Hi everyone, my car 2014 m135i (pwg) has this issue since i bough used at 115 km. No one seems to be able to fix this issue for me and I kind of lost hope.

I been seeing this since the car was stock, the car came with some exhaust brand but I dont think it is related to this issue. Since then I have tuned the car with bigger intercooler and catless downpipe but i kept the stock intake.

Things i have done changed or fixed
- cleaned maf sensor
- replace valve cover, and oil pan gasket
- replaces spark plugs
- replaced ofhg, gear oil cooler, water pump, cooling system. that was due a milkshake incident.
- upgraded rod bearing
- upgraded hpfp to b58u

The car is running now mhd stage 2+, even without the tune the car will pop this error code randomly. I noticed that everytime is flash the car and fuel trims reset the car will have rough shakes and might even turn off.

This will go away as soon as maf sensor activate and the STFT will climb to 25%. after like few days of driving the LTFT will catch up to avg of 25% and the car wont shake with turning cold engine on.

My last attempt to fix was yesterday when I took the car for a smoke test. The technicians seemed clueless and didnt find any sort of leak, right after that they had discussion with the owner of the shop who is a tuner and he decided that it was the LPFP somehow, tbh im not convinced and I just think he wants to sell more tuning parts that I dont need. The car right now is approaching 150k km, could it be that? the rail pressure seems to be fine to me based on the log below

The car otherwise run really good once the ltft is learned but the check engine is super annoying and makes me feel like im destroying the car

I have the data log below

If they couldnt find it with smoke test what could it be?

Thank you
