I bought a BMW 135i n55 with 45k miles from car max on November 1 2019. I love the car and it was driving great, but a couple of weeks ago i started hearing a strange noise coming from the right side of the car that would only become audible when braking, the closest thing i can compare the noise to is the sound that dolphins make. The steering wheel also began to pull to the right and the steering became very loose. I took the car to BMW and said that they would perform an alignment for the steering issue, but they told me they didn’t find any type of noise or anything that could be causing it. I drove home and the noise was not there anymore, but when i got home the noise came back. Any idea as to what the noise might be or what might be causing it? Thank you.
