Bentley GT GTC Flying Spur Turbocharger Left 07C145061AJ

part number 07C145061AJ identifies the Left Hand (LH) turbocharger for the Bentley 6.0L W12 twin-turbo engine. This specific unit is common in the first and second generations of the Continental GT, GTC, and Flying Spur (typically covering model years from 2004 to 2013/2015, depending on specific supersessions).

1. Technical Specifications

• Manufacturer: BorgWarner (3K – Schwitzer).

• Turbo Model: K16 (specifically the K16-2480DGB series).

• Configuration: Integrated manifold and water-cooled bearing housing.

• Side: Left (Driver’s Side on LHD). This unit is mirrored and not interchangeable with the right-side unit (07C145061AH).

2. Compatibility & Supersessions

This part number has been updated by Bentley several times. If you are sourcing this for inventory or a repair, the following part numbers are functionally equivalent or related supersessions:

• 07C145061AJ (Standard OE number)

• 07C145061AB / 07C145061AE / 07C145061P / 07C145061R (Previous versions/Supersessions)

• 07C145061AJX (Factory remanufactured version)

3. Critical Installation Warning (The “Engine Out” Job)

Replacing a turbocharger on the Bentley W12 is one of the most labor-intensive tasks in the automotive world.

• Service Position: This is a 5/5 difficulty job that requires the complete removal of the engine and transmission assembly. Labor times are typically quoted at 30–40+ hours.

• Oil Starvation: The #1 cause of failure for the 07C145061AJ is clogged oil feed strainers.

  • Pro-Tip: You must replace the oil feed lines and the internal mesh strainers at the same time as the turbo. Installing a new turbo without replacing these lines often results in the new unit failing within weeks due to oil starvation.

4. Component Identification for Inventory

If you are verifying a used unit, look for the BorgWarner/3K blue or green tag on the compressor housing. It should show:

• BW Part Number: 53169880018 or 53169700018.

• Note on Condition: Check for “Shaft Play.” A small amount of side-to-side (radial) play is normal for journal bearings, but there should be zero in-and-out (axial) play.
