Hi .

This is a problem i've seen a few times ,from the tremor in steering wheel at 40 mph and under hard braking is a possible wheel bearing failure which will but the wheel speed sensor off spec and trip your ABS and Limited slip light ON ,

The BMW ABS system can have a hard time being read fron None BMW approved scan tools ,i suggest you have the system read by an approved tool to see where the problem is .

Check the front end steering, and wheel bearings if you find that one of the bearings are lose then this is where your problem is..

Need further assistance with this issue then please get back to me if needed.
