Hi guys,
I have had absolutely no problems with my Bmw 320 2010 for quite some time,
However only recently I have heard a slight whirring while driving and goes in tune with the revs of the engine (low revs no whir, high revs louder whir. After another month or so my fuel pump warning light has come on.
The car in my opinion hasn't lost any power but there is definatly a noise coming from the engine bay.
I have had a obd reader check the fault and attempted to reset it but has come straight back on.
What would you suggest to do to try and resolve the problem as my current thought is that these could be the following issue:
Injectors
Fuel filter
Hpfp
Fuel pump next to tank
Faulty sensor
Can anybody help as a hpfp is not cheap!
Thank guys!
