Update on the minor ‘lumpiness’ issue at low speeds when easing off throttle. Following NosherN’s comments I left the car in ‘Comfort’ mode today until we joined the motorway when I selected EcoPro. No lumpiness at all, so it might well be to do with EcoPro at low speeds / rpm. As an aside, now up to 43.5mpg on the first tank of fuel. 500 miles since I last filled up and I still have a remaining range of 53 miles. For a powerful 2.0i petrol auto with 4WD I find that incredible.
