Mulliner Posted October 20, 2017 Share Posted October 20, 2017 Hi New to this forum, thought id see if anyone else has experienced this. I must also point out a friend of mine with the same car has just complained to the dealer after 20,000 miles for the same issues. This is the letter written to the dealership below. Hope you are well, car is lovely and great for the long journeys…….. but I have been concerned about the MPG and having spoken to other Audi drivers there does seem to be a huge difference between whet is stated by Audi and what the car can get anywhere near delivering. When I looked at the specs before going ahead this is what Audi specified. EC Urban 47mpg EC Extra Urban 59mpg EC Combined 53.3mpg I have done different driving styles over long distances using Eco/comfort and Auto modes and it would be a pleasure on a 200Mile drive to get anywhere near URBAN in Eco mode but in eco mode driving like an absolute saint you can scrape 40MPG I was expecting this to be Urban and to on the longer journeys to be getting 50+ especially when driving in such a way. A simple calculation on 20,000 per year filling up at supermarkets doesn’t fill me full of glee especially when I was expecting the engine to perform better. 20,000 miles per year £1.14 per Litre achieving the current combined 38MPG = 526.31 Gallons x 4.54609 = 2392.65Litres Annual Fuel Cost £2727.62 20,000 miles per year £1.14 per Litre achieving the Audi quoted combined 53.3MPG = 375.23 Gallons x 4.54609 = 1705.84 Litres Annual Fuel Cost £1944.66 The difference could be £782.96 per year and over the three years £2348.89 I have not quoted the top efficiency ratings for the MPG and this seems horrendous. When driving the A5 this was getting very near without switching myself into saintly driving mode! I have consulted with other A6 drivers of the same engine and they inform me this model does seem to have issues with the MPG capabilities (even when run in), I am concerned the information stated by AUDI is misleading and at my cost! Additional notes; I have kept a log whilst trying trying different car settings, fuels, driving styles (from saintly to enjoying the car!) and the variation is negligible. I have noted from reading the forum that the fan going off when stopping the car for a while and high idling revs is also a thing, can anyone enlighten me about this. History...... last 3 cars 5 series's 520d - 530dM-Sport - 530d M-Sport 2nd model when driven saintly was around 500+ to a tank driven Urban 430, the last model was 500+ urban and 6-700 with distance and everyday use. On a recent journey - Shrewsbury - N. London - Peterborough - Bourne - Shrewsbury 38MPG! in the A6 Quote Link to comment Share on other sites More sharing options...
Mr Filipov Posted November 20, 2017 Share Posted November 20, 2017 Hello, New here, but might be able to advise. I currently do not own an Audi, but I am fairly certain the process is the same across the board. The fans running and higher revs while stationery would be an active DPF regen. Whilst this is happening the car will be using more fuel as well due to dumping extra in the cylinder to get the DPF up to temp to burn off the soot. If you do notice it running, it is recommended to keep driving while this is done in order to allow the regen to complete. If not, it should resume the next time parameters are met in order for that to run. Many thanks Ivaylo Filipov Quote Link to comment Share on other sites More sharing options...
