This hybrid turbo for engine options 2.0 TDI 120, 136 and 143 hp is fitted with an internal mechanism designed to adjust the compression capacity and flow rate dair. The three available models feature a high-flow MFS compressor wheel, a 360° bearing stop and high-speed balancing on a Cimat VSR bench..
The documented assignments relate to various Audi A4, A5, A6 and Q5, as well as the SEAT Exeo and Exeo ST. Compatibility must be confirmed using the turbo’s part number dthe vehicle’s origin, engine code and precise specifications.
This unit uses a high-flow MFS impeller with a specific geometry. It aims to alter the compressor’s behaviour without it being possible to determine any gain in power independently of the engine configuration.
The wheel oversized and the re-profiling of the casing d’The intake valves adjust the flow’ d’air in this configuration. The result also depends on the boost setting and the overall engine tuning.
This version features the largest documented compressor wheel for this product. Its sizing can affect the available flow rate, response time and optimal operating range; it is still essential to ensure the motor is configured correctly.
A hybrid turbo retains a turbocharger design suited to modified internal components. Depending on the stage of preparation, the changes may relate to the compressor wheel, its dimensions, the geometry of the blades, the casings, the thrust bearing system or the balancing.
The aim is d’adjust the compression capacity and flow rate’ dair. However, a hybrid turbo is not defined solely by the appearance of its impeller: its dimensions, geometry, the machining of the housings and the overall consistency of the assembly determine its performance.
MFS stands for ‘Milled From Solid’, meaning a wheel machined from a solid block. This manufacturing process does not, on its own, guarantee an increase in throughput dair. A standard MFS wheel can retain a geometry equivalent to the original.
An MFS wheel Performance may have a diameter, profile or blade configuration suited to the intended purpose. For this product, the dimensions and configurations vary depending on the course selected.
A standard MFS wheel can be just as shiny as an MFS wheel Performance. It is not its appearance that determines its performance, but its geometry and its ability to move more dair. A higher flow rate can help to increase power output when the engine and its control system are set up accordingly.
The compressor wheel draws in and then compresses the air fed to the engine. Its diameter, profile, height, width and the arrangement of its blades all influence its aerodynamic behaviour. The right geometry can move more dair under certain operating conditions.
The result also depends on the compressor housing, the turbine section, the boost pressure and the mapping. A larger wheel therefore does not automatically guarantee better performance and may affect response time.
The 360° bearing stop – as documented for Each bearing helps to distribute the axial forces acting on the rotating assembly. It does not exempt d’proper lubrication nor d’a compliant installation’.
Each preparation is balanced at high speed, up to 150,000 rpm, on a Cimat VSR test bench. The purpose of this balancing is to minimise vibrations and mechanical stresses on the rotor, although it cannot compensate for a fault d’oil supply or incorrect installation.
The engine management system needs to be adjusted for make the most of the hybrid turbo’s features. The boost actuator must be adjusted during installation and when reprogramming the control unit.
Depending on the level of preparation, the mapping, the fuel injection, the exhaust system and the air cooling d’The intake, clutch or gearbox may need to be checked or adjusted’. The hybrid turbo alone does not guarantee a power boost.
⚠️ WARNING — IMPORTANT BEFORE ASSEMBLY
Identify and rectify the cause of the previous fault. Carefully check the lubrication circuit, the supply and the return doil, as well as ensuring that all ducts are clean.
Check the intake, ensure there are no foreign objects and check the condition of the associated components. Carry out the priming in accordance with the relevant guidelines and follow the manufacturer’s instructions.
If a lubrication fault is not rectified, it may lead to the turbocharger failing again.
Check the part number marked on the turbocharger d…the original and compare it with the OEM and manufacturer’s specifications in this data sheet. Also check the make, model, generation, body style, engine type, power output, production period and engine code.
The same engine can be fitted with several different turbo set-ups. The exact reference therefore remains the key element for confirm compatibility.
⚠️ Check your turbo’s part numbers
Before placing your order, Compare the part number on your turbocharger d’origin’ using the references given in this fact sheet. Having the same motor does not always guarantee compatibility.
If you are in any doubt, please contact us, providing the legible reference number of your turbocharger and your vehicle details.

A single engine type may have been fitted with several different turbochargers depending on theYear, power output, engine version or technical evolution.. The application alone is therefore not always sufficient for to accurately identify the correct turbo.
Before ordering, note down the part numbers shown on the identification plate d of your old turbocharger. This may be d an OEM part number or d a part number from the turbo manufacturer.
Compare these part numbers with those listed on our product pages.. If in doubt, our team can help you verify the part number you are looking for before you place your order.
A loss of power, an unusual whistling noise, oil consumption d, abnormal smoke or poor engine performance may be linked to a turbocharger fault.
However, a fault that appears to be turbo-related may also stem d from a lubrication issue, d from contaminated oil, d from a foreign object, from the intake or exhaust systems, or d from another engine peripheral component.
It is therefore important to investigate the cause of the fault before fitting a new turbo or a new Cartridge.
Since 2012, ALFI TURBO has been assisting private individuals and professionals in identifying and replacing turbochargers.
A turbocharger failure may be the result d of another engine problem. Before fitting d a new turbo or Cartridge, identify and rectify the cause of the original fault to d avoid d damaging the new part.
