engine hesitation on light acceleration

2015 Volvo V60 D3 Diesel D4204T-9.
Any suggestions on this one, on light acceleration engine kicks or jumps, on hard acceleration everything is fine. No fault codes. It was suggested that the MAF sensor was faulty. It's strange I replaced the existing MAF sensor with a known faulty one the car runs perfectly but throws engine check light on, replaced the faulty MAF sensor with a new one and the car starts hesitating on light acceleration, with no fault codes I don't know which avenue to go down so I'm open to any suggestions/ help on this one.

Behaviour that you described sounds to me like O2 sensor problem. At least, that's how it started with my car. In the beginning, only light acceleration was jerky, later I started to feel it under havier acceleration.
