Mate is it the light on the right of the dash lights which has come up? Does the car still feel fine?
This will be he decat light, warning for emissions where the ECU is expecting the exhaust gases to go through a cat but they don't so it's throwing the light up.
Mine pops up now and then but it's harmless.
The error will say something along the lines of 'Catalyst system bank 1 efficiency blah blah blah' - it is very common after fitting a decat and harmless.
It can be mapped out or you can use a spacer in the exhaust system to eliminate it. Vagcom does clear it but it will more than likely come back at some point.
