EA898 or Audi V8 TDI engines

Diesel engines of the EA898 or Audi V8 TDI range were first introduced in 1999 and have since been installed on the flagship models of the German concern, such as the A8 sedans. This family also usually includes a 12-cylinder diesel engine, which was installed on the Q7 crossover.

Diesel engine 3.3 TDI

In 2000, a V-shaped 8-cylinder diesel unit appeared on the restyled A8 D2. This engine had a cast iron block, two aluminum DOHC cylinder heads with hydraulic lifters, a timing belt drive and a pair of Garrett variable geometry turbochargers with an intercooler. Also, this engine was equipped with a Common Rail fuel system manufactured by Bosch.

In the first line there was one power unit with a volume of 3.3 liters and it was produced for only two years.

3.3 TDI:

  • AKF (225 hp / 480 Nm) for Audi A8 D2.

Diesel engines 4.0 and 4.2 TDI

In 2003, a 4.0-liter V-shaped 8-cylinder diesel debuted on the Audi A8 D3. Its main difference was the timing chain drive and intake manifold with swirl flaps. However, this engine was produced for only two years and gave way to an updated 4.2-liter engine. In addition to increasing the working volume, the manufacturer upgraded the problematic timing chain, installed a new Bosch Common Rail fuel system with piezo injectors and other turbines.

We know of one 4.0-liter engine and seven different 4.2-liter powertrains.

4.0 TDI:

  • ASE (275 HP / 650 Nm) for the Audi A8 D3.

4.2 TDI:

  • BMC (320 HP / 650 Nm) for Audi A8 D3;
  • BVN (326 hp / 650 Nm) for Audi A8 D3;
  • CDSB (351 hp / 800 Nm) for Audi A8 D4;
  • CTEC (385 hp / 850 Nm) for Audi A8 D4;
  • BTR (326 hp / 760 Nm) for Audi Q7 4L;
  • CCFA (340 HP / 800 Nm) for Audi Q7 4L;
  • CKDA (340 HP / 800 Nm) for VW Touareg 2.

In addition to the Volkswagen and Audi models, this engine was installed on the Porsche Cayenne under the MCU.DB index, and in a special modification with twin turbocharging, which developed 382 hp and 850 Nm.

Diesel engine V12 TDI

The 6.0-liter diesel engine was created for the Audi R10 TDI racing car for the 2006-2008 seasons, but after the end of its sports career, it was installed on the Audi Q7 crossover for several years. This motor has little in common with the V8 TDI, since it has a camber angle of 60° instead of 90°, however, in a number of sources, for some reason, it is referred to this particular line of power units. It also has an unusual timing chain drive with an intermediate shaft, a couple of powerful turbines and a particularly efficient Common Rail fuel system from Bosch with a pressure of up to 2000 bar.

There was only one modification of this engine with a capacity of 500 hp and 1000 Nm.

6.0 TDI:

  • CCGA (500 HP / 1000 Nm) for Audi Q7 4L.

Engine Audi AKF

The 3.3-liter diesel engine Audi AKF or A8 3.3 TDI was produced from 2000 to 2002 and was installed only on the first generation of the A8 sedan in modifications after its restyling. This is the only V8 diesel with a timing belt, the following versions were equipped with a chain system.

Engine Audi ASE

The 4.0-liter diesel engine Audi ASE or A8 4.0 TDI was produced from 2003 to 2005 and was installed only on our popular A8 sedan in the back of D3 before its first restyling. This V8 diesel had an unsuccessful timing design and quickly gave way to 4.2 TDI engines.

Engine Audi BTR

The 4.2-liter diesel engine Audi BTR or Q7 4.2 TDI was produced from 2007 to 2009 and was installed only on the first generation of the popular Q7 crossover before its restyling. A similar diesel engine under the hood of A8 sedans in the back of D3 has its own BVN index.

Engine Volkswagen CKDA

The 4.2-liter VW CKDA or Touareg 4.2 TDI engine was produced by the company from 2010 to 2015 and was installed only on the second generation of the Touareg crossover popular in many markets. A similar diesel under the hood of the Audi Q7 is known under its own index CCFA or CCFC.

Engine Audi CCGA

The 6.0-liter Audi CCGA or V12 TDi diesel engine was assembled only from 2008 to 2012 and was installed only on charged versions of the popular first-generation Q7 crossover. This power unit is the most powerful diesel that was installed on civilian cars.
