M.I.D infor missing.

Relating to my other post which is fizzling out (K-Bus Down) I have got most functions of the car back now after all my modules stopped communicating and controlling the car when the battery absolutely flattened

Using BMW Scanner, TV and MID modules are some of those modules not found.

My LCD is displaying satnav, radio etc but the TV has disappeared from the listing on screen

Also on the binnacle......I have no MID info controlled by the end of the indicator stalk.
ie no time clock , consumption, stop watch, fuel miles left etc....

The dot matrix display DOES work because I get the FASTEN SEAT BELT message if I forget displayed on that's just the auxillary MID info which is missing.

Lastly and may be connected.......the doors dont auto lock even though they are programmed to according information accessed by BMW scanner.
The doors do auto lock and move the windows up and down with the key fob but not when the car reaches 16km/h as programmed. TV fuction available, no auto door lock when speed achieved, no MID info displaying / avaiable.

I would say BM54 Radio unit and TV module in the boot are at fault. Issues are not unknown with these units. There are specialists who repair the BM54 unit but TV units I am not sure.
I had this issue in my 4.4 the cost of repair/replacement of the two modules even back then was high so I put in a Dynavin unit that had Radio, Digital TV, Bluetooth (much better that OEM) Nav, Ipod connection just better. I sold the OEM Nav
, CD changer and Headunit and recovered most of the cost of the Dynavin. I am told that the new units include mid operations.
If things start going on the 4.6 I would go that route again

I think members on here have used Cartronics in the past and been very pleased. It is possible to have the BM54 upgraded with things like Bluetooth streaming but I don’t know the costs sorry.

I reckon its the TV module.
Radio is displaying all stations and listing the stations OK.
One thing I noticed when working in the boot on was that inside the TV module, there is a cooling fan and this constantly starts and stops about one minute intervals.

Not sure what this has to do with the MID information though or the doors not auto locking at achieved speed. ?

Door locks are controlled by the General Module that appears to be above the glovebox. Each door has its own actuator controller.

Newtis shows this: ... es/EXZUSLP For left hand drive cars hence assuming it will be over the other side on RHD cars.

I can’t think of an obvious connection between the MID and locks either unless the water in the rear is/has resulted in trouble in the wiring loom and either a short or bad connection. If anything is upsetting the bus because if that then it may be taking out other unrelated modules. My thought process is whether the tailgate lock wiring passes through the wet area? There’s a lot of wiring down by the battery and modules in the carrier beside it.
