Subject: Opening an 059 (5/6/735i) DME
It's easy to separate the boards on an O59 DME...
Follow along with me now...
Once the DME is out of the car, and the metal cover
has been removed by bending the tabs...
Look on the dead center of the metal bottom of the
DME, and if there is a PLASTIC sort of rivet thing
there.. pull the center of it out and remove it..
Not ALL of them have this rivet, so don't worry if
there is nothing in the center of your DME bottom
Now turn it back "board side" up..
Notice how the "back" end of the boards are joined
with a ribbon cable setup..
Looking just to the right and left of the cables you
will see a set of plastic risers that will pop apart
the "left" one usually pops at the top, and the "right"
one at the bottom.. look closely then pop them apart
Now, with the back of the boards free.. pull them as
far apart as possible.. now pull the top board back,
and the front of it will come clear of the connector
and you can "unfold" the whole assembly...
The two boards will be side by side, connected by
the ribbon cable assembly..
Chip is on the board that was the "top" board
and is the ONLT removeable chip there..
It's either a 24 pin chip numbered 1 267 355 169
or 1 267 355 206.. or a 28 pin numbered 1 267 355 353
