2004 C230 Kompressor P0170 Code
2004 C230 Kompressor with 160000km on it.
Fuel trim is rich.
LTFT 7.81%
O2 sensor around 0.45V at idle, fluctuates between 0.6V and 0.8V when driving
MAF around 2.5g/s idle in neutral, 3g/s idle in gear.
rpm 760s in neutral, 670s in gear.
Ignition TA 31%.
No appreciable power loss or rough running.
New fuel pump, fuel filter, but problem exists before those.
Any idea how to locate the problem?

Pull the harness off of the O2 sensor and check for oil in the wire harness. I had to have my whole harness replaced due to the leaking cam magnets/sensors.
