Audi A6 Avant Running Costs

Overall Rating:

Running Costs

Our Rating:

With an efficient mild-hybrid system as standard across the range, the Audi A6 helps by saving on running costs, but it doesn’t have a very eco-friendly track record when it comes to CO2 emissions compared to other estate car alternatives.


The entry-level 40 TDI diesel model is the most cost-effective option in the A6 Avant range. It has the ability to return 60.1 mpg and emits a reasonably acceptable 124g/km of CO2 making it the most popular company car in the range. On the flipside, the punchy 50 TDI diesel engine is not so efficient as it returns 48.7 mpg with whopping CO2 emissions of 150g/km.

Unfortunately, the petrol engines can’t match the fuel economy of its rival diesel outputs. Although it might be smooth, the 45 TFSI petrol engine returns a thirsty 42.8 mpg while emitting a not so eco-friendly 152g/km of CO2.

Let's be honest, the big bertha 55 TFSI petrol engine is not bought with fuel economy as a top priority. The nimble output returns a measly 29.7 mpg as well as emitting a distressing 169g/km. 

Insurance Group

In terms of insurance groups, the Audi A6 Avant entry-level Sport trim ranges between groups 30-40.

The 40 TDI belongs to group 30E, while the 50 TDI is up in group 40E.

On the other side of the fuel spectrum, the 45 TFSI Sport trim is in group 35E whereas the 55 TFSI Sport is in 39E.

As a brand, Audi reliability ranked surprisingly low on Reliability Index’s manufacturer rating. Audi placed 34th out of 40 manufacturers with a reliability index of 195. 

The UK Reliability index takes into account all factors of a repair, the cost of the parts and the frequency of failures. The average of all cars is 100 - anything rated higher than 118 indicates that the car is less reliable than average.

The A6 Avant scored 188 with average repair costs totalling £541.75. Although the number of reported reliability issues on the A6 Avant are minimal, there have been concerns regarding phone connectivity to the infotainment system as well as annoying rattling noises from interior trims


The three-year/60,000-mile Audi warranty including roadside assistance is pretty bog standard. You can upgrade to Audi extended warranty which covers you for four years/75,000 miles for £245 or five years and 90,000 miles for £545, which seems a bit steep when you’re already paying a premium price. 

BMW and Mercedes also offer a three-year warranty, but with the added perk of unlimited mileage, so that’s something to keep in mind if you are keeping your options open.

A manufacturer’s warranty is important when it comes to choosing a lease. That’s because a warranty states that if anything goes wrong with a car during a period of time, it is the responsibility of the manufacturer to put it right. If the fault happens outside of this period of time, and you don’t have a maintenance package, you’ll be responsible for fixing the problem.

Audi offers three levels of scheduled servicing and maintenance as part of their ‘Complete Plan’.

  • The biggest saver is Service, which covers all your services within the first three years. 

  • The Service and Maintenance option adds further cover for engine, suspension, gearbox and brake components. On top of this, you’ll also receive three years’ breakdown cover.

  • The premium plan - Service, Maintenance and Tyres also includes replacement tyres, wheel alignment and puncture repairs.

There are also two types of service schedule available - Fixed (9,000 miles/1year) and Flexible (up to 19,000 miles/2 years). Flexible is recommended for longer distance drivers, while fixed is better suited to lower-mileage drivers.
