Weird driving feeling + oil consumption - MY2018 Volvo V90 D

[kristian568]

Hi, I think I have some problems with my Volvo V90 D3 with 200.000km on it. A few days ago my mechanic performed a regular service and as he popped off bottom engine protection I saw some oil residue right between the engine and transmission. Before and after the service the car is feeling strange it sometimes hesitate to drive off from 0 as well speeding up while driving and struggles to keep higher speed. When accelerating there is a slight hiss heard from outside or a hum as heard from the inside.There is no warning lights or codes throwing out and the car has higher oil consumption and a higher fuel consumption. Sometimes, not always when I turn off the engine and come back after an hour, hour and a half the car has that weird rough idle feeling (revs don’t change or jump up and down) for 15-20 seconds after turned on and then back to normal. Did anyone had the same/similar problem cause I searched in different forums and didn’t really find anything similar? Are those different problems or one problem that’s causing these I don’t even know if errors or am I just imagining it haha 😁 Anyways thanks for your replies ☺️
