Question 1

Should I buy an Audi A6 2.0 TDI or 3.0 TDI?

Accepted Answer

The 2.0 TDI is enough for a front-drive saloon or Avant and, with fewer kW, pays less IPT and bollo. The 3.0 TDI V6 suits towing, quattro and long motorway runs, but check whether its power brings the superbollo.

Question 2

Which Audi A6 diesels pay the superbollo?

Accepted Answer

V6 TDIs above 185 kW, such as the 272 hp and twin-turbo BiTDI versions of the C7 and the 286 hp 50 TDI of the C8. The 2.0 TDIs and the less powerful V6s stay below.

Question 3

What are the weak points of the Audi A6 3.0 TDI?

Accepted Answer

At high mileage its timing chains can stretch, heard as a rattle at a cold start, and they are costly to replace because they sit at the back of the engine. Cars used mostly in town also tend to clog the particulate filter and EGR valve.

Question 4

Which diesel engines does the new Audi A6 have?

Accepted Answer

Two TDIs: one with 204 hp, front-wheel drive or quattro, and one with 299 hp and quattro, both with the seven-speed S tronic. Each comes as a saloon or Avant in Business, Business Advanced and S line trims.
