It sounds like you bought an audi. These cars are not cheap to have worked on, and if the car was as neglected by the previous owner as it sounds you will continue to have problems. Can you work on cars? Where do you live?

The fuel pump is common, probably caused by a clogged filter so replace that at the same time. The valve cover gasket is common too, mine went at about 60k miles.

How many miles are on it?

 

i think it SOUNDS LIKE he bought an Audi from someone who wasnt really taking care of the car!!!
where are u from?

 

oh and, if your fuel pump is making noises, it is better to change it ASAP cuz you might get stranded!!!
But here is some good news.... usually its your filter that makes those noises, it is much cheaper to change it than a fuel pump

 

Welcome to the finer things in life!

 

amen !

 

Ok, let me try to tackle this one issue at a time, your fuel pump is more than likely fine. Start by changing the fuel filter (approx. $60 for parts) and if the humming goes away you are good. Change the fule filter first because if it is in fact your pump the filter will need to be changed anyway and a clogged fuel filter shows identical signs of a bad fule pump. FYI, the fuel filter should have been changed around 40K miles.

For your alternator, I would say go in and make sure the wires are connected correctly and solder and shrink wrap them for good protectioon but the safest route is to get a new alternator harness and it probably won't be cheap but I will try and do some research for you. A picture would help a lot.

The leak from the valve cover is most likely the gasket, also a cheap fix. If your crankshaft seal is shot (which is unlikely) then your motor is probably toast. Are you sure that seal is leaking?

All of your other electrical problems could be coming from the alternator so get that fixed first and that may cure everything else. As far as your window, it could be the window regulator which isn't too bad to fix, just keep the window up for now you really don;t want to get it stuck while it is down.

Where are you located, I could possibly help you with most of these problems (alternator is the only iffy one, fule filter, timing belt, valve cover gasket and window regulator are a go)

 

i live on Kent island in Maryland right by the bay bridge i can work a little bit on cars i can figure out how to do it but not diagnosing

 

Check with your dealership and run the VIN or go to the DOT website. There is a recall on the fuel pump and filter. Take it to the dealership and they will change it at no charge.
