Question about 2004 Volkswagen Passat
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 ?
I had this problem myself and was told it could be one of 3 things
1. ignition coils are on their last legs and would need replacing (there are 4 of them in a VW golf)
2. The throttle housing is knackered and needs replacing as it has caused the motor that powers the accelerator to stop working and
3. The catalytic converter has an excess of carbon stored within it and has caused a defect.
All 3 of these jobs are notoriously expensive. Much to the delight of whoever it is you have gone to see....

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.

I have the same problem with my 2000 vw gti. at times while i am driving, this 'emission workshop' light goes on for a second. is this a big problem or am i free to drive it around for a while?
