Engine Oil Leaking problems of the 2008 BMW 335

2008 BMW 335i coupe purchased on July 15th, 2013 from carmax. Currently drivable but has major mechanical problems. The extended service contract is still under coverage and is valid at the BMW dealer or any carmax nationwide. When carmax can't fix the car it's hauled over to the BMW dealership to complete the repair and a check would be written by maxcare to the BMW dealer. The only problem is that I've had to take this vehicle in for major repairs several times and I'm not counting maintenance visits. Most of these major repairs were repetitive major jobs such as oil leaks, fuel pressure system, injectors. At one time my car ping ponged between carmax and BMW for close to 2 months. Consider the time I've owned this car for and how long and how many times it's been out of my possession. I was paying a car note for a BMW but driving around in a a base model rental car most of the time. I've got invoices/estimates where the car went in for major repair or diagnosis during these dates: 07/22/2013 05/30/2014 06/13/2014 07/01/2014 11/05/2014 06/25/2015 the repair invoice/estimate on 11/05/2014 was the biggest one. I was very frustrated with the amount of work being done on the vehicle so I got the car appraised to sell back to carmax and they told me $10,000 which I thought was ridiculous. The work done on that car amounted to almost $7,000 or more just on that one invoice which is 70% of the car value. Also, while the car was in the shop I acquired the history of the vehicle directly from BMW. The history stated that the car had oil leak repair at the pan and gasket and the automatic transmission had a leak in 03/06/2013 and the mileage for this record was completely off. As you can see the date of this diagnosis was a few months prior to me purchasing the vehicle.

Took car to dealer to check why I am losing oil. As I suspected, slight oil leak is hitting a hot engine part, evaporating, and not showing on the ground.
