BMW needs to reinstall software, requires factory amp
engine malfunction failure and BMW wants to reinstall the car's software in order to debug the issue. apparently they can't reinstall the software, because the factory amp does not exist - it's been replaced with a mobridge pre-amp, helix p-dsp, alpine amps et al.
they also claim to be unable to bypass the missing amp in order to complete the software install.
has anyone heard of this before?
