When at a standstill, I can feel a slight "thump" coming through the steering wheel at regular intervals of about 1.5-2 seconds. Stereo is off, so its not that. Took it in for service and service advisor felt it too. Head shop tech diagnosed as normal thump coming from ac compressor. I call BS on this as it still does it when AC system is completely off! Just think they were trying to get rid of me. I've searched this forum and other BMW forums, but cannot find anyone with a similar problem. Anyone else here experience this?

BTW, its a 2011 5.0 X5.
