Can I get an explanation of the components involved in the EPC system/circut. Car gets wet and epc light comes on with emissions workshop. I don't want to get rid of my Volkswagen Passat 2000.
View 2 RepliesI 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.
View 7 RepliesMy 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...
View 9 RepliesI 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.
When I started my car the check engine light came on and it emissions workshop message came up. What is this? My car seems to be running fine.

View 5 RepliesI'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 have a 2004 B5 130BHP and the display occasionally reads Emissions Workshop.

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.)
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?
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.
I got a Passat 2000 OBD-II scanner won't read for emissions testing. I did the test in 5 different place all the time when they ask to turn the key and the computer from emission test give a error and stop.
I have a radio aftermarket one of my friend have this problem and he have to install the original radio. So I buy the wire harness and the radio i install and still not able to do the emissions test.
My ABS light is flashing but my friend said this is not a problem he fix more than 4 car just replacing the aftermarket radio....
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.
So im new to this form and i have many questions about my car. I have a 2000 Passat 1.8 20v Turbo and my emissions light keeps coming on as soon as i start the car and start driving. there are two codes that came up when my buddy scanned it. ones P1128 and the other is P0411 Sec. Air Injection Incorrct flow. Also my sunroof only opens up it doesnt slid back can this be fixed?
View 2 RepliesI 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.
View 4 RepliesA little embarrassed about a problem I have had getting the Emissions computer to reset for emissions testing in Maryland. I tried everything the testing station suggested, but could not get the codes to reset, for readiness for emissions testing. I surrendered after 5 or 6 trips to the testing station, and took it to my very trusted mechanic, thinking I had a bad ECU, and he would need to replace it. I would have done it myself, but figured I would not be able to re-program it myself, so would rely on my mechanic.
Got the car back, fixed for less than $50 (they did other maintenance work as well). Guess what it was? It was a blown fuse! This is the second time this 2000 Explorer XLT, 5.0 has me stumped and it was just a fuse - first time was tow-hitch lighting. So now, no matter what, I will check all the fuses first! Regardless of the problem - ok, maybe only a last resort when I have a flat tire
2000 Ford Explorer XLT, 5.0L ......
What are the values of CO2 emissions from the 2.0T automatic ? i think it should be in g/mi. the only info i found is that the engine complies with Bin 8 EPA..
View 7 RepliesI am getting a code for my 2003 Accent (65,000 miles). The code is P1401 and it is telling me the fix is replace Evaporative Emissions Canister. I asked my mechanic about 2 months ago about this and he wasn't too concerned.
We are not in an area where they do Emission testing. I will be driving back home to WI . and want to know if I should be concerned. The round trip is about 900 miles.
This began as a troubleshooting exercise for a P0442 code (2002 model) indicating a leak in the evap emissions system. Often caused by simple things like a loose/poorly sealing filler cap. Not this time
It's a neat design, tucked away up in the fender well. Even sports a very effective stone guard (plastic shield) which hides all that tubing from view. But the shield also traps all the road salt and mud and packs it into the crevices between the tubes where it stays from one winter till the next. Even a powerful car wash probably can't dislodge the caked on mess once solidified.
The EPC light came on the the MFD read: Engine Fault Workshop! This happened once before for about a second, but today the car dropped to limp mode and would not recover. She had a flat bed take it to the dealer and they "reset the throttle" and it is okay now. Aside from running the adaption routine, I am clueless what this means. I will scan the codes tonight.
