Successfully added Traffic Jam Assistant to US model -- interested in other people's experience with TJA

[I3drivei3]

I just had Premium Retrofit code my 2015 I3 for lane assist and it works great. I did have to buy the module from them and easily installed it behind the steering wheel in about 10 minutes. Yes, many of your Bimmercode programming will be erased, but you can easily recode. Premium Retrofit stated that they will reprogram for free if the coding ever gets erased.
