It's possible, but sounds more like a caliper that is sticking and not because of the pins.
...bmw recommends to clean and get rid of any brake dust buildup, but not to grease. Like my above post, I put a small amount of high heat, rubber friendly grease on my rear pins and have no problems. I am doing my fronts soon and prob won't grease the pins though.... Even though the right kind and small amount of grease can't hurt...
