SOURCE: INSTRUMENT CLUSTER
The red electrial connector on the main circuit board (of instrument cluster panel) has one and/or several soldered pins that have broken away or become loose at the soldered area. The soldered connections may look o.k., however, under a magnifying glass you can see a circular crack all around the protruding soldered pin. Fire up the soldering iron- use a fine point, add a tad of new rosin core solder and fix the crack. There may be trouble codes associated with this condition: P1695 and/or P1698; when you go to pull the Instument cluster out of the dash, jiggle to wire connector at the back of the IC with key 'on', and look at the odometer; if it flashes on/off, this is most likely the problem

SOURCE: instrument cluster not working
no other way to solve it but replace it, sad thing is no second hand clusters available (in Manila). Purchase directly from your Mercedes Benz dealer. This will solve your problem, in a quite costly way.

You need to find a code book or someone who can get their hands on one. Usually a parts house can tell you what a code stands for.

The IPC detects a loss of serial data communications with the BCM.
The BCM detects a loss of serial data communications with the ECM.
This you should take to a ASE qualified repair facility or the dealer ! It is possible to short out the data bus an bring down the system , meaning nothing on the vehicle will work !
