Looking at all the Alhambra 184 dsg results they seem in line with the crappy 30mpg I get from mine and 80%+ of my driving is at 70mph on cruise, if I reduce that to 65 or even 60 it gets worse, only starts to improve once it drops to around 50(long average speed sections etc).
VAG Offical figures say about 52mpg, liar liar pants on fire!
