Hello everyone, this is my first post here.

I have a 2006 S40 with 90k miles on it.

The check engine light came on right after i got home from a long road trip.

I had it scanned and and was told that it was: "bank 1 system 3 lean"

it is also making an audible clicking/sucking sound that appears to be coming from mid motor area, right under the black plastic engine cover. BUT ONLY after it has been running for a little while.

Thanks in advance for your help.

Chad
