaced and also having the fuel injectors cleaned to prevent future problems.

One more thing to check is the spark plugs. If they are worn out or dirty, it can also cause the engine to run rough and make strange noises. I suggest getting the spark plugs inspected and replaced as needed.
