Help n47 intermittent fuel issue

Help!!!

2010 BMW 320D EFFICIENT DYNAMICS

So I’m having intermittent fuel issues that cause the limp mode light to come on and the engine to sometimes cut out. When I then come to a stop and try to start the engine straight away on the button it cranks but doesn’t start. I then push the button again and it starts straight away and drives for a bit then the process repeats. All the while the engine jerks every so often and then cuts out.
I changed the in line fuel filter about 10 days ago and since then no problems until this morning which is when the above started happening again. I’ve got a Carly OBD scanner and have provided pictures of the codes it is throwing up.

For reference I’ve only owned the car a month and the previous owner did not mention these issues but did provide me with paperwork of the previous work it has had done to it. This includes

1 new EGR valve on 30/04/2024 at 78348 miles

1 New inlet manifold and breather hose
1 new Mass Airflow sensor on 05/06/2024 at 78618miles
(These new parts above were supplied and fitted by and independent garage)

And then the car was taken to BMW where the following actions were taken
(20/08/2024 78778 miles)

Clean Inlet manifold ports
1 new EGR valve
ECU reprogramme

Any ideas or suggestions on my next port of call for fixing this car, when it’s right it’s a superb car to drive but I can’t trust it and that kills me inside. Thanks for reading 😊

(Also as another point of reference the car comes with full service history)

Put each code into google and have a good look at a fair few results to see if there's a common theme.

I does seem like an obvious fuel supply issue. If you have live data, try read the fuel pressure and see if it fluctuates.
