Hi I am giving my tt to my son but I worry the car is to fast for him. I want to limit the speed to 75mph. Does anyone have any ideas on how I can do that.

 

Audi TTs in the US already have an electronically limited top speed. People who want to get rid of this usually go to a tuner to reprogram the ECU (engine control unit.) I'm sure you could also have it reprogrammed to a lower maximum speed.

 

you could set the speed limit alarm, so it will sound off an alarm if he goes over 75 mph. I think it has a log that it goes off too, but not sure about that.
