Default Engine problems with 318i

Hi. I have BMW 318i with M43 engine. I have engine check light on. It feels that car lost performance. Idle is jumping from 0.5 to 0.9rpms. I have changed o2 sensor, pcv, pcv hose(it was cracked), maf. Bmw scanner showed : "8D [141] Oxygen-sensor control, control limit" and "AB [171] Check, fuel supply system". Inpa showed : "141 lambda regulation control range block" and "171 Pruefung Kraftstoff-Versorgungssystem". I hope that you will help me to identify what part of my car is broken, because I will not pass car check-up.

But if that would be because of fuel pressure wouldnt it work fine using other fuel type? What I mean is that my car car LPG and petrol fuel systems.

Well the o2 sensor code or lambda code means that it cannot add anymore it has passed its limit and the other suggest fuel issue which tells me your car either has a huge air leak or not enough fuel
