I’ve left my sunroof open multiple times in the snow. The notification has saved me about 5 timesCar net wasn't worth it to me. Although during free trial I once got a text from my car saying it was raining in the area and my windows were down. I was impressed, however it was in my garage at the time
I imagine it's the same as Hyundai Blue or whatever it's called. You get a CEL and they will know immediately. My Veloster came with it for the first year at no charge. Of course I had it tuned, DP etc and the first time I got a CEL I got an email asking me to make an appointment to investigate the CEL. I canceled the free year.I'm sure it tracks but has it ever been proven that it sends data to vw?
