Finally had some time to come back and try and give back to the group.
My 2007 V8 Vantage was throwing a CEL for low or no evap purge control circuit ( dont remember the exact code as I didnt save it ) A common cause of this is to replace the evap pump motor which is located behind the drivers side rear wheel well cover. The part from Aston incudes the entire assembly, pump and a cannister looking thing and is about $300.

For the DIY crowd you can use this Bosch 0261222018, which I believe is a Volvo part., and is an exact replacement, but does not come with the bracket, or the cannister. Now what I discovered in the process is that the canister actually contains an air filter element for the pump. I very carefully popped the top off and mine was actually filled with a bunch of dirt and leaves. I gave it a light brush with soapy water and blew it out. Upon reflection the actual cause of my CEL was very likely restricted flow to the unit because of the dirty filter. Im adding this to a list of once a year or so maintenance items for the car.

Heres a link to the actual pump itself on Amazon should anyone come looking...
Next up, clutch....

Cheers!

 

good to know, thanks.

Interesting. I had the same fault on my 2007 DB9. I replaced the purge valve and the problem went away. After replacing it, it came back on. After clearing the codes, it hasn't shown up again, but because of weather, I havent driven it much. I will check the similar canister (if present on DB9) and see if similar issue.

 

If you can post the actual CEL codes I will try and modify the title of this post to make it easier for others to find. Also if you are friends with a auto parts store guy you can probably just replace the filter. It looks like its a small engine air intake filter, maybe for a generator or lawn mower.
The air filter is in the video at 2:59. The video author identifies it as a charcoal cannister but that is not what it is.
