I think you need to be more specific with what light it was...

E.G. was it this one?



I presume so?

Best thing to do is to hook it up to VAGCOM, there's little use speculating as to what the problem is, it could be a number of different things  :smiley:

If its just a light and the car is otherwise running fine it will just be either a faulty cat, or second lamba probe, if your running milltek etc, then its not a concern, if your running standard, its a good excuse to upgrade, if you want to never see that light again, go Revo stage 2  :happy2:

You could try ringing the RAC/VW assist. They should have the necessary to read the fault codes.
Without that it is just speculation.

I also had the same symptom after revo/fuel pump was added.
Revo confirmed it was indeed a CEL issue which can be rectified by upgrading the exhaust/down pipe.
You may still wish to get things checked with your local revo chappy for peace of mind.
