Repaired Turbo Fiat Alfa Lancia Opel 1.3

The turbocharger with OE code 55212341 è is a supercharging component used on numerous vehicles of the FCA group (Fiat, Lancia, Alfa Romeo) and Opel with diesel engine 1.3 Multijet / CDTi. This turbocharger belongs to the BorgWarner BV35 family, designed to ensure good performance in terms of torque at low revs and low consumption, while maintaining compactness and reliability.à.

Technical characteristics

• Geometry: fixed, with wastegate valve
• Cooling: oil only
• Actuator: pneumatic
• Maximum boost pressure: up to 1.3–1.4 bar

The central body è made of high-strength steel with an Inconel turbine housing and lightweight alloy compressor wheel to reduce inertia.

DIPA può intervene to review this component as wellì which is important for the proper functioning of the engine.

Functionalityà

The function of the OE turbocharger 55212341 è is to increase the pressure of the’air intake in the cylinders, improving the’volumetric efficiency of the engine and increasing power and torque. The wastegate system allows limiting the maximum pressure, preventing overboost phenomena and protecting the internal mechanics of the engine.

Being devoid of variable geometry, this turbo è is less complex from a maintenance perspective but requires that the wastegate and the’actuator are perfectly efficient to ensure a correct response.

Brand and model on which the part è is mounted

The OE turbocharger 55212341 è has been mounted on a wide range of FCA, Opel, and Chevrolet vehicles equipped with the 1.3 diesel engine, including:

Fiat

• Doblò (Bus, Cargo, Flatbed)
• Fiorino (Chassis/Limousine)
• Idea
• Punto
• Punto Evo
• Qubo
• Strada

Opel

DIPA recommends to always check the compatibilityà of the spare part before the’purchase.

Defects and causes

The main defects found in the OE turbocharger 55212341 are generally related to:

• Pressure drop: due to wear of the impeller or axial play of the’shaft.
• Faulty wastegate actuator: pressure loss or broken diaphragm, preventing the valve from opening correctly.
• Oil leaks: caused by clogging of the lubrication duct or obstructed oil return.
• Abnormalà noise: a signal of contact between the impeller and the housing due to bearing wear.
• Stuck turbocharger: in case of insufficient lubrication or delayed oil change.
• Stuck wastegate: canò cause overboost or total pressure loss.

The’use of non-compliant oil or clogged filters significantly contributes to the reduction of the turbocharger's lifespan. Additionally, failure to replace the exhaust gasket or damaged manifolds canò generate black smoke and loss of efficiency.

Final conclusions

The OE turbocharger 55212341 is a critical component for the performance of the diesel engines 1.3 Multijet and CDTi used by Fiat, Opel, Alfa Romeo, Lancia, and Chevrolet. Its operation is based on a simple yet effective geometry, with a pneumatic actuator and integrated wastegate.
