Hey guys, just picked up my second fc. It's a series 4 and the previous owner has put a full 3" exhaust on it, including a brand new cat but the temp warning light for it is constantly on. I'm assuming that they have just left the sensor disconnected. Whats the best way for me to get this light to turn off? I was searching but my computer died and I only have the iphone so I figured I would ask. Thanks in advance
