The car has been an excellent and reliable runner and has been very well maintained throughout my ownership. It is a particularly economical car for its size, with 60+ MPG easily achievable on longer journeys. Overall fuel economy is approximately 47 MPG, including regular short trips and shopping journeys. One of the main benefits of this car is its consistent maintenance history. The car has been serviced annually at approximately 9,000-10,000-mile intervals. The servicing has included: Engine oil and oil filter Air filter Cabin/pollen filter Fuel filter Timing belt with water pump This means the car has received regular, comprehensive servicing rather than simply occasional oil changes. The Audi A6 is a comfortable and spacious executive car, but the 2.0 TDI Ultra engine is also remarkably economical: 60+ MPG easily achievable on longer motorway journeys Approximately 47 MPG overall, including short local shopping trips It is an excellent car for someone looking for comfort, space and low running costs. The only reason I am selling the car is that I have recently purchased a newer Audi A6. The car has been an excellent runner and is being sold simply because it is no longer required. The mileage is 154k miles, which is reflected in the asking price. However, the car has been maintained consistently, with annual servicing every 9,000-10,000 miles. A genuine, economical and well-maintained Audi A6 with a strong recent servicing history. Viewing welcome for genuinely interested buyers.
