OFFICE MEMO RE> Dead Motronic & Rant Date: 10/3/96
This is a two part message. The first I hope will help Anthony Le & Dewey M.
Sasser in their search for Motronic fixes. The second part is a major rant
aimed at BMW/Bosch.
First off, some of you will remember that I had a problem with my 1985 635CSi
not starting. I had the same problem as Dewey. Wouldn't start, or would
stall soon after starting.
I checked the fuel supply & various relays. No good. I took out my Motronic
1.1 computer (the one above the glove box), opened it up to look for anything
obvious. Again (I thought), no good. Reinstalled the Motronic, and the car
started then died a few minutes later. Pulled the Motronic out again, took it
to work (good soldering station) and gave it a very close look.
The board was manufactured in 5/85. The receipts that came with the car said
$1,100.00US had been paid for a rebuilt Motronic in 1992. The large metal
transistor had been replaced at that time. After checking the whole board
carefully, I focused on the solder connections of the transistor. Sure
enough, 2 of the 3 were bad, I reslodered these and so far I runs well.
So Dewey & Anthony, you may want to take out your Motronic units and look for
a bad solder joint. You may save some money.
Part 2: What I found in my Bosch rebuilt Motronic unit...
What an over priced pile of SHIT! The parts the Bosch used were cheap
Philippine junk. There was about ONE+ onces of dried flux stuck to parts and
several borderline cold solder joint. I've seen better quality in a $30.00
Kragens EI control module. When I spend $800.00 on a part, it better be AS
GOOD AS NEW! If the unit Bosch sells is any indication of the quality of
their remanufactured parts, then Bosch will not get any of my future business.
I am very disappointed in both priced and performance. The rebuilt unit
should last 10+ years.
Rant mode off.
