Hello guys,

 

Can someone help me to read this parameters from the two scans, it all comes out without any reason (MIL ON), all works like normal after that only the check engine remains on, I scan with VCDS and on engine module appears the P2195 (I will attach the 2 freeze frames), I would like that someone with more knowledge then me to read this 2 errors and tell me if it's the O2 sensor faulty or someting else is causing this error to appear.

 

Car is a Octavia RS TDI with DSG from 2015 with MTM M-Catronic fitted since the first kilometers of the car (now has 191xxx km)

 

Bellow is the scan from 22.12.2020:

After I erase this one, after approximately 3 weeks MIL ON comes again with no simptoms at all.
