S/V/C70 **Solved** 2010 V70 T6 idle surge
I'm hoping someone can help me figure out a surging idle issue I have with my V70 T6.
Idle surges when warm. You cant hear it when inside the car or really notice it on the tacho, but when your outside the car it's very audible.
When I pull the dipstick, idle clears up and becomes as smooth as silk.
Vacuum in the dipstick tube - relatively high by my standards, but no positive pressure.
PCV box replaced less than 3 months ago.
I do have a leak from the turbo. I know it's a common issue for one of the oil feel line bolts coming loose. Still yet to tighten that up due to the awkward position.
Unrelated to the idle, I've also replaced the Fuel rail pressure sensor, genuine Volvo plugs and cleaned the maf.
Any help would be appreciated.
