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: Address 01: Engine Labels: 04L-907-309-V1.clb Control Module Part Number: 04L 906 021 EM HW: 04L 907 309 D Component and/or Version: R4 2,0L EDC H22 8151 Software Coding: 111D001A047401081000 Work Shop Code: WSC 47914 001 1048576 ASAM Dataset: EV_ECM20TDI01104L906021EM 002009 (SK37) ROD: EV_ECM20TDI01104L906021EM.rod VCID: 74E769D7DFBB262616-8020 1 Fault Found: 19249 - Oxygen (Lambda) Sensor B1 S1 P2195 00 [237] - Signal too Low (Lean) MIL ON - Confirmed - Tested Since Memory Clear Freeze Frame: Fault Status: 00000001 Fault Priority: 2 Fault Frequency: 2 Mileage: 191240 km Date: 2020.12.17 Time: 13:57:01 Engine speed: 2047.50 /min Normed load value: 0.0 % Vehicle speed: 73 km/h Coolant temperature: 90 °C Intake air temperature: 78 °C Ambient air pressure: 1010 mbar Voltage terminal 30: 14.680 V Unlearning counter according OBD: 40 Mass airflow sensor 1 bank 1 airflow: raw value: 604.0 mg/stroke Mean injection quantity: 0.00 mg/stroke Particl.filt.: different.press.sensor 1 bank 1: adaptat. value: 54 hPa O2 sen. bank 1 upstrm oxi cat: elec. correct. pump current: 0.0032227 A Oxygen sensor bank 1 before oxi cat: heater activation: 47.949 % O2 sensor bank 1 upstrm oxi cat: status of signal quality: 1 Oxyg.sensor bank 1 before oxi cat: curr.pump curr.adaptation: 0.8875 Readiness: 1 1 0 0 0 After I erase this one, after approximately 3 weeks MIL ON comes again with no simptoms at all.
