Our fleet: Audi A6 Avant - July 2014



As a Euro6 compliant vehicle, the Audi A6 Avant is the first car we’ve had as a long-termer that requires AdBlue.

What does this mean? Possible not much for Fleet News, as our cars generally return to the manufacturer after six months with between 6,000-8,000 miles on the clock. For a fleet, it means rather more.

Audi says that the 17-litre AdBlue tank will need refilling on average every 10,000 miles, depending on driving behaviour, engine temperature, vehicle loads and towing (although the owner’s manual recommends a top-up is included with the 20,000-mile service).

Fleets have two choices: purchase AdBlue in 1,890ml bottles with a filler neck valve at £5.50 excluding VAT. Audi recommends filling with 5.7 litres of AdBlue, equating to three bottles, at a cost of £16.50.

Alternatively, Audi dealers sell five litre bottles costing £5.69+VAT but they do not come with a filler neck valve. Contents have to be loaded into a filling device at a labour charge of 12 minutes if part of a service or 18 minutes if it’s a standalone job. The actual cost will vary by region, advises Audi.

At an hourly labour charge of £60, for instance, this means another £5 if part of a service. The total cost via a dealership of just over £10 will be carried out potentially eight times over an 80,000 operating cycle - £80 to add to the SMR costs.

Not much, perhaps, but any additional cost is unwelcomed.

Fail to fill the tank and the car will go into limp-home mode. No long-term damage will be done, but it’s obviously ill-advised to ignore the dashboard light when it illuminates.

Audi says it is working on a fixed price offer for AdBlue, suggesting the price will reduce as Euro6 vehicles become more commonplace. Plus, every manufacturer choosing the AdBlue route to compliance will be in the same position. Costed out, this could add up to £8,000 for a fleet of 100 over a full lifecycle.

Meanwhile, the A6 remains a charming companion offering superb road manners, a comfortable drive and reasonable efficiency. We’re still stuck in the low to mid 50s for fuel consumption but that’s more down to driving style as anything.

Audi’s Sportback moniker is usually a byword for added practicality. But, with the latest Q3 Sportback, that simply isn’t the case.

    I have an A6 Avant Ultra and just done over 5000 miles when the Adblue warning Light came on. I live close to a garage which sells adblue, so I thought, not a problem to go to the garage and top up. The nozzle fits perfectly, but after about 20 minutes I had managed to add 5 litres to the tank. It did not matter how soft I tried to add the fluid it permanently cut off the flow. There appears to be a flap which prevents using a normal filler pump. A total of 5 litres at 55p a litre, £3.00. How can Audi justify preventing users from using a normal adblue filler pump, so as they can charge exorbitant prices with a specific filler cap?

    Yes this seems unjust, Ad lie from the pumps is .60p per litre yet up to £1.40 a litre from bottles. There is a device that has a magnet that allows delivery from the pump filler but at £20.00 it's an unnecessary expense which seems to exclude cars from using these pumps. (So unfair). The other thing I don't understand as a high mileage driver (30 k per year Audi A6 ultra). I require 17 litres every 6000 miles. With moderate motorway driving. So why have Audi fitted an Adblue filler cap that requires a wrench to Undo ? Which means I have to retrieve the tyre wrench from under the boot when it is usually loaded with equipment, such a pain..
