Turbocharger BMW 320d (E46) 320d 150 hp

The 320d 150 hp category brings together turbocharger references built for this specific engine and power output, presented as standard-exchange units rather than new parts. Anyone searching for a compatible turbocharger by vehicle, engine code, or OEM reference will find the units matched to this motorisation here, alongside details on the geometry, the cartridge, and the core deposit that applies when the worn unit is returned. It is built for readers who already know their engine, not just their car model.

Each reference in this range is selected for its match to the 320d 150 hp engine code and its OEM equivalence, not for its position in a wider catalogue. The two units listed here are the ones currently available for this motorisation, and each one specifies its variable-geometry design so a garage or a hands-on owner can confirm fitment before ordering, including for cross-border DACH orders.

Professional uses by trade

A turbocharger failure reads differently depending on who is looking at it. The following list sets out how each type of buyer typically approaches the 320d turbocharger exchange, from a garage diagnosing a fault to a driver trying to identify the correct reference before ordering.

• Independent garage: Cross-references the engine code and OEM number against the customer's 320d before ordering a matching turbocharger for standard exchange.
• Independent garage: Checks whether the failure symptoms point to the turbocharger itself or to a related component before recommending a replacement.
• Stranded motorist: Searches by vehicle, engine, and power output after noticing a loss of power, smoke, or a whistling noise while driving.
• Stranded motorist: Looks for a straightforward exchange process, including how the core deposit and the return of the old part work.
• DIY enthusiast: Compares the CHRA cartridge and variable geometry specifications against the original part before ordering a 320d turbocharger exchange.
• DACH buyer: Checks the OEM reference and engine code, then confirms the core deposit terms before ordering a cross-border 320d turbocharger exchange.

Range comparison

The table below lists the two turbocharger references currently available for the 320d 150 hp motorisation, each intended for standard exchange and matched to a specific use case and packaging format for garages and individual buyers alike.

How to choose

Choosing between these references comes down to a handful of practical checks rather than brand preference. The points below help garages and individual buyers confirm they are ordering the correct turbocharger before committing to an exchange.

1. Confirming the engine code and power output against the vehicle documentation before ordering, rather than relying on the model name alone.
2. Cross-checking the OEM reference and its known equivalences to make sure the unit matches the original turbocharger fitted to the engine.
3. Understanding the core deposit terms and how the worn turbocharger is returned once the exchange unit has been fitted.
4. Checking whether the failure symptoms, such as loss of power, smoke, or a whistling noise, match a turbocharger fault rather than another cause.
5. Verifying the variable geometry design and the CHRA cartridge specification so the replacement behaves as the original unit did.
6. Arranging for the mounting to be carried out by a qualified professional, since fitting a turbocharger involves precise engine-specific procedures.
7. Reviewing the warranty terms that apply to the exchange unit, since these are confirmed at the time of purchase and vary by reference.

Storage & logistics

A turbocharger exchange unit should be kept in its original packaging until fitting, with the oil inlet and air passages left capped to keep out dust and moisture. Garages ordering several references at once benefit from storing each unit separately and labelled by OEM reference and engine code, so the correct part is picked without cross-checking again at the point of fitting. The core deposit process also has a logistics side: the worn turbocharger being returned should be drained and packaged in a way that limits further damage before it reaches the exchange circuit.

Since 2026, our team has built this range around one principle: a turbocharger reference is only listed once its engine code, OEM number, and power rating have been checked against the motorisation it is meant to replace.— autoKUR team
