2002 VW Jetta won't start

You may have blow the fuses check all of them.

You need to charge your battery up more. Either get a battery charger or leave the jumper cables hooked up for a longer period of time.
Your battery was probably completely dead. You might even need a new battery...they really don't like to be completely drained.

try unplugging the battery and replugging it and then starting the car. hope that helps

yes its a fairly common fault with all VW motors from this age including skoda and seat

2002 volkswagon jetta has a security issue since the battery ran low. It will start but not continoue to run. I have a flashing indicator of a car /key on the panel board

it can be any number of things, diagnostic equipment is required to find fault code

The battery needs to be charged or you need to jump start the vehicle.

Check the battery out put to see if it is at least 12.25 volts(may need to have it load checked).If the battery checks good,remove battery cables and clean them real shiney,also the battery terminals,and replace them back on the battery,WARNING,DO NOT DISCONNET THE BATTERY WITHOUT PLUGING A 12 VOLT POWER SOURSE INTO THE CIGARET LIGHTER PLUG,OR EQUAL.If you do not plug in a power sourse to the car,the computer will loose all it`s memory,and will have to go to the dealer to be reflashed.

You need to start with checking the fuses, sounds like they are blown. Fuse panel is on side of drivers dash, you need to remove panel, just pulls off.

the relay is going bad. its freezing up. this will sometimes happen when it gets stuck in the on position.
