Disconnect battery now won t start

SOURCE: Car won't start.

Hello again, You could now have a driver authorization problem.
1. Plug your central locking pump back in.
2. Make sure that your remote batteries are good.
3. Lock and unlock the car with the remote.
4. Try to start car.
5. If no start you may have to synchronize the anti-theft system.
6. Point remote at the interior rear view mirror, press button on remote twice and turn ignition key key on within 30 seconds.
7. Turn key off and then back on and try to start car.
If car starts, you will need to find out why the pump won't shut off.
You may be able to unplug the pump after you are able to start the car but this I am not sure of.
CYA, Gator241

check the fuses in the POWER DISTRIBUTION BOX under the hood, There is a 75A in-line fuse and #11 - 15A fuse see if they are good.... test your alt. loom for opens, and cables .....hope this helps...GL

SOURCE: electric windows and central locking wont work

First check the battery voltage when the windows and door locks will not work (before driving) Will they function if you connect a battery charger? (Low battery voltage) This condition may be related to the security system (if installed) or poor electrical connection to the battery bus that is overcome when the alternator is charging.Be sure to check for 12V connection to the ECM and security Module (if installed)
You will probally need a schematic to check the wireing, Start with the 12v to the windows switches and discover where the power is missing. It will probally be common to the lock problem at some point.
Good Luck

sorry to say, you will need to take it in, it needs to be hooked up to their computer to reset and have it start up poperly. It just like a pc when it crash it will try to start in safe mode until you select "Normal" start up

SOURCE: my 2001 audi seems to start up fine and but after

have your alternator tested it sounds like your battery is pushing out out the power to your engine which causes the battery to drain. if you can start the car again pull the negative battery cable if the car dies after you remove the cable then your alternator is shot.
