Passat (B5) :: Code P1128 Along With Emissions Workshop Warning Appeared
Apr 22, 2013
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 have a 2004 B5 130BHP and the display occasionally reads Emissions Workshop.

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.

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.

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'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...

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.

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.

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

I actually just bought a used 2004 Prius with 207,011 miles on it from out of state. I had a car shipped to me by a flatbed trailer. I just got the car the last weekend. However, It has a yellow engine light and a big red triangle with an exclamation mark (!) on a dashboard, and a red car with ! on top left of a display screen.
I drove it to a DMV to get it registered and took it to Pep Boys near my place since I have to get it an emission inspection within 10 days of registration anyways.
They ran a diagnostic test and found 2 current error codes (C2310-open/short in battery circuit & C2318-low voltage error) and 1 history code (P0A80-hybrid battery pack needs replaced), so they didn’t perform the inspection; otherwise, it would have a failed record). They told me that the car has had problems before and the problems are about a hybrid transaxle and a hybrid battery pack. They also told me that I need to visit a Toyota dealer to get them fixed in order to pass the inspection, and they warned me that is going to cost me a large four digit probably . So, they suggested me to just trade it in because it is not worth repairing. They also told me that a dealer who sold me the car probably would have done something to the car, that’s why it didn’t illuminate any warning lights before.
I tried to gather as much information as I could, so I asked the shipper if he noticed any warning lights but he didn’t think so; one thing he noticed was the hybrid battery isn’t charged because the engine started every time he moved the car.
I plan to take a car to another auto shop near my place as well in order to have them double check the issues and give me a repair estimate before taking a long trip to Toyota dealer.

Bunch of warning lights appeared and the dealer said it's code P0a80 and they recommend replacing the battery. I'd like to try to fix this myself and would like to hear your thoughts...
Plan is to check the traction battery for corrosion and use a voltmeter to test the cells and replace if needed. Prius 2004, 158,000.

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.

Our 2.0T (2008 Passat Komfort Wagon) with 70K miles is sitting in a mall parking lot and won't turn over. The lights and accessories all function just fine, and don't change/benefit from a battery jump. DRLs and all dash indicators light up like normal.
We push in the key fob and absolutely nothing happens. No error messages or anything. I tried a half dozen times; no change. Two things to know:
1) The car is under a recall for defective Electronic Steering Column Lock. I understand this can invoke the immobilizer? Car does seem immobilized. (I hadn't gotten the car in for the recall.)
2) The car recently ran rough and threw an Emissions system code. I hadn't gotten that code read, yet, but the roughness sorted itself out. I think this is unrelated and may be a case of "car wash syndrome" as my wife and son occasionally run the car for a minute or less to move it from the driveway to the street.

P1128. Have had the code over and over!! No vacuum leaks and I've been through 2 MAFs. I've cleaned the throttle body, changed intake manifold gasket, changed plugs and wires, and put a new air filter in.
The code comes back every few months or so and the car becomes undriveable. Last changed my MAF back in December and the code is back already. What am I missing?

I have a 2000 accent 1.5L I was having issues with the maf. I was running a cold air intake but started having issues. I removed the intake and replaced with stock config. I cleaned the maf and re-installed. The car will run fine, build rpm and return to idle with no problems. The second I put it in gear and try to move the engine will misfire and rattle itself until it quits. I have been driving around for approx a week with the maf disconnected seeing as it seems to run alright, just lacks a bit of power it seems.
