Just got my 2007 BMW 530XI Wagon back from the dealer, had the PCV valve heater replaced. Overall they did a good job, car is running much better now.
I recently got a code for O2 sensors malfunctioning, dealer told me it would be at least 200 for the sensors plus labour.

So I have a couple questions:
Could the damage caused from the PCV heater malfunction be related to the O2 sensors malfunctioning?
Also I noticed a melted wiring harness that was not replaced (see image).
Also there was a hole in my engine cover from the heat due to the malfunction that was not replaced (see image).

Should I bring it back to them?
