Passat (B5) :: Alternator Workshop Message And Battery Light Came On
May 22, 2012
I have a B5 Passat that came in with the alternator workshop light on. Upon a few tests i determined the alternator was bad. I removed the alternator and installed a remand one that was correct for the vehicle. amps and all. After getting it all back together i started it and the car ran fine. I drove it around and shut the car off. Customer took the vehicle and after 15 minutes the car was back for the alternator workshop message being on and battery light again.
I restarted the car and it was off. I restarted it again and it came back on. Replaced the Alternator again with another and took it for a more extensive drive. The lights stayed off this time. I parked the vehicle and shut it down. Waited a few moments and restarted it just to be safe, the lights had came back on again..... After testing it more I've come to find that when the lights are off the alternator is charging the vehicle as it should and when there on the vehicle is not charging. I don't know what it could be at this point but I am absolutely sure its not the alternator.... I honestly don't think this many are bad in a row.

Since it rained here in Socal today...i got the dreaded "Alternator Workshop" message on my console...It showed up for a split sec just enough time for me to read it. I had just finish installing my Evoms Vflow intake so I started my car and rev'd a few times before the message showed up. It quickly disappeared right after it showed up. I've been reading that the belt could be wet from the rain causing this message or definitely my alternator is bad.
What should I be checking to make sure everything is ok? My car only has 41k miles and it has been sitting for almost 2 weeks.

Don't know know the cause of this message. From what I've been able to find, it sounds like a serpentine belt.

So i JUST got my timing belt replaced on my 2001 B5 Passat 4motion, took it in and got it done. Now when the tech was working on it he said that the car was slow cranking one day, and I have intermittantly seen the same thing before, but i have known for a while that I need a new battery, its old, and randomly have little power, but it has always worked once the car is started.
As soon as i picked the car up yesterday I got the "alternator workshop warning" and quickly the car started to act funny as systems lost enough power to not function correctly (abs light, brake light, etc). Now is there ANYTHING else this could be beside the alternator? fuses, wires, other faults, etc, etc.

I'm the orgional owner of a 2001 Passat 1.8T with manual transmission...It has 93,000 miles on it.
Last week, the check engine light came on and a "Emissions Workshop!" message light came on. It was on for a few days,then disappeared for a few days,only to come back.
I took it to Autozone for a reading. Here's the results:
"The PCM has determined that during testing,the fuel system for bank 1 was too lean.
Definition: Fuel trim bank one condition
Explanation: The powertrain control module uses the oxygen sensor to calculate the air/fuel ratio of the engine.
The computer has recognized a rich or lean condition on one engine bank only.
Probable Causes:1. If bank one and two codes set together fuel pressure or MAF Sensor
2. Oxygen sensor defective
3. Ignition misfire-repair
4. Fuel injector repair.
Someone here asked if my oil was recently changed-It was.
Driveability hasn't been affected,nor has mpg. The car drives as normal.
I need to go on a 1,000 mile trip in a few days,and don't think I'll have time to have the car serviced.

I bought a 2000 Passat GLS w/ the V6 a couple weeks ago, and the very next day after buying it, the CEL came on and something popped on saying Emissions Workshop. I waited a couple weeks to see if it would turn off, but it didn't so I took it to a mechanic.
The first time, they just said a couple codes were off so they reset the computer. About 20 miles later, the lights came back on. I took it back and they hooked it up to their computer again.
They said the o2 sensors were perfect, and it was most likely some sort of resistance in one of my cats. The car runs absolutely perfect. I just wanted to get some feedback from ya'll because I do not want to pay the money to have a cat replaced if I don't have to.

I've got the the alternator workshop on my screen and the battery light, again. I've replaced the battery (it was bad) and it drove fine for about 15 min then it came back again. Now it comes back under load (accelerating, revving). The car starts fine now but after a lil but of driving, the car idles high (1k rpm) instead of the 500-700 rpm. I turn the car off and it will go back to the normal idle. I've obviously read about a poss bad alternator but I've read about loose alternator belts. Fixing this issue with tightening the belt or has everyone just replaced the alternator?

My battery went dead so I replaced with new. This did not fix the problem so I replaced the alternator. It's working now but the battery light stays on. I think I still have a problem.

2002 Ford Focus SE with 130k miles on it. For the past 4 months the battery light flashes randomly while driving. The flashing and frequency of flashing doesn't seem related to anything I can tell including temperature, length of time the car is running, speed or any variable. Seems like it should be an alternator, but that was replaced less than an year ago and it also has a new battery. The alternator always checks out fine at the mechanic and it will never flash for the mechanic. It went 1 month with no flashing and suddenly it will now flash maybe 20 times in a 5 mile drive. Yesterday it just died at a stoplight with no warning, but then after shutting everything off it started just fine and the battery light didn't turn on for the 2 miles to home.

A few weeks ago my alternator workshop and battery light came on while i was driving. I made it home and the next day my battery was dead so logically figured my alternator went. I replaced the alternator and the lights went out, but as I drive it will flash on and off real quick and sometimes it comes on at higher rpms and sometimes it doesn't even come on. I've been looking around for an answer but I cant seem to find one. I've read that it could be the belt or the tensioner.

Alright way to kick off the new year. I drove my car to and from work today... no issues. I get ready to leave to hang out with friends, turn the car on, and the message "Exhaust Workshop!" comes up. It then goes away, but the CEL stays on.

My emissions workshop light is staying on now in my passat. I don't have a Vag-Com cable for my laptop yet so I scanned for codes with the generic code scanner at Advance Auto. It came up with something about the downstream 02's low voltage or something close to that. It has just over 100k on it now... is this a common issue with these cars? Is it usually the o2's that are the culprit or is it usually a Cat problem? I replaced the PCV hoses (those crappy wire loom looking pieces that fall apart under the engine covers) with much nicer fuel hose and barb fittings thinking that they might have been the culprit, but that was before I scanned it, it obviously didn't work. 2000 LX 4-Motion...

When I was in the touareg a few minutes before everything was fine. Then I unlocked it got in and inserted key and the steering will not unlock, ignition will not turn on, or starter crank. The battery voltage is fine all accessories work. I tried to disconnect the ground strap and reconnected, no change. When I closed the door I saw the red message come on stating "Steering Defective Workshop". The message doesn't always reappear.

I have been getting the "Running Gear Fault Workshop!" message on my MFI almost every day for about a week now. To clear it, all I have to do is shut down and restart and it goes away for pretty much the rest of the day. Is this something that I should get into the shop ASAP? Or can it wait a month until my scheduled 20,000 mile service?

Came back from car wash (probably no significance) pulled in garage turned off ignition and the title message came up in the center display. Car will not start. At this point I have no Vag Com and the car will not start.

I posted last week that I was getting an intermittent "Steering Failure - Workshop" message on my '04 V-8 Phaeton. I asked forum members if I was alone and no one responded to the post. Last week I made an appointment with my VW dealer to get the car's steering fault looked at but I wasn't fast enough. The other day the car would not let me start it. The 'steering failure workshop' problem doesn't seem to be a mechanical issue. There are two other '04 Phaeton's at my dealer right now with the same problem. It looks like my car will join the party awaiting new steering control modules. The back-order on the modules appears to be at least another three weeks. Funny, you can get an entire Phaeton steering column in two days. If and when this steering module goes south all kinds of fun interior electrical glitches jump on board. No one ever said owning a Phaeton wouldn't be interesting and yes I still plan on keeping it for a very long time.

I've been getting this "system fault workshop!" error message popping up like crazy. Its got a picture of a key, and makes the audible beep when it appears. on a short drive to work, maybe 10 minutes, it will randomly come on and beep anywhere from 3-10 times during my drive. The car starts and drives perfectly fine. This has been happening for a little over a week now. I noticed one post about this before, but that owner seemed to have different symptoms as their car wouldn't start. I really would hate to bring it into the dealership, as I've just paid them a small fortune fixing different things to finally get down to the bottom of it to find out i needed new fuel pump modules.

My 2004 Phaeton with a little over 100k miles on it has been giving me a problem with the air ride suspension. When starting the vehicle, a "Level Fault - Workshop" message is displayed on the instrument cluster, and the car has been slowly sinking as the air ride (I presume) slowly deflates. Around 10,000 miles ago, I had a problem with the suspension, but that time the car immediately and actively sank; this was solved by replacing the air ride computer (it is the B, not C-type). I've tried replacing the computer with another B-type computer, but to no avail. The local VW dealer and an independent import car garage have told me some things, and I would like to learn more about this problem and possible ways to try and solve it.
1. I have been told that no voltage is making it from the computer to the left front sensor. Dealer says its the computer, but could this possibly be the wiring harness or a bad connection? If so, how do I get into the wheel well in order to test this hypothesis? My best guess is it isn't the computer, as the car never actively sank (this happened when the original computer went bad).
2. I have also been told that the right rear sensor is bad. Is this a part I can replace with a modest amount of auto knowledge? I do my own oil, replace brake pads/rotors, etc. If so, any drawing/maintenance manual parts list available?
3. I have heard conflicting reports as to a freshly-ordered sensor being and not being compatible with the B-type computer. Dealer told me new sensors will only speak to a C-computer; independent garage told me new sensors will speak to my B computer. Who is correct?
From a few hours of internet browsing from the first instance and this second instance of failure, it seems this is a somewhat common issue with the 2004 Phaeton.
