BMW E36 / E34 ECU 

Up for sale is this BMW Bosch ECU.  Part number  0261200405 / 1735614 

This works with several models/years but as usual check your part number to be sure it will work.

This is one of the most common no start or random stalling problems with these ECU's. If yours does not have this problem, keep an extra ECU in the trunk, you might some day be glad you did... These units now have to be special ordered from most dealers new for big $$ (often times over $1000!), and finding a good one second hand is getting to be a very hard chore.
