Thanks for the reply. I haven't checked the boost pipes myself, I don't really know how. Where are the pressure sensors located? Is it something I can easily check, or should I take it to a mechanic?

If you aren't sure, best take it to a workshop. I ended up having a defect in the wastegate valve, and that was causing all sorts of grief. The pressure sensors are usually near the throttle body or on the intake manifold. But without the right tools, diagnosing it yourself might be tricky.

Thanks for the advice! Took it to the shop and it was indeed a wastegate valve issue. Cost 860€ to repair. Appreciate the help!

I had similar issues with my Focus. Have you checked for any leaks in the boost pipes? When mine went, it caused all sorts of problems with boost control and made a weird whistling sound. Could also be a faulty pressure sensor. Does it feel like turbo lag?
