FYI,

I called Brentwood Volvo [ where I get my parts ]and
asked how much for EVAP valve 9470775 and they said
only $15. bucks and I said great and they said holllld
your horsees. Why I asked. My man said a download is
needed with the valve install at the dealer. I knew it was
too good to be true. Maybe a service bulliten on this.

Anyone get this done? How much at the dealer to screw
the valve into the charcoal filter and upgrade the software?

I'm checking into this because my idling is hunting a little
and mileage is terrible at 12 [ city ] and my CEL comes On
one week and goes off the next. Will pull codes when I can afford
a reader.

Seems to me that you are assuming that you need that valve when perhaps that's not really necessary? SW is required for some model year applications (not ALL btw) but if all you want is for a dealer to do just what you want, then you need to call their service department for an estimate if out of warranty or you're just willing to pay for it anyway. If it's still under warranty and you have a real "diagnoseable" problem (check engine light, rough running, hard starting, etc), they shouldn't charge you anything but if you're requesting parts that may not be causing a real problem, they won't just do it under warranty just because you want them too. VCNA doesn't allow dealers to do that or everyone would. There is no recall or campaign that requires older parts be automatically replaced even if a newer PN has been made later in production.

If your 'evap purge valve' was bad, you'ld definately get a 'check engine' light before you'ld ever notice a problem with it, actually you'll never see that valve cause a drivibilty or gas mileage problem, just a check engine light.

Thanks Frank,

I'm :

Out of warranty.

Getting good drivability.

Have a CEL that comes and goes when it pleases.

Just wondered if anyone had done this before in case
it turns out to be my problem. Trying to seek a fair price.

I've seen many go bad and the code is stored in memory even if intermitant. I'd have a dealer check the car for fault codes to see if they think your evap valve may be sticking and if SW is required, they'll do it. Short of asking other dealer techs, I'd doubt anyone else here would know any more easy details.
