Guys kind of off-topic not actually uploading any JB4 times.
But I got my car like an year ago and it still has like 1 year and 8 months of full warranty.
So I talked to my bmw dealership where the guy is really a cool guy and I asked him would I have any warranty problems if I go for JB4.
He said something about newest bmw's like MY2020+ are sending all kind of data OTA and it will "probably" mark my car as tuned and thus will void my warranty if anything happens to my engine or gearbox.
Does someone of you ever had experience with having an engine issue and jb4 installed?
Is this just a bmw trying to scares me off? Or it is a real thing... I really want to tune my car I just feel it a little bit weak after 70 mph, my last ride was a V8 supercharged car with 500 hp and 800 nM.
