Hello, welcome. My name is Mike, I will do my very best to assist you with your question. I apologize if you have been waiting long for a response.

What happens when the vehicle reaches 120, shut off?
Customer: replied 3 years ago.

No it does not shut off, it just will not go any faster. My previous C320 would go to about 150 mph and I want to know why my present C320 will not?

Expert:  mike_a_mechanic replied 3 years ago.
Ok with the vehicle not going any faster, at some point a governor has been put on the vehicle to cause the vehicle to max out at 120. The governor on this model is integrated with the ecu and basically to get this bypassed the ecu will have to be reprogrammed, this will be the only way.
