Hi all
2014 Audi allroad 2.0 60K miles. Borrowed my friends VCDS
Been getting this every so often. used to self clear but now returning.
Trips usually after a mile or so after restart when engine is hot.
2821 - Bank 1; System Too Lean off Idle
P2177 00 [101] - -
Not Confirmed - Tested Since Memory Clear
Freeze Frame:
Fault Status: 00000001
Fault Priority: 2
Fault Frequency: 1
Mileage: 97738 km
Date: 2019.11.29
Time: 13:38:25
Engine speed: 1694.00 /min
Normed load value: 17.3 %
Vehicle speed: 68 km/h
Coolant temperature: 96 °C
Intake air temperature: 33 °C
Ambient air pressure: 1010 mbar
Voltage terminal 30: 14.771 V
Unlearning counter according OBD: 80
Engine status: COENG_RUNNING
Engine status-Test_Program_Co Eng st COMPU VERB UBYTE: 3
Back story abut 9 months ago had this same code and replaced the oil breather assembly which fixed it (along w/ an erratic idle)
Idle is ok now.
Data logged (3 mile drive) Long term adaptation of mixture formation bank 1. Running between 3 and 7% typically 5% Is this bad?
Short term bounces +/- . Air leak somewhere? Smoke test next?
Also seeing cylinder 1 and 3 misfires during warmup / first mile driving (not at start or hot) Replaced coil packs and plugs not change Clys 2 and 4 are quiet.
Thanks
