Re: <e28> Motronics question (fuel pump relay control)

[GRobWorkII@xxxxxxx]

Peter,

   For safe measure, you might try replacing the main and/or fuel pump relay 
on the side of the fuse box.  (It cannot hurt.)   Has the car been chipped?  
The more friable components in the DME can be damaged by impatient, 
overzealous, performance-hungry DIY software installers...  If the problem 
DOES lie within the DME unit, there are a few options.  You could purchase a 
used unit (potentially full of the same monkeys which currently live in your 
glovebox), ship the DME out to be rebuilt (Programa is a popular provider of 
this service), or, if you're handy with a soldering iron, carefully crack the 
little bugger open and have a look-see...  I've heard more than once that you 
may find (and more importantly fix) cracked/broken solder pin connections on 
the circuit boards.  Many folks have reported success in this arena...

Hope this helps,

 My 88 535i recently had a few episodes of stalling out and failing to
 restart.  As a last ditch attempt to start the car, I gave a few taps to
 the Motronic unit in the glove box, and the car started.  It later stalled
 again, but restarted after the Motronic was tapped.  Has anyone had this
 problem?  What must I ultimately do to keep this from recurring??
