Scan of the codes is the only way to see what the cause is, as it could well be totally unrelated.

Yes i guess it could be unrelated but seems a coincidense that it came on on the short drive home from getting it fixed, anyway like you guys said scan with vagcom next, i messaged the garage and they said their vagcom is playing up and "We don't use vag com at the moment as our cable has decided to play up. If the exhaust isn't on the map and it's got decat it wouldn't usually just go away if reset
Some people space the sensor to give false reading to take the Light off" - to which i replied is has a sports cat, and also the car was mapped with thte exhaust on :s

Mapped by who? There's a big difference between being mapped for a de-cat, and having it remapped after fitting a sports cat..... If you had a sports car fitted its likely that the mapping that monitors the cat efficiency wasn't changed.... Their efficiency does degrade with time

Wait until you get the codes read, then clear them, and see how it goes
