mk4 1.8T AUM
Have a little problem with my file
this error comes randomly and sometimes with CEL

Code:
16514 - Oxygen (Lambda) Sensor B1 S1: Malfunction in Circuit
P0130 - 35-10 - - - Intermittent
16514/P0130/000304 - Oxygen (Lambda) Sensor B1 S1: Malfunction in Circuit

o2 sensor are new Bosch unit
harness - ok
maf - ok
logs - ok (actual lambda = specified and everytime i logging it - sensor works)
no other DTCs
LTFT -7 .. -15% (working on it)
STFT 0.5%

searched it on web - one guy has the same problem with his mapped passat. solution is fixing file by the tuner. so i dont know what is he fixing Sad
any ideas?
thanks

IIRC, this is covered in the "Emissions delete and setting actual readiness" thread.

Is it logical to let adaption happen, then read adaption values off with Lemmiwinks and change maps according to the percentages? Why or why not?

im looked to the sensor during cold start and warmup and it is very rich (and exhaust smell too), adaptation channel in default value
just have no time to experiments with it
but i think lowering the KFFWL maps is a way to solve this problem

Warmup is open loop.

Hello ! after turning off the second oxygen sensor, an error 16514 appears, you have found a solution on the KFFWL map?
