I stayed on the highway on Thursday, with my beautiful 1 Series BMW built in 2009, 190000km.
For some time now, the engine control light went on, but then went out again and again while driving.
By Thursday, my car had stopped working and suddenly had no performance. The car started at the beginning but was very restless.
The following error codes were displayed:
4BDC - fuel pump pressure control - permanent
4560 - Line pressure monitoring, supply line deviation - permanent
4570 - Line pressure monitoring, supply line deviation - permanent
4610 - Line pressure monitoring, pressure deviation - permanent
49A2 - Message (A_TEMP_RELATIVZEIT, 0x310) - Permanent
483D - Function, throttle valve actuator - Permanent
4630 - Line pressure monitoring, pressure deviation - permanent
The fuel filter was then replaced, but was unsuccessful, since then it has not been possible to start.
Some time ago 2 weeks ago the car got a new battery that was also registered.
Can someone help me what can be there or what can be checked first to determine the possible defect?
I have a Delphi vehicle diagnostic device that I can use to check some things, but I don't know where to start.
I appreciate your help!
