1. Lift out the bottom rear seat – Remove the baby seat clips then lift seat upwards, slide out of door and into the front of the car for safe clean storage.
2. Unclip the snap clip wires from onto of the rubber cover on seat base behind drivers seat.
3. Lift off the rubber cover and place safely to one side.
4. Disconnect the blue and black pipes, and place in a pot to collect fuel from pipes (shouldn’t be much)
5. Use hammer and long flat bladed screw driver to turn round the metal locking bracket type thing
6. Fuel pump is almost spring loaded so should pop upwards, lift out slowly allowing time for fuel to drain from entry hole.
7. Tilt the pump slightly to the left allowing remaining fuel to drain out and to get the fuel sender plastic level out from the tank.
8. Empty out any remaining fuel, and place on plastic (car mat or similar) out side of car for easy access.
9. Make a note of the 3 wires connection points, to ensure you put them back in the right place. (We stayed old fashioned, and used the shortest cable must go first method like a true professional)
10. Use a flat bladed screw driver and prize out the small plugs
11. Slide the plastic connector downwards and off the side of the fuel pump.
12. Cable up the new sender using the cable positioning you made a note of earlier.
13. Slide the plastic sender back onto the side of the pump
15. Place the rubber seal back around the fuel tank hole (carefully otherwise you will be arm deep in petrol hunting for it)
16. Carefully feed the fuel pump back into the tank, making sure the blue ‘lug’ is pointing to the back of the car.
17. Place the metal ring back on, and tap back round until tight.
18. Push the blue and black pipes back into place.
19. Reconnect the push block connectors on the top of the rubber covers
20. Place rubber cover back onto of the fuel pump
21. Cross fingers and attempt to start the car
22. If you’re still reading this, all is still well and your car is still in one piece.

Display other stats on digital climate control unit.
Most Audi’s fitted with the digital climate control are capable of exploiting it to display other information. It’s quite easy to do:
Press and hold the recirculation button. Then press the manual flow control up arrow. You should see a 1c. Press the temperature up (“+”) or down (“-“) buttons to select a code number. Then press the recirculation button again. The value should display. Press the temperature up or down button again to display another code.
NOTE: Air Flow Motor (V 71) and Potentiometer (G 113) are not installed in USA/Canada vehicles. Disregard values displayed for these components.
