ŚredniCode P3275 is a manufacturer-specific error, most often indicating too low air flow rate (MAF) in bank 2 (BMW) or an open circuit in the ground wire of the lambda sensor bank 2 (Audi/VW).
OBD-II (EN): Manufacturer Specific P3275 Low Air Flow Bank 2 or Lambda Sensor Ground Circuit Open Bank 2
Code P3275 is a manufacturer-specific error that most often concerns the air flow measurement system (MAF) or lambda sensor bank 2 – the specific cause depends on the vehicle make (BMW, Audi/VW). It can cause increased fuel consumption, power loss, and incorrect engine operation. Diagnosis with an OBD-II scanner and verification by a qualified mechanic is recommended.
Symptoms
- Check Engine light (MIL) on the dashboard - Increased fuel consumption or rich/lean air-fuel mixture - Irregular engine operation, possible vibrations or jerking during acceleration - Deteriorated dynamics and noticeable power loss - Possible incorrect lambda values displayed by the diagnostic scanner - For EGR: black smoke from the exhaust pipe and increased emissions
Possible causes
- BMW: too low signal frequency from the mass air flow sensor (MAF) on bank 2 – contaminated or damaged MAF sensor - Audi/VW: open or short circuit in the ground wire of the lambda sensor (wideband) bank 2 - Leak in the intake air system or vacuum line (false air) - Worn or damaged electrical connector of the MAF sensor / lambda probe - Faulty EGR valve or blocked EGR passages (generic version of the code) - Damaged wiring harness or connector corrosion due to moisture
