![]() ![]() labeled Lambda - values are very similar to those in field 2 of this group, usually off by a fraction of a percentage point. So with some puzzling, logging, analyzing and reflection, I have noticed the followuing:Ģ: labeled Load - values range from about 10% at idle to values as high as 100% when driving around.ģ. When I go into OBD2 mode, oxygen sensor data are reported as 0 or 1 rather than a continuous value one would expect from a wideband oxygen sensor.Īfter a lot of Googling, it appeared to me that measuring groups 30-39 would probably relate to oxygen sensors and 40-49 to other aspects of emissions. Unfortunately, I was not able to find documentation for the measuring groups most pertinent to this issue. ![]() Rather than just replace a rear oxygen sensor, I got out my VCDS to figure out what was going on. Those errors, and the excessive soot buildup have apparently been corrected, but I now have recurrent P2271 (rear oxygen sensor rich) errors after driving about 60 miles on the highway. I recently had DPF and EGR cooler replaced because of excessive soot in the tailpipe and insufficient EGR flow rate errors. I have a 2010 Jetta TDI with about 50,000 miles on the clock.
