Ticking and whining noise 525d
Hello, the car is 525d 2004 e60 with 98k miles.
Last week on cold starts the car has a tapping noise that goes with the revs until 1500rpms also a whine that is definitely more audible with the ac turned on cold.
Less pronounced with it off. And also the tapping I believe is less audible when warm.
I was told by the seller that the dpf is gutted.
Also sometimes it has a hiccup just below 2k rpm when stepping on it. The power is still there as it used to be.
Anyway I wanted to hear some insights from you guys!

I have a bm700 obd reader and two codes have popped up :
4166 particulate filter system
A6a6 coding data fault
I was told by a mechanic here that it's the power steering pump and to not worry. Just don't feel like leaving it until something breaks and leaves me stranded.4166 particulate filter system

Well, the seller told you about the DPF, and you have the code for that. That can cause a host of issues.
Lots of things can cause that ticking / whining. Did you take it to a seasoned BMW specialist?
