Passat (B5) :: CEL Accompanied By Emissions Workshop Message Came On
Jul 7, 2008
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.

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...

Car is a 2000 Passat Wagon 1.8T ATW FWD
I get the P1128 code and Emissions Workshop warning most of the year, then it cycles off in the summer. It went off yesterday, back on today, and I imagine it will go off again for weeks/months as the weather heats up.
Things I've tried so far:
Replaced MAF sensor
Replaced MAF wiring harness
Replaced front 02 sensor
Replaced air filter
Replaced cracked vacuum tubes, at least those accessible from the top. Some of the hidden lengths theoretically could be at issue but a mechanic said they were ok.
What I've not replaced is the secondary air pump. (Mechanic told me it's dry and checks okay.)

I own a 2000 V6 Passat with 68K miles. For the last 3 months, I have had check engine & emissions workshop lights. During the last month, the car will not start at random times (although never first thing in the morning, only after it has been recently driven); this will happen 1 or 2 times a day. After waiting 1-2 minutes, the car will usually start on the 2nd try; it has always started by the 3rd try. Once started, the car runs fine, although there is initially a strong gas smell. I took the car to a local mechanic, who changed the air mass meter, which had no effect. The mechanic now wants to change the O2 sensors. Unfortunately, I do not know the codes. By the way, the car had an emissions workshop light in 12/04: the light went off when the dealer did work under a "WE recall", which I believe means that it replaced the secondary air vacuum line.

On Sunday the high-pitched beep went off while driving, followed by the orange engine light to the left of the speedo needle and EMISSIONS WORKSHOP coming up on the computer.
Everything is normal. Revs are fine, temp is fine, no other lights come on. I checked the coolant and that is fine too. This happened about two months ago, but it stopped after a couple of days.
Could this be something like an O2 censor?

I have a 2000 Passat 1.8T. When I start it up in the morning I hear a loud obnoxious noise like a vacuum leak from the engine compartment. It lasts for about 1.5 minutes then runs normally. After about a minute it starts up again and only last for about 7 seconds...ish. When I drive it afterwards, less that a half block or so, the CEL light goes on after 1 beep. Also, at that time I get a messages from the instrument panel that says "Emissions Workshop 1". I've read that it could be a simple damaged vacuum hose to the secondary air pump. Definitely a huge price difference to repair.
This morning is was colder outside than usual and the dash kept beeping and flashing the "Emissions Workshop 1" code intermittently.

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.

I Encountered a problem today on my way back from shopping. I started the car as usual and noticed i was down on power and heard a weird noise from the exhaust in the back part of the car. I pulled over restarted and a message popped up saying Emissions Garage and a yellow engine control light stayed on. Got home popped the hood and i heard this turbo sound like in the imports. I am pretty sure its the air going back in to the turbo as if in the blow off valve wasn't doing its job. Also a weird noise on all the air intake pipe specially at the air filter.

On New Years day the water pump on my Golf MK4 broke and all coolant leaked out. I had that replaced together with the cam belt. When I got the car back, the next day when the car was starting from cold I noticed it was very rough when idle, car about to stall then RPM jumps, drops and jumps up again. I drove for a minute and when stopped at some lights, the car juddered and "Emissions Workshop" warning came up along with 'ECU / engine warning light' and 'Brake system / brake fluid warning light'. Drove a couple more minutes and all warnings disappeared. Was fine for rest of the day.
Same thing happened the next morning. Once warmed up it is fine for the rest of the day unless the car is left undriven long enough for it to be completely cold. I know nothing about cars so have relied on my local garage. I was told the diagnostics reported a fault with the coil pack so had that changed along with plugs and leads. The next morning the same problem was still there. Then told could be coolant temperature sensor so had that replaced too. Still same problem.

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.

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.

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.

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

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?
