I'm thinking ask google or utube

This is a mileage interval light that trips every 3,000 to 5,000 miles that indicates an oil change is necessary. You do not need a special tool to change your oil, nor do you need to bring the car in to the dealer.
1. Sit in the driver's seat of the Passat and close all the doors.
2. Position the trip/odometer button to display the odometer mileage reading, then hold it down with the forefinger on your left hand.
3. Turn the ignition key to the "key-on/engine-off" position to turn on all the power options for the Passat without actually starting the engine. At this point, a service indicator light will display (in the form of a wrench).
4. Press the minute adjustment button on the clock (or turn the knob clockwise on European manufactured Passats) and release the trip/odometer button.
Good luck and thank you using Fixya

dealer only ,might get away with a re programme of the chipped key ,worst case scenario is a new ECU

There may not be any other way to fix it except to replace your instrument panel. That's where your immobilizer is located. Or you could try this:

Try cold-booting the car. Remove both battery cables from the battery. Short the battery cables together (away from the battery) for about 15 seconds. Reconnect the battery. No guarantees - I found this info at tdiclub.com.

sounds like a faulty wire,possible on the ignition circuit or faulty battery leads.

"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!!!
