My 2000 Volkswagen Beetle takes a jump then the next day won't...

possible that the mechanic who sis not auto electrical qualified has damaged the alternator when fitting it of has fitted the wrong unit ( internal voltage regulation as opposed to external voltage regulation) take it to an accredited auto electrician for a bench test , have the voltage regulator tested and load test the battery as well
batteries can be defective for manufacture

check battery volts should be 12.6 volts.if not battery dead.have battery charged and test if battery can be charged alternator faulty.if battery dead cant be charged replace battery.and clean battery cables if EPC warning light still flash have vechicle code scan for faulty accelerator control system or mass air flow sensor.to get vechicle started after replacing battery just turn ignition switch to the on position for 30 seconds then turn off ignition switch then start engine.

I also have a problem with my 2001 beetle my brakes jam on as soon as you touch the brake pedel and the only way to release then is to release the nipple on the caliper can any help its driving me mad

Hi, seems to me it's time for a new battery, probably the original battery in the car and 72 -78 months is a good useful life, however you can pull in to a place like auto zone ( I suggest at a time when they are not that busy, early a.m. ) and they will do a diagnostic check for free and check out the charging system , battery , and any drainage of current when everything is off for you but I'm sure it will be ok or it would not crank all day but the long over nite hours drains what little voltage that is in the battery. A battery that is bad will not fully charge because of a bad cell inside of it. Good luck, hope a battery fixes you up!!

your charging mechanism may ave gone bad or even your alternator. you can check those things out at autozone. they'll check it and i think it's free

You need to get your injectors checked.

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

i think you should take the car to a local parts house and have them to test the charging system . If the voltage regulator has stuck it could be pulling a constant draw on your battery also check at night to make sure that none of your lights are on sometimes the light switches can go bad and cause this to happen such as hood or trunk.Hope this has helped you out some!!

Hi

Sounds like your battery, have you had it heavy discharge tested ?

Get the alternator charging rate tested if battery tests OK.

Good Luck !

Please give a FixYa rating !

OK, it sounds like the battery is dead flat, or just dead. First thing to check is the voltage on the battery - if it is 12 to 13v it might just need recharging, but if it is a lot less it could be due for replacement.
You should be able to get it running by getting it jump started using cables from another car. When you get the engine running again check that no interior lights stay on after you close the door, and that no audio systems or other electrical items have been left on.

If the battery is more than three years old, it is probably just worn out, but if it is a lot newer, come back with more info and I will try to help you further.

I take it you have a "real" key to get you inside so you can open the hood / bonnet?

Hope this helps a bit to start with. D.
