Hello to the forum!
I'm a newbie and definitely not a mechanic but I'm trying to learn things day by day! I will try to describe the issue I'm facing as detailed as possible.
So I own a 2010 VW Polo 1.6 TDI CAYB for the last 5 months. It is low mileage (~75K miles) and in good shape overall (it only had an exhaust blown near the DPF which is well welded). I am the second owner since new and based on the paperwork the car had the emissions fix applied in 2017.
Accidently I noticed an idle hunting ONLY when car was hot (normal temperature), idle and stationary and with AC or rear window heater OFF. When I was giving load to the engine (e.g. turn AC ON) the hunting was disappearing. I had no warning lights, no power loss, nothing strange at all.
I visited my local VW main dealer for a full health check regarding the issue. Their diagnosis didn't come with any faults, no deviations, nothing at all.
I then consulted a reputable TDI specialist firm in UK and they told me that I should have an auto electrician look at this issue as first port of call. Indeed I visited an auto electrician in my region but the result was the same as VW main dealer: they couldn't find any issue even when they plugged the car and monitor it while the hunting was happening.
After that I had a talk with a friend of mine who is a tuner abroad and told me that in any case it should be could to reverse the emissions fix. Thus I was referred to a tuner in my region who did the rollback in the ECU software (from 9979 to 9970) and remove the flow transformer installed in front of the air mass sensor).
Miraculously the idle hunting disappeared! But after some days I noticed that it didn't; it was just happening in other timing:
When car is hot, on idle, stationary with engine on and without any load there is NO idle hunting. But when I turn off the engine and turn it on back again then after 10 seconds the idle hunting begins!
After that I asked a good friend who is mechanic (but not vag specialist!) for his opinion. So he plugged his ODB reader and we noticed that when the idle hunting was happening the O2 sensor was not working (reading was 0v). We monitored this and we saw that either when the car is cold or hot it takes a lot of time in order the O2 sensor starts working (giving readings >0v). For example I measured it from cold start and car moving and it takes almost 8-10 minutes in order the O2 to start working. It drops to 3-5 minutes from hot start and car moving. Also noticed that when engine is cold and car stationary it takes over 20 mins, and when engine is hot and car stationary over 10-12 mins.
I confirmed this with my VCDS as well as I run an auto scan which came with no fault codes at all. So I decided to check the O2 sensor. This specific car has only one pre cat O2 sensor (bank1). I checked the fuses, nothing wrong. I check the voltage in the O2 connector and I also check the voltage in the wiring which connects the O2 sensor with the ECU (in this case I only checked the connector which plugs into the O2 sensor. I found that all measurements were right according to specifications.
Then I replaced the O2 with a NGK/NTK one but the problem is still here.
I tried to unplug the O2 (and a couple of other sensors) while they were working to see if there is any difference but I came with nothing. I only noticed that when I disconnected O2 while it was working and connecting it back again it continued working. Only if I turn off the engine and turn it on back again then it needs a lot of time to start giving reading >0v
Here is a log of the VCDS auto-scan after I unplugged the sensors while working:
and this is the log when I cleared the faults:
I noticed that fault 01314 - Engine Control Module 013 - Check DTC Memory - Intermittent was still there and I managed to clear it manually (through VCDS)
This is my most recent VCDS auto scan:
I also took some measurements of the injectors while idle hunting is happening
Here are two logs for your review:

and
https://www.mediafire.com/file/rjprscpcxz2dr9h/LOG-01-IDE00365ENG99400__2.pdf/file
What is your thoughts and advise on these? Is it normal for the O2 to show 0v readings? And to take so much time to start "working"?
Please accept my apologies for the long post and for any mistake in the above. Any advise/guidance for what to do next will be much appreciated.
Regards
Zach

Here are two logs for your review:
https://www.mediafire.com/file/hjk9031htsajxnb/LOG-01-IDE00365ENG99400__1.pdf/file
and
https://www.mediafire.com/file/rjprscpcxz2dr9h/LOG-01-IDE00365ENG99400__2.pdf/file
What is your thoughts and advise on these? Is it normal for the O2 to show 0v readings? And to take so much time to start "working"?
Please accept my apologies for the long post and for any mistake in the above. Any advise/guidance for what to do next will be much appreciated.
Regards
Zach
