I have received the K+DCAN cable and managed to download the complete trace settings from my car. Since it is a second-hand car I was not sure if the BT had been properly enabled but reading through the settings I believe it was (BLUETOOTH_RAD2=active, ULF_ECE=active, PHONE_TYPE=mulf_sa644, etc.). There is this one setting that seems odd and that is "BLUETOOTH"=not active, however, I did not find any relevant information about that particular setting in any coding forums. My secondary problem with the non-beeping PDC seems similar, some settings are active but the one named "PDC" is not active. If anyone with a working BT and/or PDC on a car with Professional Radio (no iDrive) and MULF could share with me their complete fsw_psw_trc file, I would really appreciate it.

I will give it some time before I conclude that my MULF is really dead. Then I will try to troubleshoot the electronics of it myself and if that failed I would probably go buy one of those touch screen aftermarket HUs.

Just came across this post - had the same thing happen to me and replaced the Visteon unit with another from ebay and it failed a year or so later. They are crap units.

Strongly suggest retrofit a MULF2 unit - made by Bosch, lots more available and the process isn't hard - slight connector mod, a little coding and away you go.
