VW Polo Exhaust Emissions Light

[miln0039]

I was driving my 2001 Polo 16v in town earlier, and my Exhaust Emissions light lit up (for the first time!). I checked the manual, which naturally told me to give all my money to VW, so ignored that and drove the 7 or 8 miles back out of town. The car seemed to suffer no change in performance, and I couldn't notice any difference in the sound - and have had a brief look underneath and see no noticeable damage to the exhaust etc. I'm quite confused as to what the potential issues could be, but I would assume them to be minimal seeing as the car came through its MOT less than one week ago! The car has covered 68k miles and the cambelt has been changed, so other than that I'm pretty stumped as to which of the potential problems listed above it would be advisable to check first?! I had been running the car on BP and Texaco petrol, and only in the past week have used Sainsburys, maybe this is a reason? I'm on a student sized budget, so willing for any money saving techniques there might be too! I would be most appreciative of any advice possible!

Many thanks!

It would seem we are all having the same problem all at the same time...weird!?
