This morning I ventured under the dash and had a closer look at the warning light cluster which, on the 4/4 sport, is a printed circuit with leds. Immediately I saw that the wire ribbon connections to the board were scuffed - rubbing against the dashboard. I cleaned them with a cotton bud and, success, no more glimmering lights. Before reattching the board I stuck some electricians tape over the connections to provide some cushioning. Just a warning, beware that the printed circuit connections will rub on the dash.
