Porsche Panamera (970) 3.0L V6 TDI Engine – Complete 300 HP CWJ Power Unit

Complete, Low-Mileage Audi-Sourced 3.0L TDI V6 Engine for Porsche Panamera Diesel.

This listing is for a complete, original 3.0L V6 turbocharged diesel engine, engine code CWJ (Porsche designation), producing 300 horsepower. Removed from a 2014 Porsche Panamera Diesel (970) with a low 89,197 km (~55,425 miles), this fully dressed assembly is the high-performance diesel variant used exclusively in the Panamera. It offers a direct-fit core for engine replacement, combining Porsche dynamics with Audi-sourced TDI efficiency and torque.

Product Overview & Core Specifications

• Engine Code: Porsche CWJ (Audi counterpart: ~CGLC, CAPA)

• Displacement: 3.0L V6 Turbo Diesel

• Power Output: 300 HP (221 kW) / 650 Nm

• Mileage: 89,197 km (~55,425 mi) – Low

• Year: 2014

• Condition: Used, Complete & Dressed Assembly

• Key Feature: High-pressure common rail injection, twin-turbo (sequential) configuration, AdBlue (SCR) system for emissions.

Vehicle Compatibility & Fitment

• Exclusive Application: This engine is designed specifically for the Porsche Panamera Diesel (970, 2011-2016). It is a direct bolt-in replacement for this model.

• Related Audi/VW Engines: While based on the Audi 3.0 TDI, the Porsche version features unique tuning, specific turbochargers, ancillaries, and engine mounting. It is not a direct plug-and-play for an Audi A6/A7/Q7 without significant modification and re-tuning.

• Complex Electronic Network: The engine is governed by a Porsche-specific Engine Control Unit (DME) that communicates with the Panamera’s PDK transmission, Porsche Traction Management (PTM), and all chassis systems. This deep integration makes swaps into non-Panamera vehicles a major, expert-level challenge.

What’s Typically Included & Condition Assessment

This is a complete, dressed engine as removed. It should include:

• Complete V6 long block with twin turbochargers and intercoolers.

• Intake manifold (with swirl flaps – a known maintenance point).

• High-pressure fuel pump, fuel rails, and injectors.

• Complete engine wiring harness and the Porsche DME (ECU) – VIN-coded to the donor Panamera.

• All sensors, EGR system, AdBlue dosing module, and ancillary brackets.

• Condition: Low mileage is favorable, but TDI-specific due diligence is required:

  • Service History: Request records, especially for the timing belt (critical, interval ~210,000 km but check age), AdBlue system health, and oil changes.

  • Swirl Flaps: The intake manifold swirl flap mechanism is a known failure point. Inquire if it has been inspected, repaired, or deleted.

  • Turbo & DPF: Check for proper operation of the twin-turbo system and ensure the Diesel Particulate Filter (DPF) is not catastrophically clogged.

  • Leak Inspection: Common leak points include valve cover gaskets and the vacuum pump seal.

This is a sophisticated, high-torque diesel engine deeply integrated into the Panamera’s systems. Success depends on confirming its mechanical health (especially swirl flaps and turbos) and having a clear, expert-led plan for DME integration, whether for a direct replacement or an ambitious swap project.
