Passat (B5) :: Code P1128 Along With Emissions Workshop Warning Appeared
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.)
Passat (B5) :: High-pitched Beep Went Off While Driving - Emissions Workshop Warning
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?
Golf IV / Jetta IV :: Car Juddered And Emissions Workshop Warning Came Up
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.

View 5 RepliesPassat (B5) :: CEL Accompanied By Emissions Workshop Message Came On
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.
Passat (B5) :: 2000 - EPC Light Came On With Emissions Workshop?

View 2 RepliesPassat (B5) :: CEL Came On And Emissions Workshop Message Popped Up
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.
Passat (B5) :: Emissions Workshop Light Staying 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...

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.

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.
Passat (B6) :: 2007 1.9t Lost Almost All Power And Alert Emissions Garage Came On Display
About some four months ago, was driving home from work and the car lost almost all the power and an alert "emissions garage" came on on the display. I had it looked at the VW dealership in Malta and they told me that the turbo diaphragm got jammed and they managed to get it working agin without changing it. After 4 weeks the same....
Took it this time to my mechanic, who works only on VW's and he immediately blamed the diaphragm again so after checking it he changed the diaphragm with a second hand one and also the emissions control box. After driving it for two months .....the same problem once again....

Passat (B5) :: 2001 - Got Alternator Workshop Warning - Electrical Systems Lost Power
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.
Passat (B5) :: Display Warning Check Gas Cap
Started the car on Saturday and drove about 2 miles. Chime came on and display read something like "check gas cap" or "tighten gas cap". Went off about 10 seconds later and never came on again. Cap was tight. Might weather have something to do with this? Beastly hot that day (98) and tank was half full. Never saw that display before.
View 1 RepliesPhaeton :: Level Workshop Warning Appeared
My '04 with 47K on the clock just announced 'Level Workshop'. The warning does not come on right away and takes several minutes to re appear after the car has been turned off and restarted. The car is level, the ride height adjustment functions perfectly, the damping selection functions as before and the jacking control is working the way it is supposed 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?

It's Sunday afternoon and -20 degrees in northern Wisconsin. We are at the cabin after a nice weekend in the snow. I start the treg and the MFI has a yellow differential symbol. Displaying Status, the MFI says "System Fault" and "Workshop!" That doesn't sound good so I call 24 Hr assistance and they can send a tow truck 90 miles but that can't tell me what the warning means. Naturally, the Owner's lit says nothing about this warning.

For the first time in 3 years the emissions light (yellow engine icon) is on. Have 88k miles so guess I'll have it checked out at 90,000. Is it ok to run it that long?
