The 2005 B7 Audi A4 Quattro has a fuel capacity of 15.4 UK Gallons / 18.5 US Gallons
it may be in fuel tank,but first check fuel lines and see if it's along the frame. they seem to go out.
takes about an hour you access from under rear seat.. unit fitted to fuel tank...check FUEL PUMP RELAY first ....
It is under the car near the the driver's-side rear tire. The fuel filter is right there, too. I own such a car and am about to change the pump, so I am glad this car dates back to before they put the pumps in the fuel tank. Mine is the Audi 90 Quattro, so the fuel tank is behind the rear seat and can be reached either through the trunk or by removing the rear seat.
On a 2001 Audi TT Quattro the fuel filter is located forward of the fuel tank, in the right rear wheel well area. The fuel line clamps are a bit tricky. The change will improve performance. The owners manual does not even list changing the filter. But do it! I used a Fram, and it fit perfectly. Good luck.
it is in the fuel tank
I can't tell you for sure because I never had an Audi, but since it is electronically fuel injected it would have an electric fuel pump... If your pump is not totally dead, you should hear a humming sound when you turn the key forward a click (not to start the car just to accessory) that sound would be your fuel pump turning out and pumping gas to your engine... My guess would be that the fuel pump is in the gas tank... if not, just follow the fuel line from the tank towards the engine and somewhere between the two will be a fuel pump... Hope this helps!
If It is the temp. sensor and not the thermosat I believe it is the bottom of the coolant tank. I thimk you have to buy a new tank.
Passenger side in front of the wheel well. On the quattro it is mounted veritical instead of horizontal on the front wheel drive. If you endeavor to replace it, know that you have to loosen a couple of bolts on the fuel tank and wedge a 2x4 between the fuel filter to get a metric wrench on the fuel strap.
Mounted on top and inside the fuel tank.
