O2 Sensor

I took possession of my new Golf TDI about a week ago. This morning, with about 150 miles on it, the check engine light came on.
In the time waiting for the car to arrive, I've been reading pretty much all the of the website and forums (Thanks Chitty for such a great work). I knew it was probably a problem with the O2 sensor, so I brought it immediately to the dealer without turning the engine off.
They read the code and told me there was a Bulletin advising to change the O2 sensor when that problem happens, so it seems it's a known issue. I'm now waiting for the parts to arrive. FYI, my car was built February 24 (yup it took forever to leave Germany, nobody knows why, but that's another story)

I'll try to get as much documentation as I can from the repair and post it here.

So I just got my car back after they changed the O2 Sensor and updated the software per technical bulletin.

Here is the info I got from my repair:

Cause: Diagnosed to Bank1 Sensor 2 Oxygen sensor, electrical malfunction
Technical Bulletin 2022741
Replaced Post catalytic converter oxygen sensor
Performed software update

I also asked for the diagnostic log, but looks like I just got the 1st page containing the 1st event of the 2 recorded:
Code: 05081 P13D9 000
Cylinder 4 internal pressure sensor
implausible signal
sporadic

I suppose the second one is the 02 sensor code. I'm wondering what that 1st one is. Maybe it's just noise due to the o2 sensor?

Here are the scan (anonymized) of the "invoice" and diagnostic log:
