I have a manual 2006 Volvo XC90 D5 185HP (Odometer 220192km). The engine is vibrating, causing the cabin to move and vibrate as well. When fuel is less than half a tank the car goes into limp mode. And now the car is very laggy and jerky in the movements. It has difficulties starting when the temperature is around 32F. And the motor is very noisy. Is the motor near its life-cycle? Oil-level seems to be OK, refueled two months ago. Attached a video of the engine. Any suggestions on what could be wrong? Thanks!
