Modul MPM
e61 - k čemu je modul MPM ?
Zdravím,chtěl jsem se zeptat,zda nevíte,k čemu slouží modul MPM umístěn v kufru u E61,napršelo do něj.Dík.
Díky.
Ale nedalo mi to, tak jsem strávil na gúgli trošku víc času, abych se přiblížil řešení mého problému a tady trošku podrobněji:
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.

Re: Modul MPM
Poňadž vyhledávání tohoto serveru je marné a pod "MPM" nenašlo žádné příspěvky a paknějak maximálně tohle updatnu ho.
Problem sekání zvuku radia po startu a/nebo restartování iDrive M-ASK obrazovky jsem došel, jako mraky majitelů E60/E61 k téhle příčině. Energy test na diag. navíc ukázal MPM jako failed communication. Tenhle popis se může ostatním hodit: https://www.youcanic.com/u/bmwadict/bmw ... m-problems
A třeba návod jak předejít jeho zničení : https://www.youtube.com/watch?v=ey0fzyyGTnU
já to už asi nestihl
bo jsem nějak netušil že ho tam mám. 
Může to mimojiné způsobovat vybíjení baterie a neuspání auta což je můj druhej problem.
