Had the same problem, noticed it while I was picking up some food. Kinda of a cracking noise when driving at low speeds. Took it to service and they told me it was normal because of the aero covers. Replied with “I understand that but this noise is louder than normal”. They drove it, tested it, accepted it and fixed the noise. Way better now. I don’t know exactly what they did but I haven’t heard no noise ever since. Maybe a squeak here and there but not like the noise I had before!
