06 4.8iS w/67k

Driving home and notice phone is not paired. Been working flawlessly for 6 months. Mess around for an hour, read forums and try first to reset TCU with fuse, then removing big connector etc.

No luck so far. I could disco battery but not sure why that would be better than removing connector on TCU altogether.

Anyway, BT with factory steering wheel controls, stereo interrupt is essential for me.

Looks like I will be buying a new TCU sooner or later.

1. Anyone bought one ?
2. As car already coded for TCU, if I buy one will it need coding ?

Thanks !
