Just go my high up yesterday and taken out at a range of speeds from 20 in speed bump zone, to 55 on an A road. I notice accerating even at just 2000 rpm that it is very noisy, though as soon as you ease off the pedal is quietens down a lot. Is this normal? I had an aygo until just over a year ago so I am used to 3 cyl engines. It wasn't that bad. Is it something that decreases with running in? Or should I take it back to dealer.
