Loss of power

I have a 3 series 318d business edition 2010. It appears to have lost some power. Noticed more when laboured. Any help appreciated. No warning lights

    Morning Ian

    A little more information for us to make a best guess such as mileage, service history, and what kind of use (short journeys or Motorway) 

    With the limited information first step get the codes read you need a garage with Autologic as a minimum preferably a BMW specialist or if deeper pockets a BMW dealer.

    Loss of power could be MAF failing, EGR clogged, DPF needing regeneration, Turbo or turbo actuator, swirl flaps failing, sensor failed, Fuel delivery and filter. The list is long and the last thing you want to do is chase the fault changing parts that is a very expensive route to take.
