Code P1136 Audi Description

The P1136 Audi diagnostic trouble code (DTC) indicates that the Long Term Fuel Trim Additive Fuel Bank 1 system is running too lean. This means that the engine is receiving more air than fuel, leading to a fuel mixture that is too lean for optimal combustion. The Engine Control Module (ECM) monitors the air-fuel ratio to ensure efficient combustion and reduce emissions. When the fuel trim values deviate from the ideal range, the ECM triggers this code. This can result in poor engine performance, reduced fuel efficiency, and increased emissions.
