Which one of these products works best on Hyundia 2.0 GDI engine with 70k+ miles on it? Does each of those have benefits over other?
Edit: I meant BG Platinum® 44K® Fuel System Cleaner
The mykey premium remote start on 2019 Sant Fe push to start does not do the 4 beeps after power up. It does the initial 2 long and 1 short beep but then it does not move on to 4 beeps. The dip switches are setup properly as per remote start recommendation, the wiring harness are hooked in all the way, there are no broken or bent pins in harness or in CAN bus connector. The battery ok keyfob was changed. It was working for months and then suddenly stopped working, there were no changes on the auto electrical or wiring or anything.
Has anyone had this problem or further troubleshooting steps to do?
