ENGINE LIGHT WILL NOT GO

[vickymac]

Hi everyone,

I have a BMW 320D 2 litter, 2010. The engine light will just not go off for like 5 months now. I have put soooo much money into this car and i went through so many mechanics and I honestly do not know what to do anymore.

I have changed crankshaft pulley, new belt, new glow plugs, cleaned EGR, new water pump, injectors changed, cleaned exhaust.

Now the codes are the following:

4560 Rail pressure
41E7 Oxygen sensor
4CF3 Exhaust Back Pressure Sensor

What else do I have to buy or do so the engine light goes of my dashboard? After every visit mechanic turns it off and it comes back on in couple of hours.
