Power loss and turbine noise on BMW X2

Good morning everyone, I own a 2018 BMW X2 M Sport 18d diesel. Recently, the check engine light came on accompanied by a loss of power, allowing me to proceed only at moderate speed. Additionally, I noticed an unsettling noise coming from the turbocharger. This problem occurred while driving uphill with the air conditioning on. Turning off the engine and the air conditioning, the problem disappeared after about a minute. Two months ago, the turbo pressure sensor was replaced because it was faulty. Has anyone had similar experiences or knows what could be causing this problem? Thanks in advance for your help!

A 2018 BMW X2 M Sport 18d diesel experienced a check engine light, power loss, and unusual turbocharger noise while driving uphill with the air conditioning on. The issue resolved temporarily after turning off the engine and air conditioning. A previously replaced turbo pressure sensor might not be the root cause. Suggested solutions include checking for leaks or loose fittings in the turbocharger hoses and inspecting the turbocharger for damage, with a recommendation to consult a professional mechanic if the problem continues.

I recommend starting by checking the turbocharger hoses and connections for any leaks or loose fittings, as these can cause a loss of power and unusual noises. If everything seems intact, it might be worth inspecting the turbocharger itself for any signs of damage or wear. Given the safety implications of a malfunctioning turbocharger, it would be wise to have a professional mechanic take a look if the issue persists. Let me know how it goes or if you have any further questions!
