Water got into Micro Power Module
#11
i would recommend taking it to BMW dealer and get a price for full repair...
atleast you know what your dealing with. Then search for 2nd units and get BMW to do the labour and programing...

That will cost me a arm and a leg I'm trying to avoid the dealer. I know this forum has help a lot of members from taking a trip to the dealer. I have faith in this forum.

i like knowing what to beat when it comes to things like this.
BUT, this forum is a fantastic resource and the guys here should pull something together

Are you sure its not just the lack of programming of the new module? I'd look into that before you go replacing more (expensive) parts.
I've had a problem, where a leak damaged the AWD module and the servo-motor - OUCH! That whole thing got covered under my comprehensive insurance though, so check with your insurance and if its covered, take it to the dealer and have it fixed up proper
Good Luck, Bro! Hope you get her back to 100% soon!

I also had an MPM replaced and needed to have BMW program the car... seems everything needs the dealer magic!

My uneducated guess is the MPM has to be programmed back into switch-on position.
https://5series.net/forums/gallery/i...-power-supply/ pg. 43
How it works
The micro-power module (MPM) enables consumers to be switched off in a defined manner if a fault develops while the
vehicle is out of use. The MPM is linked with other control units in the vehicle to allow it to transmit and receive CAN
messages via the K-CAN. The MPM has a bistable relay which controls terminal 30g-f. If the MPM detects a fault, the
relay will switch terminal 30g-f off. The reason for the deactivation will be stored in the MPM.
The following consumers are connected to terminal 30g-f:
- Multi-audio system controller (M-ASK)
- Car Communication Computer (CCC)
- CD changer (CDC)
- Japan navigation system (JNAV), Korea navigation system (KNAV)
Conditions required for switch-on
The switch-on conditions for the bistable relay are:
- Battery connected
- Vehicle unlocked
- Change in condition of door contacts or boot-lid switch
The MPM is woken up by activity in the K-CAN. After being "woken up", the bistable relay returns to the switch state it was
in before it was "woken up".
Conditions required for switch-off:
The switch-off conditions for the bistable relay are:
- Off-load current too high (more than 80 milliampères) and battery's starting limit reached
- Undervoltage
- Permissible number of "wake-up" actions in K-CAN exceeded
- Bus active after 60 minutes with terminal R OFF without any switch-on conditions being satisfied.
The time is reset by switch-on conditions, e.g. by a door being opened. This means: The vehicle is unable to go into
sleep mode after terminal R is switched OFF.
There is no limit to the number of times this process can be repeated. It could thus cause the battery to become
discharged!
The MPM goes into sleep mode approx. 1 second after the K-CAN goes into sleep mode. Before the MPM goes into sleep
mode, the current switch state of the bistable relay is stored.
