I would really like to know how this works out. I have had a similar issue and can't sort it out..
Below is a copy of my issue:
I don’t get any smoke, but I get a smell of oil (maybe diesel) in the cabin, somedays stronger than others.
It is more noticeable when the Aircon is on auto and recirculate, or Aircon off, and just in Fan mode.
There is no smell, if the vents are closed and the fan and aircon off.
I will occasionally notice it when I come back to the car and I've left the vents open and the engine has been off but cooling down.
Someone on the Volvo forum had a similar issue, suggested that
..",vaccum pump seal was leaking and oil was droping on top of the gear box” - not sure if I have the same problem.
I have changed the internal aircon filter recently, but noticed no change in the strength or frequency of the smell.
I have had a look at all the boot/door seals as suggested, but to no avail, and no obvious leaks or “sweats” in the engine compartment, but the important thing is there is no smell if the vents are closed, so it must be coming up from the vents.
The external air intake is from below the wipers and the whole climate system works very efficiently, the recirculate correctly filters out external road/other vehicle smells.
As a test, I placed a strong air freshener in the engine compartment, to see if any smell would leak through from there to the cabin, and am yet to smell it, so importantly, that eliminates fumes from the engine compartment itself.
Update: Took it to my local non-dealer garage today and was told that they suspect that there is oil in the manifold, and that maybe the Turbo is on the way out. -
They were very helpful and gave me the name of another mechanic that knows Volvos very well, so I will be getting hold of them soon as I have time.
However, there is no smoke from the exhaust or engine or anywhere else; the car drives like a dream, and consumption is exactly what it should be.
