<E36>ECU filling with water.

[r browne <r_browne@xxxxxxxxx>]

I ws browsing through Import Car Magazine (www.import-car.com) and ran
across a tech article that may be of interest to owners of E36's built
before June 1994.
Appears that the intake plenum cowl for the heater/air conditioning
blowing fan can sometimes get overwhelmed by water, particularly if
the drains at the bottom of it are clogged.  If the blockage is bad
enough, the plenum fills with water, which can overflow into the ECU
box, causing major havoc.  If enough water fills the plenum, it may
also drain into the passenger side footwell, but may go unnoticed
because it ends up under the floormat.  
Apparently BMW has a Technical Service Bulletin out on this (sorry,
dont knw the number) which details the fix, which is to add a third
drain hole.
TSB's can be printed out for free at many major "Auto SUperstroe" type
stores, such as Super Trak Auto (DC Area) via the "Mitchells on
Demand" computers located on the counters..
