Hi, When I turn on the ignition the display shows Emissions workshop. I had the car serviced recently and had this problem before servicing. I mentioned this at the time of the service but the diagnostics never highlighted a problem. This is an intermittent fault. I may use the car for three days or so without the warning appearing and then it may start again. I spoke to the garage about this and they feel this may be caused by a faulty unit but were not sure. Do you agree with this prognosis ?

Re: Emissions Workshop on display
Sure it may be due to a faulty emission sensor or to another problem of this kind with the emission diagnostic (a short, faulty instrument panel pcb etc.). the way to know this is assessing the emission when the warning light is on. Ask to your mechanic to perform a new test when light is flashing, and eventually test instrument panel and emission sensor, in case emission is ok.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

You need to have a scan of the engine done There are a number of problems that could cause those symptoms. Ask your repair shop how much they charge for the scan Our shop does them free, some shops charge. Get a copy of the scan results and have them clear the codes. Than ask for quotes on the repairs.
Not being able to turn the steering wheel at all starts at the ignition lock locking the shaft under the steering wheel. Next if that is ok then it indicates a serious problem in the rack and pinion or the flexible joint to the rack/steering box. As this is a safety issue I would put it on a tilt tray and have a accredited steering repair shop investigate the problem. Check the power steering pump drive belt is still intact
In your particular car have complete computerized assist plus service system, the information regarding next service your mechanic have to read by instrument cluster display, it give you workshop code for next service and all other impotent details, then your mechanic have to put it in to the Mercedes workshop information system and the system say what's the next service it's depend on mileage, over due or remain mileage over due or remain days, and service code and workshop codes, otherwise can't say what's need to be do in your particular advance car, this is the best way to protect your car, is this information helped you?
Emissions Workshop means that the fuel / air ratio is incorrect. There
are many reasons for this problem. The ONLY way to be certain is to
have the OBD codes scanned. This will show the problem straight away.
If the car appears to be running ok, you may have a problem with an
oxygen sensor....but do the scan first. It is the quicker and cheaper
Good luck with it
"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!!!
