A full rebuilt Audi A8 40 TFSI - 60 TFSI S8 W12 engine typically costs between £5,000 and £15,000+ for supply only, depending on whether it is a 3.0L V6, 4.0L V8, or 6.0L W12.

• Prices vary based on the specific engine code (e.g., CGWB, CEU, BXB).
• Supply and fit packages will add specialist labour rates, usually £780-£1,430.

Early warning signs include coolant leaks under the vehicle or a distinct sweet smell from the engine bay.

• You may also experience an illuminated engine management light or the engine running hotter than normal.
• If ignored, coolant loss can lead to catastrophic overheating.

For D3/D4 models valued between £8,000 and £25,000, a full rebuild is highly financially viable for well-maintained examples.

• A reconditioned or rebuilt unit restores flagship reliability and comes with a 12-month warranty.
• This is significantly more cost-effective than purchasing a new vehicle.

A standard supply and fit procedure for the 3.0L to 6.0L TFSI/W12 engines typically takes 3 to 5 working days at a specialist workshop.

• This includes the physical swap, complex ECU coding, and a thorough road test to ensure all premium systems are functioning correctly.

Both are 4.0-litre twin-turbocharged V8 petrol engines, but the CVPA is the high-output S8 variant.

• The CVPA features upgraded internals, larger turbochargers, and revised ECU mapping to produce 520hp, compared to the CEU's 435hp. They are not directly interchangeable without significant modifications.
