Hi I don't know much, but this morning my v70 2.5t 2006 gave me the messege reduced engine power or something alog those lines and the dtc code 640c. It had a lack of power.
When I look under the Hood I found that a pcv pipe had a crack in it and when I touched it ,it broke of. So I wonder if these two things are connected.

Vacuum or boost leak. If you have a leak like you have, it is likely the issue. It throws a code for anything that is in the intake air system when you get a leak.
