sounds like u need to put new fuel filter in, and be careful not to buy dirty fuel air cleaner might help as well
There is no problem...the problem was the alternator. You have fixed the problem.
If your 1997 Passat dies sometimes, you might have an issue with the alternator not charging the battery. You could also have a problem with the distributor or the coil.
Obviously check the battery. Anyway, if the alternator, battery, and wires connecting them are good the voltage regulator is next on the list.
A quick way to tell if there might be a problem with an alternator is to remove the positive side battery cable from the battery while the vehicle is idling. If the engine dies, odds are there is an alternator problem.
"Big" Battery Damage Alternator?No, it should not damage the alternator. If this has happened it's probable that the problem is somewhere in the wiring circuit connected to the battery and alternator.
Your alternator is probably rebuilt and not really new. I have had this problem several times and I have bought a new battery and alternator. The alternator keeps your battery charged and powers your electrical system, so even when driving you can lose all power in the car from the alternator draining your battery. Take the battery and alternator to an auto store and they will test both for free. Ask them about the difference in a rebuilt alternator and a brand new one. This is a very common problem.
Your distributor might need to be replaced. Answer #2: Check for loose or corroded cable connections at the battery posts; also, a loose belt could be the problem.
Possible alternator problem
Could be. But it might be an alternator problem instead of a batery problem. You need a good alternator to keep the bttery recharged. I wouldn't run out and buy a battery without getting the alternator checked.
have an alternator, battery, and electrical check to find out what the problem is. battery may not be taking a charge, or the alternator is not putting out enough voltage.
The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.
If the ignition isn't firing then you're looking at an electrical problem: Bad spark plugs, distributor, cables or battery. If you're frequently draining your battery and needing jump starts, the alternator could be failing as well.
