My 2000 vw will not trun over or come out of park

You need the VW scanner to reset the system and reprogram it after loss of power to the system. Aren't VW's great?

This sounds like the anti theft system is active, you jump start it but it dies out after a few seconds , if this is correct then try another key. the other thing can be a weak battery make sure the battery is fully charged and good,

Do you check the battery??? If the battery is fine, it seems you have a bad alternator.

nop but u should check the alarm. some cars when the battery its changed activate an silent alarm and doesnt let the car run

renew the locks .

Maybe your key remote batteries need to be changed. Also have it scanned for DTC's which I believe you may have quite a few stored in memory, problems you weren't aware of.

It's possible that the wire that connects the starter to the battery has corrosion/battery acid on it and is creating a lot of resistance in the wire. Sometimes you'll have a good connection, sometimes you'll have a bad connection thus creating an intermittent problem. You should check the wire that hooks into the starter, disconnect it, clean it with a small, wire bristle brush, and maybe spray some of that red, battery terminal spray on it, then hook it back up. Make sure you disconnect the battery first. It's pretty hard to get down in there but you can save yourself a ton of money if you do it yourself. You may be able to reach it better from underneath if you drive the car up on some ramps.

Take to dealer. Vehicle needs vag-com to be reprogrammed. Bring all keys with you to dealer.

when you try starting the car look at the gauge cluster, you will most likely see a small emblem light up that has a picture of a key in it. that is the immobilizer light and the problem is it doesn't recognize the key as it's own so it won't start thinking it is being stolen. try all the keys you have if none of them will work and all set that light off it will have to be towed into your local dealer to have it all recoded.

It's an ignition problem. If you keep trying to turn over it will start. It's an anti theft device they installed. The little car with the flashing key. Someone likely tampered with your ignition before for this to happen.
