Condition
The customer complains that the engine runs rough or the vehicle shakes for a short time after refueling.
The condition may occur even if the fuel tank is not filled completely.
Technical Background
There is a possibility that, on 4-cylinder Macan vehicles produced between September and November 2022, debris
from the production line became stuck in the tank vent valve. This may cause intermittent sticking of the tank vent
valve, causing a rough running of the engine shortly after refueling.

Create a PIWIS Tester logging file of the following actual values while the vehicle is exhibiting the complaint 		
		condition.
		
Engine electronics (DME) → Actual values / input signals:
		- Intake manifold pressure sensor, actual value
		
- L010_Fuel trim mean value, bank 1
		
- L050_Actual lambda value ah. of cat. con. bank 1
		
- L130_Lambda controller correction downstream of cat. conv. bank 1
		
- L150_Activated charcoal filter load
		
- L170_Tank vent. valve pulse/duty factor
		
- Long-term lambda mixture adaption, bank 1
		
- M120_Misfire counter for all ignitions
		
- Oxygen sensor downstream of catalytic converter, bank 1: Short term adaption of mixture formation
		
		
Please ensure that the PIWIS Tester logging file is attached to the PCSS job. Please also note the time 		
stamp(s) in the video where the condition is present (e.g., 0:30 - 1:20).
