I recently bought a 00 V70 and have some problems with it. The check engine light is on and a code 1670 is coming up. I have been told it is a common code in Volvo's and is normally an antenna ring. I cannot find an antenna ring anywhere online so can someone direct me to a site were I can purchase one?

Another problem I have with my Volvo is the steering. What happens is the steering feels fine but when you go to turn the wheel either direction it tightens up and loses power steering. I checked the power steering reservoir and it is full so I'm thinking it is the pump and the not the rack. Anyone have any ideas?
