I'm unable to open these linked pictures, not sure why but it might have been better if you'd used the tool to embedded them in your post in the usual way.

Regarding the oxygen sensor problem, I did suffer a repetitive warning light on this issue for several months (I deleted the stored P014c diagnostic trouble code each time) but the problem cured itself before the dealer service. I discussed this with the technician who suggested that an active DPF regeneration probably burnt off the soot build-up. In any case, he informed me that the batch software updates, installed during the service, would cause the ECU to become more tolerant of a slow response from this sensor in the future.
