Flashing DSC and computer causing braking at highway speeds: What could be wrong?

[S18adeli]

I have a 2002 X5 4.6is with around 108k miles and for some time now since I took the car to the shop to change the wheel bearings I have this odd problem that I cant figure out. I changed the front wheel speed sensors but problem still persists.

When driving around 40-50mph or 65-80mph (mostly) on the freeway, the DSC light will flash and traction control will kick in. This usually happens when driving more uphill with some throttle. The computer thinks the car is slipping and cuts power or applies the brakes. When I turn DSC off, the computer will actually apply the brakes to either front side causing the car to slow down for a half second.

After running a scan, the following codes popped up:

-BD | Electronic Brake Balance (EBV)
-97 | Steering Angel Adjustment Faulty
-And some others but it think these could be the only relevant ones.

Any thoughts on what it could be?

I had similar problems but at slow speeds when one of my sensors was loose. You said you replaced them I'm wondering if they didn't seat all the way in they are pretty finicky that way.

The steering angle code is worth checking. Did you go through the lock to lock reset procedure? See if that code won't clear you may have a faulty steering angle sensor

When my steering wheel was out of center from some front end work I did the brakes were kicking in on their own and the dsc light was going nuts on my e46.

I had an alignment done and reset all adaptations and problem persists.
