I began smelling something like fumes and burning in the cabin, and saw smoke from the engine bay. you can imagine my thoughts! I was also hearing an odd abrasive sound like a stone scraping on the brakes and a rattle / loose bolt when driving over an uneven surface. I mentioned this to the dealer (Volvo) and said, they didn't find anything wrong. So I bought an OBD II diagnostic tool that plugs into the car; this ran a test and the result returned an abnormal reading; ECM-P106107 Power pulse system leakage. General fault information. Mechanical fault.

Can anyone help with what this means?
