Emission workshop warning

I think you should replace the ECM after flooding thats where it all begins.

may have cracked vacuum lines.

Its probably your computer. Had the same thing happen to me about ten years back. About 500 dollars. better off finding one on ebay or at a junk yard.

Battery was diconnected for 1 minute and then reconnected. All lights are off.

You need the OBD codes checked to be certain of the problem. If engine is running ok with the light on, it may well be an oxygen sensor problem.

"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!!!

it sound like its mis-fireing new spark plugs

PCV hose. I had the same problem...Hear air escaping from mine..I just put some hose tape over mine, and when I got the cruise not available and check engine again, sure enough..tape was coming off...replace the hose..problem solved.

It needs a code scanner hooked up to it,to tell you why the light is on and the cause. If there is an autozone near you take it there or
call different auto part stores to find out if they do that.Without getting the code, it's just guessing what the problem is.

It sound like you are having a electrical problem.You need to check your electrical/ignition system,not all electrical problem the diagnostic machine can read.
