that's strange as mine is droning exactly like op says. keep my dct on 2 lines and power mode. it drones all the time in city driving, from 1500 to 2500 or so. after 3000 is quiet. keeping with all settings at max - 5 lines, max power in m mode there is less droning as car tends to accelerate faster and avoid those rpm's. also if i shift manually can avoid droning or keep to minimal. however, never use manual shifting.
damn the crisis, i should take the amuse ericsson. wait the clips from manilla guy, if it sounds as it looks, will throw this away and start saving for the real thing.
hope to be able to switch to p car in the autumn, if not will also go for hre+brembo gt.
