2005 TDI battery light

Today while driving on highway the battery light came on and then went off when I slowed down. The car has 71,000 mile on it. Any idea what it may be? Could it be the alternator, belt etc..

Check your battery terminals are not loose or corroded.
Check your alternator dive belt tension is OK.
If no problem with drive belt, it may be worn alternator brushes.
If the problem persists get the alternator checked.

Lights went out and radiator fan stays running after car is shut off


It sounds like an alternator, yet you say the fan still worked after you disconnected the battery? And the car was still running? Or the car died out. Sorry, need some more details on this one.

Don't know much about VW but if it's fine, and it doesn't happen again I wouldn't worry about it. If it does try resetting the ECU by removing the battery terminals and touching the positive lead(red wire) to the negative battery post. It might spark a little, this is just the capacitors discharging, resetting your ECU and starting over. It's like restarting your personal computer

Try to recharge your battery if its starts now ,the alternator must be bad,if still wont start make sure battery is good,then check the fuses and fuseable links.

Try resetting the CES by disconnecting the battery, waiting for 15-20 minutes, and reconnecting. Your ECM will have to relearn your driving style over the next 25 - 30 miles but should settle down after that. If the problem recurs, you may be due for a new battery.

2002 vw jetta tdi - problem with rpm gauge?


Hi, Did you notice the motor actually reving higher when the tachometer was reading a higher rpm.. If it was it could be your transmission slipping.. Set your cruise control and listen to your motor while the tachometer starts moving erratically.. Good Luck
