The 225 comes with a turbo timer that runs coolant through the turbo after the car has been shut down. The 180 does not have this feature so it best to let it cool down for a minute or so after heavy driving before turning it off.

Gene adds: "If you are using the 180hp TT then yes it would robably be better to get a turbo timer for 'peace of mind' whereas the 225hp does run coolant for the turbo when you turn the car off. several brands are considered good such as apexi pen light turbo timer which is discreet and stylish or Blizt DTT turbo timer which automatically calculates the time needed to cool the turbo down."
