Hi all, just been to the shops with my lad and he commented on one of my posts. He asked what the whirring sound was coming from the back of the car ? now I'm thinking could it be the fuel pump ?? please help It only seems to be there around 30 MPH but tends to go over this speed  2007, HSE, Cairnes Blue, Factory tints, Love it !!!

If you can hear it when driving down the road then it's more likely a wheel, dif or prop centre bearing than a fuel pump. Is it speed related or does it change with the gears ? 2008 G4 RRSport TDV8 current

Thanks for the reply, It starts light whiring about 30 mph then vanishes as you go faster, but the annoying thing is when you come back down to 30 ish its the same pitch and oscillation until the vehicle stops, but it's not engine related as stationary revs do nothing for it as it's not there. The other ideas I had was could it be the park brake rubbing or even the gearbox playing up, but it drives smooth as silk so stuck on this one..If it was a bearing would it not speed up and down with speed, as this does not ?  2007, HSE, Cairnes Blue, Factory tints, Love it !!!

Hi noise will vary with speed as you say to some extent depends how bad they are. If only starting to go above 30 if rear bearing your leaving the noise behind, best thing is to get it checked out

Hi Joe, no mate not there in neutral, but its deffo getting louder. I thought of putting it on a rolling road to see if this helps identify it, what a pain eh ! any ideas much appreciated  2007, HSE, Cairnes Blue, Factory tints, Love it !!!
