Check Engine Light- Reduced Power
First post on here and unfortunately its a problem that hopefully someone can help with. Currently have Downpipe Back Street Performance Exhaust, and Injen DCI ( SP1125P). Lately, have had a weird/low idle and overall the car has been running different. Today, a check engine light came on and severely lost power, I think it went into what's considered limp mode? Also, when I checked under the hood, it was extremely hot. 1. If anyone has any idea of what might be the issue, and 2. Im worried if I take it in, BMW will void my warranty. Any help would be greatly appreciated. Thanks!
