Top 20 2003 Audi A6 Questions & Answers

Question edited for clarity. Question moved to model category. If the thermostat housing broke, did it spray the fuse box, all the wiring and the ECM with boiling water whilst the engine was running and electrically energised? Crank no start always has ideas for fixing https://www.google.com/search?q=2003+audi+a6+quattro+2.7+biturbo%2C+no+crank+no+start But not when you throw the boiling water scenario into the equation. You need a good local auto electrician with a 5 grand scan tool computer and the ability to understand wiring and wet electrics. https://www.google.com/search?q=mobile+auto+electrician+near+me ..

Not sure if there are carbs on car or if it is direct injection. If carbs spray into float chamber(s) if injction I think you will have to spray into cylinders via holes for spark plugs.

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 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.
