Lightbulb Check Engine - 05-09-2019, 01:45 AM


After installing the JB4 on my Cooper S i keep getting the Check engine light up (orange ) , i am using map 2 , car is running fine . i can reset it using the JB4 but it come back every time. Before the installation never had it, is it normal ? safe to keep on ?
