VW Golf Emissions warning light - dazzler
I have a 2000 W Reg Golf 1.6SE and have been having constant problems with the Emissions warning light coming on for a couple of days then going out for a couple. The light is amber and doesn't blink. It has come on when the car has been stalled on a couple of occassions, but also when the car seems to be running fine. The only other symptom seems to be a occasional slight misfiring.

The problem has been happening since VW put a new speed sensor in. Although I don't know if this is related.

I have had the throttle body cleaned, but the light has still come on again. VW told me I would need a new throttle body, but I'm not convinced that this will solve the problem.

Does anyone have any ideas???

On my 2000W Octavia it was caused by the MAF (Mass Air Flow) sensor. This is a pretty common problem on VAG engines. The part is a standard Bosch part for VW / Skoda / SEAT / Audi and is probably cheapest (<£100) from Skoda or SEAT. Might be worth a try. Another possibiitiy that I also had occur on the Octavia was a perished vauum hose contolling the EGR. This let excess unmetered air into the manifold which caused the light to come on.
