Last month my car(98 A4 1.8T, 250k miles) had a no start condition because of a bad fuel pump. I then replaced it with a new Siemens VDO pump and car is running fine now.
But today after starting the car there was the same whining noise coming from the back side which I used to get in last year when car was running with a bad fuel pump. Fuel was very low in the tank (probably 1 gallon) and I was going to fill the gas when this happened. The whining noise lasted for about some 40 seconds and then went away.
Is this normal?
I know that fuel pump makes a sound when we turn on the ignition, but this was happening after starting the car. Also, I feel that the noise fuel pump makes when turning on the ignition is very loud too...
The fuel filter was last changed 60k miles ago.
