2001 vw passat check engine and emmission light on

I just bought a 2001 vw passat which had check engine and emission lights on. I took it to firestone service center. they said the third cylinder was misfiring and changed the starter plug. After I checked out from there the car starts to **** while driving. I took the car the next day and they suggested I have to change the cam position tensioner. I was about to take the car to another mechanic as the price they qouted was too high. Now the car doesnot start. I was thinking if I flush out the engine it might work. I want to know the right place to fix it as I dont trust the firestone service center anymore. I am from estes park area

    We just recently purchased a 2001 VW Passat for our daughter and the car had to be towed 2 days after we bought it (from a private party). They had given us the tags of the recent work done on the car which showed that the ingnition coil and all spark plugs and fuel filter were replaced. Also replaced was the timing chain (this past August) 2008, and the crank position sensor was replaced in November of 2008. IN January, before they sold it to us, the car had to be towed and the camshaft sensor was replaced at the same time they had it smogged. In Feb. of 2009 the car died on us and the mechanic said there was no spark to the engine, so he replaced the engine brain box with a salvaged part. One week later we had him reinstall the timing belt and reset by one tooth. The car ran OK, but started to sputter about a week later and this past Saturday (3/7/09) would not start at all. We had it towed to the VW dealership, and today (3/11/09) they tell me that the engine brain needs to be replaced. I called the mechanic who replaced that same part and he said it was not the "brain" but most likely the camshaft sensor (which was replaced in Jan. 09). We do not know who to believe. The dealership tells me that the engine is not getting any spark. Has anyone experienced a similar problem and can advise us what to do? We are at our wits end and cannot afford to replace this vehicle.

NO to the MAF Sensor Question, and Spark Plug Wires Or BOOT Will Cause Missfire. As For Mass Air Flow Sensor Easy Check is to Dissconnect it While Engine is Running And If ENGINE SMOOTHES OUT The Sensor is Bad

SOURCE: 2001 Beetle check engine light is on.

Hi, the MIL (engine check light) will only go out when the car has had 50 drive cycles - start, run to normal operating temperature and stop, without further faults. A normal EOBD code reader such as you used to check for the fault originally should also be able to cancel the fault and put the light out. If the code won't clear, suspect a faulty ignition coil. Which is a common fault on these vehicles.
Hope that helps Matt...

"Check engine light" EMISSIONS WORKSHOP! Do you want to shut it off??? After reading all of the negative comments and how much money Passat owners have spent due to this manufacturer's problem, I am going to save the day and save you $$$ by showing you how to "reset" the diagnostic computer which makes the "emissions workshop-check engine light come on! (This is the same thing the VW dealer will charge you hundreds of dollars to do.) To turn off the "Check Engine" (Emissions Workshop) light, simply follow these 5 basic steps:
1. Pop open the hood.
2. Insert the key in the ignition and turn without starting the engine until all of the dash indicators light and warning tones sound.
3. With the key still in the ignition, use a 10mm wrench or socket to loosen and completely disconnect the negative (-) battery cable from the battery. Wait about 60 seconds before reconnecting.
4. Re-connect and tighten the negative (-) cable to the battery and close the hood.
5. Start the engine. THE "CHECK ENGINE" LIGHT HAS GONE OUT!
If the light stays on, then there really is a problem. If it has turned off, be glad, but don't be surprised to see it come on again in a few weeks. If it comes on again, simply follow steps 1-5. Remember... This quick repair is for those who just can't stand looking at this light or afford to visit VW every time this light comes on. If you feel the need to service the vehicle, service the vehicle. I hope this has made your "NIGHTMARE" a little easier!!!

Sounds like it could be a mass airflow sensor failure. Take your car do your reputable mechanic and have them scan your computer to find out what the error code is, and then go from there. If it says that the mass airflow sensor is offline, I would look to make sure that the connector is properly secured on the air intake hose.

Cut them off is the simplest way but you must remember that you have o2 sensors that control your engines emissions and may affect the exhaust (emissions/smog tests) and by removing cats you check engine light may come on as a result so be cautious of this...

I own a 2001 VW Passat Wagon.3.0 liter, 6 cyl., 30 valve engine. The 'check engine' light and 'emissions workshop' messages came on and I need to know what the problem could be.


most autoparts stores will run the check engine light for you for free....I am assuming that you either have a clogged catalytic converter, or your o2 sensor is throwing a fault....have autozone check it out and post back.

Emmissions light has come on?


you need to get it scanned, i assume "emissions light" is your check engine light, or the "visit emissions workshop" message, which means, go to a shop and get it checked. The coolant disappearing means you probably have a leak. Another reason to check it,

Check engine emmission message


the emission system on any car sold n the USA is tested and certificated by the EPA to not pollute for 100,000 miles, these systems include the EGR (exhaust gas recirculation) system, the fuel vapor control system, the catalytic converters, the various sensors on the engine such as lambada sensors and engine temp sensors plus many others
