Code P1141 Audi Description

The P1141 diagnostic trouble code (DTC) in Audi vehicles refers to a Load Calculation Cross Check Range/Performance issue. This code indicates that there is a discrepancy between the expected load calculation and the actual load calculation in the engine control module (ECM). The load calculation is a crucial parameter used by the ECM to determine the amount of fuel injection required for optimal engine performance. When the ECM detects that the load calculation is outside the expected range or not performing as it should, it triggers the P1141 code.
