I am having the same issue, ONLY when i turn right, 2 clunks, noticeable at lower speeds with loaded suspension (i lifted the car to turn the wheel and check - no knocking), I feel it slightly at my feet and in the steering wheel. Has been slowly getting worse.
I had the exact same problem on my 2008 535i. After much troubleshooting by my independent, he eventually found that the active sway bar had been damaged when I hit a dip in the road under full braking. He replaced it...apparently it requires some kind of calibration/programming...he did that, and problem was fixed. I bet this is what is your problem. Mine ONLY made the noise when I turned LEFT under load. You may want to have your active sway bar checked.....if all mechanical stuff looks ok.
@Allen I've been having a feeling that this is the issue since i feel it in the steering wheel and at my feet. I'm hoping to get it checked out next week. Maybe, since I did do my own water pump, its just a loose bolt down there.
No chance i'm going to be spending that kind of money. Not on a sway bar. There's a reason i'm even holding off on replacing the turbos. in the last year I've don't 4 front control arms, stabilizer links, water pump thermostat. the year before was valve cover, belt tensioner and pulleys, oil filter, oil cooler gaskets. Even if i try to sell the car today. Id be blessed to get 6k for it. Im still on index 1 injectors and theres a log list of things that can still go wrong
but yet I still love this car.

I'm sure you've heard the phrase..."you're telling Noah about the flood..."? I too have spent way too much on mine. But I am the original owner, the interior and body are literally like new....and I LOVE this car. It would take a TON of money to get another car that could fill it's shoes. So, it's the age old car delima...how many repairs could a $500 per month car payment make?
Honestly, I can't see a scenario where I scrap this car due to repair costs. I did the exact same with my '95 525i...but it required very minimal money over it's 256,000 miles. I only got rid of it when I was rear-ended and it was totaled...a VERY VERY sad day that was!!

i have NO plans to scrap this car. its too nice and comfortable and relatively fuel efficient also. Eveutually i have to get the oil pan done. In fact im picking up mtech bumpers/skirts and paddle wheel/ sat shifter tomorrow lol. i cant help myself.
I will update everyone on my outcome with the noises. Im actually starting to think it may be a strut mount also as it only happens under loaded suspension.
So I think the problem was a fatiguing subframe mount for the anti roll bar. A year after the problem started, the bolting point for the anti roll bar clamp sheared off the frame which required a front subframe replacement. Since the subframe is made of aluminum, it is more likely to experience failure from fatigue. I'm guessing the sound was from the metal slightly bending during each turn and loading of the bar.
I know it’s been a while but how did your subframe anti roll bar mounting bracket got fixed? Was it welded back or have to replace the whole subframe? I have the exact same issue😕

might be able to get it welded, but most mechanics won't do that and recommend a subframe replacement. I had to replace the subframe. If you catch it early you might be able to get it welded to prevent it from breaking. The issue with aluminum is that once it cracks, it will continue to grow as the part is loaded and unloaded.
