Low fuel pressur despling in my car what i have yo do
If it just came on that there is low fuel pressure the first thing you should check is if there is a fuel filter(some vehicles don't have a changeable filter) and change it because they can plug up and restrict fuel flow over time. If the low fuel warning doesn't go out get your fuel pressure checked. Usually about 1/2hr charge in most shops.
How it's done on BMW X6:
1 Scan the computer system in the car for trouble codes.
2 Inspect fuel pressure regulator for leakage and proper operation.
3 Inspect for any broken vacuum lines.
4 Remove and replace fuel pressure regulator if it is bad.
5 Change the engine oil and filter if the oil is found to be contaminated.
U need to check the fuel flow to ur engine of bmw. monitor the flow.
