What if it was erased? I'm in winter-mode now so the car is slow and sluggish and I can't feel differences really.
It should say in your paperwork if they updated the ecu for any reason. You can always double check by calling your Service Adviser and have them verify if it was updated or not.
If you do not have a simon tool you will have to send us the ecu.
