Failed Footwell Module (FRM) after battery boost - procedure to install battery?
Hi everyone,
The battery in my 2012 135i is on it's way out. Earlier in the week, I had to hook up jumper cables to the car to get it to start. After the car started, a bunch of things stopped working: window controls, headlight controls, turn signals, DRLs. All symptoms lead toward a failed footwell module (FRM). I called the dealership and luckily they will be replacing the FRM under an extended warranty from BMW NA. Anyone else have a similar experience?
After I get my car back, the battery will still need to be replaced. I've read about a couple instances where the FRM failed when disconnecting/reconnecting the battery. Are there any precautions (e.g., letting the car fully sleep before disconnecting) I can take to avoid dealing with FRM issues again in the future?
