Question about 2000 Volkswagen Jetta TDI

2000 VW Jetta High battery draw/dies 12-18 hours after charge

My 2000 VW Jetta GLS w/2.0 L engine battery keeps dieing due to a constant high draw on the battery when the car is shut off. When the battery cable is removed there is a considerable arc of electricity. There is a secondary cable which connects from the positive battery terminal to an elecrtric bus located on top of the battery cover (this bus has several wires which come off of it). I am able to narrow the high draw item on the car to the heavy gage red wire which comes off of the bus. What does this wire power? When I disconnect only this wire from the bus, the car will not turn over and the dash board LCDs go blank. Someone said the problem may be the voltage regulator. Any suggestions? Thank you.

Went through a puddle. Car died. Restarted a day


See these items:-

The starter must have been bad due to the water.

Bad PCM or ignition coil.

Corroded battery cables.

See timing belt.

Why does my paid off 2000 VW Jetta GLS make a high pitch buzzy grinding sound. Is it the alternator ,transmission,or timing Belts. What do I do and how mauch can it run me. Am I still covered with the


The trick is to take off the belt and spin the different things and see if any of them make the noise you hear.
Water pump, alternator, power steering, air pump, belt tensioner pulley. You could also briefly (30 seconds) run the engine without the belt and see if it still makes the noise.

For prices, you can check autozone.com or partsamerica.com

My 2009 hhr won't start. The first time the dealer said there was a wire that was loose wire to the fuse box, fixed wire. The second time the dealer said the battery was bad, replaced battery. The third...


sounds like a bad ground somewhere. that can burn out power wires due to a high amp draw and cause the battery not to charge. try hooking up the negitive cable directly to the engine to jumpstart it. if that works and the car dies as soon as you disconnect the cables a bad ground is very likely. and I have noticed the new gms are very weak in the charging/battery department. They are using very cheep batterys ,die very easy. also check fuses.

Check your vacuum lines, make sure there is no leaks, and go from there, then all you electrical connection in the engine compartment.
I have a 1996 Jetta Trek Edition, the hoses, and wire harness, are so brittle, any movement can cause hoses and wire insulation to crack.
