Hi Icelandic, thanks a lot! I went out after dinner this afternoon and found the connection to the exhaust. That did the trick, had to bang it a couple of times with the hammer to break that seal, but it is out now. I also removed the throttle body to clean the EGR passage. No wonder it threw the 2-4-1 code, that port was choked with crud. I think I saw in another posting using a 3/8 drill bit, that worked well to clean the port. IMHO, Volvo should have put that EGR port on one side or on top, that way it would not end up filling with oily stuff that gets carbonized with the exhaust gas. Thank you again.
