F55/F56 JCW Pro Exhaust and disconnecting battery....will it cause issues?
JCW Pro Exhaust and disconnecting battery....will it cause issues?
Hi all,
I've got an F56 Cooper S with the JCW Pro exhaust and bluetooth switch.
I'm planning on doing some work to my car which requires me to connect the car's battery.
I'm just wondering if anyone has had any problems with the exhaust/bluetooth module and syncing after disconnecting the battery? Or should I expect any issues?
Thanks!
