Does anyone know where exactly the rear oxygen sensor is located on my '04 807 2.0 gasoline? Somewhere along the exhaust piping I imagine... Would it be a straightforward job to replace myself?

Btw do I read that diagram correctly that the two sensors (front and rear) are identical units? I've been looking at ebay and some list them specifically as "front" or "rear" oxygen sensor..?

I ordered a pair of O2 sensors from China (about 40 pounds) and replaced them. Both sensors were quite easy to find and replace. Biggest issue was the connectors that had me puzzled for a while, until I figured out I had to pull out the red tab to undo the connection.

Btw I did go with the assumption that the two sensors are identical, Bosch part number 0258006028.
