2000 V70xcse Overboosting

Post by **shiloh51933** » 30 Sep 2016, 05:44

A pending code for overboosting after I was opening her up on hwy. She runs he but she's off, she feels like there's an open somewhere in the aircharge tubing.
This happened after letting a shop touch her, I didn't have time for the heater core hoses but it needed to get done. Funny thing is that my wife's 2004 xc70 has an underboosting problem after letting same shop replace her steering coupler, same thing I had no time to do it myself. Any opinions?

Sounds like they knocked off the vacuum lines going from the TCV. In both cases.

Do you mean boost control valve on air box? That's one of first places I looked.
