I've had my A160 CDI for about four months now. Most of the time, provided I keep the transmission in "S", it's fine. However, sometimes I find I need to pull out smartly into a road that has sporadic gaps in traffic. I find that the car seems to be a bit sluggish, sometimes resulting in me having to stop and wait again.
Is there anything I can do myself to improve this? Is it a fault? Or is it something I just have to get used to?
