Greetings to everybody,
 
	I really hope that someone can provide me with guidance, since I find myself in a challenging situation. I just acquired a 2007 BMW 320i, and everything seemed OK upon collection - no engine management light illuminated, and it seemed to operate well. I spent almost all my resources on this vehicle, leaving me with little funds for maintenance, and I was thrilled to finally own my own BMW.
 
	Shortly after initially driving it on the freeway, the engine management light illuminated in yellow (or orange), and I began to see more smoke from the exhaust. I am providing a Google Drive link to the video to illustrate the situation, since I am really worried.
 
	I attempted to return to the dealer; however, they are refusing to accept the return, asserting that the item was in satisfactory condition at the time of sale. I am apprehensive about a substantial repair price since my financial resources are currently limited. I am uncertain whether others have had a similar situation or can identify the potential cause.
 
	Here is a concise summary:
 
	BMW 320i, 2007
 
	No complications prior to entering the freeway
 
	The engine management light illuminated (yellow/orange).
 
	Prominent smoke emanating from the exhaust
 
	18.5 miles per gallon shown on the dashboard
 
	 
	I would really appreciate any assistance or guidance you can provide. I much appreciate it!
