P1141high severityPowertrain
Fuel Trim Load Group Above Limit Bank 1
on 2017 Audi A6 3.0L Supercharged V6 · FWD
What this code means
The ECU detected that the fuel trim adaptation value for a specific load group on Bank 1 has exceeded its allowable range. This is a more granular fuel trim fault than general lean/rich codes.
Symptoms
- Check Engine Light
- Poor driveability at specific load points
- Rough running under load
- Possible misfire at certain RPM ranges
Common causes
- Vacuum leak that worsens under load
- Fuel injector performance degradation
- MAF sensor drift at specific airflow ranges
- Intake manifold flap issue
- Fuel pump losing pressure under load
Diagnostic steps
- Monitor fuel trims across RPM and load ranges
- Perform boost leak test on turbocharged models
- Test fuel pressure under load
- Check MAF sensor readings vs specifications
- Inspect intake manifold flaps
Repair notes
Address the load-specific fuel trim issue by repairing vacuum leaks or replacing degraded components.
