Turbocharger VOLKSWAGEN Touran 1 (1T1 / 1T2) 1.9 TDI 105 hp

The 1.9 TDI 105 turbo category is dedicated to exchange turbocharger units for the 1.9-litre, 105-horsepower TDI diesel engine found in several European passenger cars from the mid-2000s onward. It gathers remanufactured cartridges and complete turbo assemblies rather than new components, following the exchange-standard principle: the worn unit is returned once the replacement is fitted, under a core deposit arrangement. Garages ordering for a client, drivers facing a stalled vehicle, and owners who prefer sourcing the part themselves before handing it to a professional will find the same reference base here.

The range is built around engine-code compatibility rather than vehicle model alone, since the same 1.9 TDI 105 block was fitted across several marques and body styles. Each reference is cross-checked against known OEM numbers and their remanufactured equivalents, so a BorgWarner-KKK original-design turbo and an SL Turbo exchange unit can both answer the same engine code. This structure lets a buyer move from a vehicle and engine description toward the correct turbocharger reference without needing the original part number in hand.

Professional uses by trade

A 1.9 TDI 105 turbo reference is searched for very differently depending on who is looking. A garage orders against a diagnosis already made; a stranded driver arrives with symptoms and a vehicle description; an enthusiast wants to understand the part before ordering; a German-speaking buyer expects the same rigour in another language. The following points reflect those distinct entry points.

• Independent garage: cross-checks the 1.9 TDI 105 engine code against the customer's diagnosis before ordering the matching turbocharger reference and core deposit terms.
• Stranded driver: arrives with symptoms such as reduced power or dashboard warning lights and needs to match those signs to a specific turbo reference.
• Hands-on enthusiast: wants to understand cartridge geometry and actuator type before choosing between a BorgWarner-KKK original-design turbo and a remanufactured SL Turbo unit.
• German-speaking buyer (DACH): expects the same engine-code precision and reference clarity in German as in French or English before deciding on a part.
• Independent garage: keeps several 1.9 TDI 105 references on hand to cover common failure patterns without waiting on a single supplier for each job.
• Hands-on enthusiast: compares variable-geometry behaviour and CHRA condition across references before deciding whether a full assembly or a cartridge exchange fits the repair.

Range comparison

These four references cover the 1.9 TDI 105 engine code through both an original-design turbocharger and remanufactured exchange alternatives, so the choice can follow engine-code matching first and brand or budget preference second.

How to choose

Choosing between these references starts with confirming the exact engine code, then weighing cartridge and actuator type, and finally the compatibility between a remanufactured exchange unit and an original-design part before finalising an order.

1. Confirm the engine code stamped on the block rather than relying on the vehicle's horsepower figure alone, since several engines share the same power rating.
2. Check whether the turbo uses a variable-geometry mechanism, since actuator type and calibration differ between fixed-geometry and variable-geometry designs on this engine.
3. Decide between a complete turbocharger assembly and a cartridge or CHRA exchange, depending on whether the housing itself needs replacing.
4. Compare an original-design reference such as BorgWarner-KKK against a remanufactured SL Turbo alternative answering the same OEM equivalence.
5. Ask about the core deposit and return process for the worn unit, since exchange-standard turbochargers rely on that returned core.
6. Consider related components such as injectors and the high-pressure pump when recurring symptoms suggest the turbo is not the only part affected.
7. Clarify warranty terms directly with the seller before ordering, since coverage can vary by reference and remanufacturing process.

Storage & logistics

Turbocharger units in the 1.9 TDI 105 category are exchange parts: they arrive as remanufactured or original-design assemblies, and the failed unit is expected back once the replacement is fitted, under the core deposit arrangement. Handling them calls for care around the turbine housing and actuator linkage, which are more fragile than the surrounding engine hardware, and for keeping the returned core protected from further damage until it is sent back. Garages ordering ahead of a repair, and individual buyers ordering before handing the part to a professional for installation, both benefit from confirming the engine code and reference before the unit leaves storage.

Since 2026, we have built this catalogue one engine code at a time. On a reference like the 1.9 TDI 105, matching cartridge, actuator, and flange precisely matters more than the brand printed on the box.— autoKUR team
