P1141

Fuel Trim Load Group Above Limit Bank 1

2014-2014 Audi A6 3.0L Supercharged V6

High SeverityPowertrain

The 2014 Audi A6 is equipped with a 3.0L V6 engine. Below you'll find detailed p1141 diagnostic code information including labor time estimates, cost ranges, and technician notes specific to this engine configuration.

Description

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.
