MK4 GTI Turbo Exhaust Emission Warning Light

Just came on on my journey to work.
Anyone have any idea what this means or what it is likely to cost to sort?
In my manual it says take straight to dealer to get the engine checked!

Thanks,
Gemma.

Clean the MAF (airflow sensor) in the airfilter housing with some electrical contact cleaner. Often cures it.
You may also have to disconnect and re-connect the battery too as not sure if it is logged as a permanent fault code or not.

Could also be a coolant sensor. Very common. Best idea is to find someone with VAG.COM and read the fault

Could be an endless list of things, need to get the code read on VAGCOM really.

Could be coilpack, MAF, coolant sensor, lambda probe, broken DV, boost leak, vacuum leak etc...
