What are the common issues with the Ford S-Max turbocharger?

I recently purchased a Ford S-Max and have been experiencing some issues with the turbocharger. It seems to be making strange noises and losing power. What could be causing this and what steps should I take to resolve it?

It is possible that there could be a leak in the intercooler pipes, which can cause strange noises and a decrease in power. It's best to have a mechanic check for any leaks and replace any damaged pipes.

Another common issue with the Ford S-Max turbocharger is carbon buildup on the turbo vanes. This can be solved by using a specialized cleaning solution and regularly driving at higher speeds to prevent buildup.

If the turbocharger is making a knocking sound, it could be a sign of a failing bearing. In this case, it's important to have the turbocharger replaced by a professional as soon as possible to avoid further damage to the engine.
