Well finally go my car back from the dealer today. They diagnosed the issue to faulty wiring on the direct injection sensor to the harness. So the harness has been replaced and the car is fine now. Basically as the voltage changes due to the loose wire, the direct injection was told to dump fuel immediately followed by a lean code etc read the above for better description. I'm really happy with the service tech and the local dealer how they handled this now and happy to finally have the car.
