Almost positive the voltage regulator on a B5 Passat is built into the alternator, so you would have to replaced the whole alternator.
It could definitely also be the battery too. How old is the battery?

2005 Ford Freestar, altenator went out, During the process the Brake/ABS dash lights came on, when the battery got low, The transmission shifts fine, working normal.


ok you changed the altenator did you do this yourself ? now take off the battery cables and reconnect them to clear the trouble codes and use your key fob when the alarm sounds to stop it from going into theft mode put the key in the ignition and turn it to the run position do not try to start it yet wait about 3 minutes for the system to get all the voltage parameters back then turn the key off then start the car it may idle rough at first do not apply any gas peddle just let it run after the idle stabilizes drive the vehicle so it can continue to relearn the operating system parameters if the lights come on again take it to auto zone or advance ETC. to get it scanned but I think you should be ok the system works by voltage and being the altenator went bad the systems voltage was way down causing the codes good luck Stephen

Car won't start , said it was disabled for


THe key has a code in it that is read by the engine immobiliser. BY removing the key and reinserting you are giving the immobiliser a chance to read the code again. Give it a try. THe battery in your key may be getting low and needs replacing.

Volt meter does not show increase in voltage after engine is started


If you run your car for a few days and the battery starts dieing also, the voltage regulator in the alternator is probably shot which means you'll probably have to replace the whole alternator.

have the alternator bench tested for faulty rectifier diode pack
it may be charging the correct voltage but it is AC voltage and not DC voltage
in which case the battery will die quickly
next to check is the voltage regulator
it has to be 4.5-14.8 volts DC and if it in the ECM unit , will require a new ECM to fix

your altenator has a built in voltage regulator in the back of it. suggest you replace the altenator to make the problem go away.the car will do all kinds of crazy stuff if it's not getting 12volts all the time, it won;;t get 12volts all the time because the regulator isn't operarating properly.you're running off the charge in battery most of the time because the regulators kicking in @ out after it heats up. hope this helps!!

The first question for you is, What is the charging output for the altenator at idle?? If less than 12.3 volts, replace altenator. Typically, the altenator gets tested at 2500-3000 rpm on a bench tester. Your problem may be in the low rpm output range.

Alternator not charging on a 1998 cadillac deville after i replaced it with a new one and still the same problem, it will start charging if i bring the rpm's up


Before you start changing everything Test. Check voltage at battery with key off it should read 11.7 to 11.9. Now start car voltage should be 13.5 roughly, rev engine to 2000rpm and voltage should climb another 1.5 average. Let off rpms and it should drop back to intial reading of around 13.5. If things don,t test right then its cables or altenator or ground from battery to altenator housing.

Al, this truck has a regulator locted inside the altenator, it also has a relay located in the power distribution box under the hood, see your owners manual for exact location, to verify an no charging problem, start the truck and measure the voltage at the battery, it should read 13.5v-14.5v, if not then the altenator is not working, most common problem is regulator failure requiring altenator replacement, hope this helps, let me know

Voltage regulator


Voltage regulator is built-in to the alternator assembly.

Have you tried replacing the battery?
A battery with a shorted cell will not charge properly and may even damage an alternator or regulator.

Note1: use a digital voltmeter (about $25 at Lowe's or Radio Shack) and check voltage across batt terminals while engine running. If more than 12.6 Volts DC and more typically about 13 Volts, then the alternator is working.

Note2: from Jan 98 to May 98 shows a different part # alternator than June - Dec 98
check the manufacture date on your driver door edge.
