P2279 on Opel
Intake Air System Leak
P2279 on Opel vehicles indicates intake air system leak. Au7o has documented this code across 1 Opel model — most commonly on Zafira. This code means the engine computer detected an air leak in the intake system downstream of the mass airflow sensor (unmetered air entering the engine). Because this air is not measured, the engine may run lean, idle roughly, or behave inconsistently. The computer flags it when fuel trims or airflow readings indicate more air is reaching the cylinders than the sensor accounts for. It is usually not an immediate safety issue but can cause drivability problems, poor fuel economy, and other related lean codes. Typical repair costs on Opel range from $50 to $350, depending on the specific model and root cause.
Common Causes of P2279
- •Cracked or loose intake hose / air duct after the MAF
- •Vacuum leak (hoses, gaskets, PCV)
- •Loose or damaged intake manifold gasket
- •Faulty or dirty mass airflow sensor
- •Leaking throttle body gasket
- •Unseated or cracked intake boot clamp
- •Failed PCV valve or hose
P2279 on Opel by Model
Opel Zafira(1 issue)
- 1.9 CDTi Swirl Flap (Drallklappen) Linkage Failure (Z19DTH/Z19DT)2005-2014
The 1.9 CDTi engines in the Zafira B use intake-manifold swirl flaps controlled by a plastic actuator linkage. The linkage rod and bushings wear or break, so the flaps no longer move correctly, triggering limp mode and stored fault codes P2279 (intake air system leak) and/or P2075 (intake manifold runner position sensor/switch). German owners (motor-talk.de, zafira-forum.de) report this commonly around 90,000-150,000 km, often alongside EGR and DPF clogging on the same engine. Left unrepaired, a flap can break off and be ingested by the engine.

What does P2279 mean on Opel?▼
P2279 stands for "Intake Air System Leak." This code means the engine computer detected an air leak in the intake system downstream of the mass airflow sensor (unmetered air entering the engine). Because this air is not measured, the engine may run lean, idle roughly, or behave inconsistently. The computer flags it when fuel trims or airflow readings indicate more air is reaching the cylinders than the sensor accounts for. It is usually not an immediate safety issue but can cause drivability problems, poor fuel economy, and other related lean codes. On Opel specifically, this code is documented across 1 model.
What causes P2279 on Opel vehicles?▼
