I just had a chat with my audi; it says
17559/P1151/004433 - Long Term Fuel Trim Additive Air; Bank 1; Range 1: System too Lean
From Ross-tech:
Possible Symptoms
Malfunction Indicator Lamp (MIL) active
Possible Causes
Intake System faulty/leaking
Fuel Pressure, Fuel Pressure Regulator and Fuel Pump faulty
Fuel Injectors faulty/leaking
Exhaust System faulty/leaking
Activated-Charcoal Filter/System faulty/leaking
Secondary Air Injection System faulty/leaking
Lambda/Oxygen Sensor(s) before Catalytic Converter faulty
Lambda/Oxygen Sensor(s) after Catalytic Converter faulty
Possible Solutions
Check Intake System for Leaks
Check Fuel Pressure, Fuel Pressure Regulator and Fuel Pump
Check Fuel Injectors
Check Exhaust System for Leaks
Check Activated-Charcoal Filter/System
Check Secondary Air Injection System
Check Lambda/Oxygen Sensor(s) before Catalytic Converter
Check Lambda/Oxygen Sensor(s) after Catalytic Converter
Any ideas? considering I have starting problems only when the engine is "medium warm"
