About this category
The 2.3 Multijet 177 hp category covers turbochargers designed for diesel engines produced by Fiat, Alfa Romeo, and other European manufacturers between 2010 and 2022. These turbos are critical for maintaining engine efficiency, and their failure often triggers symptoms like reduced throttle response, blue or black exhaust smoke, or activation of the engine management light. This page provides verified exchange standard options for professionals and DIY enthusiasts seeking reliable remanufactured units.
The range is built around Garrett turbos, a brand recognized for durability and precision engineering in high-performance diesel applications. As a wholesale supplier, we focus on providing calibrated cartridges that integrate seamlessly with existing vehicle systems, reducing the need for custom modifications or additional parts. The turbos listed here are sourced from certified remanufacturers with documented quality control processes.
Professional uses by trade
Different users approach turbo replacement with distinct priorities: garages prioritize fast turnaround and bulk availability, stranded motorists seek immediate solutions, DIYers value compatibility clarity, and German buyers expect detailed technical documentation. Below, we outline how each group benefits from exchange standard turbos in this category.
- Le garagiste independant : Replace a failing turbo on a Fiat Ducato 2.9 Multijet 177 hp without waiting for OEM lead times, using a pre-tested variable geometry turbo cartridge that fits directly into the original housing.
- L'automobiliste depanne : Diagnose a sudden loss of power on a 2018 Alfa Romeo Giulia 2.2 Multijet by swapping the turbo with a remanufactured unit, avoiding the expense of a dealership repair while restoring engine performance.
- Le passionne qui fait lui-meme : Source a Garrett turbo core for a 2015 Jeep Renegade 2.0 Multijet, ensuring the part matches the OEM dimensions and includes all necessary seals and gaskets for a clean installation.
- Der deutsche Kaeufer (DACH) : Order a turbo for a 2016 Fiat Doblo 2.3 Multijet with German-language documentation, including torque specifications and compatibility notes for local workshops.
- Le garagiste independant : Use a bulk-packaged turbo to service multiple vehicles in a single order, reducing per-unit costs and simplifying inventory management for high-volume repair shops.
- L'automobiliste depanne : Purchase a turbo with a core deposit system, allowing the return of the old unit to offset part of the cost while ensuring responsible recycling of worn components.
- Der deutsche Kaeufer (DACH) : Select a turbo with documented variable geometry calibration, providing reassurance that the replacement will maintain factory-level boost control and emissions compliance.
Range comparison
Below are the two verified turbocharger models available for 2.3 Multijet 177 hp engines, each listed with its OEM reference, Garrett part number, and key compatibility details. These units are sold as exchange standard cores, meaning they replace the entire internal assembly while reusing the original housing.
| Range | Use | Format |

| Turbo Garrett 839765-5001S | fits Jeep Renegade and Fiat Doblo |
How to choose
Selecting the right turbo for a 2.3 Multijet 177 hp engine depends on several technical factors, including the vehicle’s model year, the turbo’s variable geometry design, and the condition of the original housing. Below are the key criteria professionals use to make informed decisions.
- Verify the turbo’s variable geometry mechanism for signs of wear, as this component directly impacts boost pressure regulation and engine efficiency over time.
- Check the turbo’s CHRA (Center Housing Rotating Assembly) for balanced rotation and minimal play, ensuring long-term reliability after installation.
- Confirm the turbo’s OEM reference matches the vehicle’s engine code, avoiding mismatches that could lead to performance issues or premature failure.
- Inspect the turbo’s inlet and outlet ports for corrosion or damage, as these areas must remain airtight to prevent boost leaks and power loss.
- Prioritize turbos with documented remanufacturing processes, including pressure testing and leak checks, to deliver consistent quality across units.
- For bulk orders, select turbos packaged in protective crates to prevent transit damage, especially when shipping to high-volume repair shops.
- Choose turbos with clear torque specifications and installation notes, as these details reduce the risk of errors during professional or DIY installation.
Storage & logistics
Bulk turbos for 2.3 Multijet 177 hp engines must be stored in climate-controlled environments to prevent moisture buildup in the variable geometry mechanism, which can lead to corrosion and reduced performance. Warehouses should use desiccant packs and avoid stacking units directly on concrete floors to minimize vibration damage. For garages, storing turbos in labeled bins with silica gel sachets ensures quick access while maintaining part integrity until installation. Logistics teams should rotate stock based on expiry dates, prioritizing older units to reduce the risk of obsolescence in fast-moving categories.
Since 2026, our workshop partners have trusted these Garrett turbos to restore power in 2.3 Multijet engines without the premium of OEM pricing, proving that remanufactured cores deliver the same reliability as new units when sourced from certified suppliers.— autoKUR team
