QuestionHi,
I have gone through a lot with the car and am nearly at my wit's (and checking account's) end. After seeing an independant mechanic who fixed what he could and sent me to the Volvo dealer, I was told at the Volvo dealer that I had to replace the Oil Seperator (PCV BOX) to the tune of $800, of which, $650 was not parts. I asked how they tested for this and if it could be cleaned and was told, "It couldn't be cleaned, and the tech felt the thing blowing rather than sucking." (roughly speaking). After a little research online, I felt that it might be cleaned (or at least the TSB that I looked at suggested cleaning as THE fix, and made no mention of replacement.
I picked up the car and hooked my diagnostic monitor up to it. The original problem that I brought it in for (Check Emissions computer warning, 02 Heat Sensor) now registers as fine (they did upgrade my software with Recall 155). But I am getting a code p0442 (EVAP Emission Control System Leak (small)). The MIL light is on, but it's pretty much always been on, even after multiple thousands spent at my old Volvo dealership in Missouri.
My questions:
#1 - Is this code something that might indicate the PCV replacement? Doesn't seem like it to me, but I'm an economist, not a mechanic.
#2 - Is replacement of the PCV Box really necessary?
#3 - If so, is $800 what I should expect to pay for it?
#4 - Also, can this be done by a regular mechanic, or only at the dealership?
Thanks for your help.
Answerif you have foult code for evap system that you have to find the leak most the time there is hose cracked so you have to find it it goes from fuel tank to intake it recycles the fuel fumes pcv box will not fix that problem for that foult code also it will not fix the o2 sensor problems .cant tell you much like this were and what is broken .
