wierd noise

[Raz316]

I am getting a wierd buzzing noise from the underside of my car towards the rear. As far as I can tell it isn't the exhaust and it sounds mechanical.

Anyone experienced this?

Ta!

Its a 2 door 1991 316i

maybe the diff?

lets say it is, i take it id have to get a new one? Will it be expensive/worth it for a car that is pretty old :/

Fuel pump?
Under the back seat on the drivers side!

thanks, Im not mechanically minded... at all. So how would I check it? (though admittedly I havent even had a proper look under the car yet because im stuck at uni)

To check if its the pump,lift the base of the back seat up and start the car,if its noisy then its on its way out!

[Raz316]

that'd make sense actually because it is actually noisier in the car than out (sorry for not mentioning)

fuel pumps expensive?

[eko]

if it is the pump(common problem)then you should get one in the parts for sale section,expect £20ish for a good replacement!

roooock, thank you.

Out of interest how safe is it for my to drive my car like it is? Is there a chance it will all of a sudden stop?

[Raz316]

Just to confirm. It was indeed the fuel pump

sorted!
