I have a Volvo C30 BJ 2006 with a 2 LITER diesel engine. The car has 180,000 KM on the clock. I can’t say much about workshop visits etc., because the service manual was only run up to 100,000. The car is not in emergency run mode and when reading out in the Volvo contract workshop there were no results. I try to describe the problem as well as possible: the car starts and m As the driving time increases, the output of the tailpipe is increasing. One sees a more or less black cloud when accelerating and taking the gas away. In addition, it is sometimes very much jerking (acceleration and even with the same position of the pedal). On gradients, the car goes into the knees by leaving a huge cloud and the engine gives the noise of the flap (like the lid on the exhaust pipe of an older truck or tractor). You will find pictures of my intake bridge and injection nozzles. I see an increased accumulation of oil there. I suspect that my problem comes through a leak (sucking in or turbo hose). I hope you can help me and tell me what it is. The car has been moved only about 50km since the first symptoms.
