I'm getting used to my new A4 Black Edition, however unlike the A1 I drove previously, I can't seem to find a way of turning off the efficiency messages in the DIS or the gear change indicators. The reason I want to is because I like the 'efficiency mode' display on the DIS as it has a lot of useful figures all on the single screen (Range, Current MPG, Average MPG etc). However, the gear change indicator is shocking (it wants me to change up FAR too early, and even into 6th at really low speeds) and it keeps coming up 'Observe gear change indicator' messages which I keep ignoring or pressing the button to dismiss. Is there any way of turning this feature off? It's REALLY annoying!
