Hello all, I just picked up a 2019 330i a few weeks ago. I am the first time BMW owner. Three or four times now I tried to show my neighbors and friends how fast the car can take off by stepping hard on the gas so that they could feel the car pick up. I did this only a minute or so after starting up and driving out to the main road. Then lately I have read that doing so would cause damage the engine and transmission, especially when the engine is still cold. Have I already done some damage to the car with my stupidity that I am not aware of? Thanks for your input.
