The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.

Put the battery onto a battery charger. It sounds like the cold cranking amps capacity of your battery is low. Starting a car that is cold and sat, is ******* the battery. The next cranking is easier and the oil has been moved and things are now lubricated. That car should be on its third battery for a 2003, and I bet it is the second. You are looking at a new battery every 5 to 7 years depending on make and how it was looked after.

You can also make sure that the battery terminals and clamps are clean and not oxidised. Make sure you keep power to the system, with using a battery charger or use a length of wire wrapped around the battery terminal and the battery lead, otherwise you will have to re-pair the chips in the antitheft system.

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. Pleae note have never used starter fluid on direc t injection my self so I am really not sure if that will work. I assume that you have checked that fuel is getting to engine. Hope this helps.

The smell is probably related to the catalic converter when a cat goes bad it creates a smell similar to rotten eggs. You might need to replace the catalic converter. This will improve gas mileage and performance. The hot air blowing from the AC is probably a low charge on the Freon.

Is it a manual transmission or an automatic? If it's a manual (clutch pedal), then you've got a problem for the shop. If an automatic, it should shift into a forward gear or reverse whenever you depress the brake.

Where is the TCM on 2003 Audi A4 1 8t located

IN ANOTHER post I read
Remove the RH seat, rear seat bottom, and plastic trim holding the right side carpet down, unbolt the seatbelt from the floor, and the carpet will pull up easily. Transmission computer is in a plastic box under the carpet there.
