P0130 O2 Sensor Circuit Malfunction (Bank 1 Sensor 1)
P0135 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
I would imagine if your replaced the O2 sensor that it would take care of the PO135 as well. Just a guess however. I would think that it would be located on the exhaust manifold.

MBWorld Fanatic!
This may help. I replaced mine last year.
I did the drivers side primary from underneath on the drivers side. Someone once explained that they did the drivers from the top, but from the bottom wasn't bad. The drivers side is the most difficult. The others are simple. The passenger side primary was done from the engine compartment on the passenger side. Both secondaries were done from underneath on the passenger side. All O2 sensor wires from plug into a junction box on the passenger side. Each of the factory O2 sensor electrical plugs is unique and cannot be incorrectly plugged in. If you've never done O2 sensors before - I did mine when the exhaust was cool, and I use antiseize. Some people don't.
