Display Groups 005 & 006
DISPLAY OVERVIEWVAG 1551 Display Overview, Display Group 005:
Display group 005, Oxygen sensor learning values bank 1
VAG 1551 Display Overview, Display Group 006:
Display group 006, Oxygen sensor learning values bank 2
NOTES:
These malfunctions are possible with O2S learning value differences (see display group 010, display fields 1 and 2) of more than 8% between display group 005 (bank 7) and display group 006 (bank 2):
^ Spark plug faulty
^ Fuel injector faulty (leaking, plugged)
^ Intake air leak in one bank
^ Heated oxygen sensor faulty or dirty
^ Engine basic setting (control times) NOT OK
If a 9% difference exists between the richest and leanest O2S learning values in one display group, the continued learning of the two affected learning ranges (see display groups 007 and/or 008) are adjusted. The learning requirement display (see display groups 007 and/or 008) of these learning ranges then can not be 1.
If the battery positive voltage (B+) supply to the ECM is disconnected, all values are reset to 0.0%.
