What are the symptoms of a faulty turbocharger in a Vauxhall Insignia?

I have been experiencing a lack of power and weird noises coming from my engine in my Vauxhall Insignia. I suspect it could be a problem with the turbocharger. Can anyone confirm what other symptoms could point to a faulty turbocharger?

If your turbocharger is faulty, you may also notice a decrease in fuel efficiency and an increase in smoke coming from your exhaust.

I had a similar issue with my Insignia and it turned out to be a faulty turbocharger. Get it checked as soon as possible to avoid further damage.

Unusual sounds coming from the engine and a decrease in overall performance are both common signs of a faulty turbocharger. It's worth getting it checked by a professional.
