P0455 and P0410 codes on a '98 V70

i had a recurring P0455 code which ended up being a cracked hose at the charcoal canister and a cracked vent hose on top of the gas tank (make sure you replace this with the volvo hose, not hose from autozone).

I did the replacement with the VW pump and it worked great. Did not replace the valve and it let water in the pump and again failure. I drilled holes in the pump bottom, but not in the right place. If you do the VW pump fix, replace the valve and drill holes. The set up for these pumps is bad, being located under the battery. The bypass was easy and so far works.

The first one (which has come up since I got the car in 07) is P0455 EVAP Evaporation control system leak (Large), in the last 3 years, I've had all the O2 sensors replaced (that's what the mechanic said it was.) What else can I do for the EVAP code?

I've had the P0455 code for 6 months. Mechanics have replaced purge valve, vapor canister filter, roll-over valve, shut-off/change-over valve, fuel filter, and I've replaced gas filler cap. Still can't find problem. I can't personally find the charcoal canister -- I think it is underneath behind the front bumper by the left front wheel, but not sure.
Can I get access to and/or see it if I remove the battery and battery tray or does that just reveal the air pump (replaced that, too about 5 yrs ago)? At this point, it's trial and error with mechanic but I'm thinking it will take a smoke test. First, would prefer to get view of charcoal canister and see if the J-hoses on top are the culprit(s). Not sure how to narrow in on where the canister is and how to get access to it. Unfortunately, I live in a condo complex with no garage and working on your car outside or in the open carport is "frowned upon". Any insight on how to narrow in on the charcoal canister and how to get to it without removing would be appreciated.

Crawled under my car this weekend and found the canister close to the gas filter. Mine is a 98 V70 but not an AWD, so it might be different on yours. My "J" hose was in great shape, but the "L" hose was shot at both ends. and I was showing the code again. Went with some gas line and clamps and we'll see what happens. I have heard of the canister being at the front fender. Knowing something has to be there, should make it easier to find.
Good luck
Shane

Shane,
Can't find picture of what it looks like -- is it rectangular, round/cylindrical, other?

Thanks, at least that's more than I had found before. Mine is AWD model V70XC, so don't know for sure if it is located by the left front tire or right rear. The vacuum diagram pasted under the hood leads me to believe it is by left front tire but it is only a schematic and can't say for sure.
If I did ever get it loose and out, I'd be concerned (for me) to be able to disconnect the J-hose and L-hose at both ends and either reconnect or replace without tearing half the engine compartment apart (battery, tray, air cleaner housing, maybe left wheel well trim, etc.). Meanwhile, next step is to try to i.d. the canister based on the website info you supplied. Again, thanks.

The other Q I wonder about is, if I find that there is a leak in the line running from engine compartment clear back to the fuel tank, how in the world does someone replace that line -- it is hidden in numerous places and goes who knows where -- would it be like electricians "fish" a new wire thru a wall, tieing the wiring on to a "fish" line and pulling it thru, hoping it doesn't get disconnected somewhere in between?

That long line is visible, and you will track it easily, but it rarely fails - extremely hard material.

Good to know. Thanks for the information.
