'Emissions Workshop' warning light

6 posts in this topic

The 'Emissions Workshop' warning light on my 1.6 16v '03 Golf keeps lighting up. At first, the warning light flashes whilst the engine is clearly misfiring, then after several minutes, the light will remain on and the engine will appear to run ok. The car has been back to the dealer four times in the last 10 days to have it sorted and within a few hours of collecting it from them, exactly the same thing happens again. All the dealer seems to do is change the coil packs and the EGR valve. Other than that, they seem to be at a total loss as to what to do.

Has anybody come across this problem before and if so, what's actually wrong with the car as the 'fitters' at the dealer clearly haven't got a clue.

Any help or assistance is much appreciated.

Hi; i have a MK4 Golf 1.6 SE 16v (02) and got the same problem. My local vw specialist is struggling ti fix the problem; the light comes on; the car miss fires starts driving real slow; i switch engine off wait and restart; then usually missfiring goes away; then light goes away. My mechanic does the diagnostic test; it always says plus 2 miss fire. i have changed all the coil packs, put new spark plugs in still the problem occurs. then my mechanic said it was the temperature sensor; put it in did not work; waste of 30 pound. Then he said it is the lampda sensors also known as oxygen sensors (cost 230 for both) put them in last week; still not fixed; taking it to him again tommorrow; he gonna try again. i dunno whats wrong; he said to me he confused to whats actually wrong; any luck let me know what was changed; i will do vise versa if i get somewhere tommorrow. good luck

Hi, check the cylinder compressions, carry out a cylinder leak test and check the oil pressure. I am not telling your mechanic how to suck eggs but remember to keep it simple and don't forget the basic engine fundermentals. 169144-ok.gif

I had this problem. It caused my car to completly stop and not restart, several times.

After going back and forward to the garage, it turned out to be the EGR valve (something that recurculates the exhaust emmisions). Turns out i had small slithers of metal caught up in the piston of the EGR valve. Since picking these out i have had no problems. Hope this helps.

Tried the above for my golf mk4 1.6, Car judders when accelerating could this be the coil packs on each spark plug.
