Welcome to the forum. You have posted your question in the area of the forum where people who are having issues with the forum itself are supposed to pose question. If you are having problems with your vehicle, you should post your question in the appropriate vehicle area of the forum. That's where owners of similar vehicle hang out
When you post a question, provide as much information about the vehicle and the problem as you can. Things like the make, model and year of the car, the engine size and mileage. Set out the history of the problem, what, if anything, caused it in the first place, what you might have done to try to fix it, what sort of service history the car has, and any other information that might bear on the problem.
"Strange noises", even with a recording, are very difficult, if not impossible to diagnose over the internet. At least give an indication of where, exactly on the car, the noise id coming from. Recordings are not at all helpful to determine that.

Good luck.
