The German manufacturers came up with a great new idea that many others have now copied and that is to eliminate the under bonnet filler tube and dip stick. Some of the German manufacturers have decided to eliminate engine oil dip sticks as well. These people are just so innovative.

Thus you have to use the correct filling procedure as laid down by the manufacturer which involves filling the auto transmission from under the vehicle by removing the filler plug on the side of the auto unit and pumping in the fluid. It used to be so much easier.
Obviously this is best done on a lift/hoist and the vehicle must be level.

Here is some info on the Audi A6 auto trans you may find of use..................

I have an A4 and did this to re-program my key:

1. used the key to start the car...then turned it off
2. put the key in the driver door (door closed)
3. pressed the lock button on the key fob once
4. turned the key to lock the door.

This is basically the steps in the owners manual, but the car must be started with the key first, and the key must be in the door lock before pressing the lock button.

You would be better off to pay $16.00 for a haynes repair manual for that car, it gives a step by step procedure, It would take a lot to tell you on here. If you are going to change the strut springs to the new ones, you need a spring compressor, and if you don't know what your doing and be very careful, and the spring slips and hits you, you will be severelly injured.

I would check the thermostat first. Remove the thermostat and place it in a pan of water on the stove. Place a thermometer in the water with the thermostat and slowly increase the temperature until you have reached 194 degrees Fahrenheit or 90 degrees Celsius. Watch closely for the thermostat to open slightly. If it opens then the thermostat is good. If it does not open, replace it. Try that first and see what you come up with.

Read your owners manual?

Check for Codes? (the same day you got any dash lights on)
