bmw e39 5-series ecu box water drain part 2 (cleaning)

[@paganiluv9552]

This is helpful! I was starting to remove the ECU box after I noticed the water was slow to drain but got stuck on how to take it out.
This seems like an easier and faster solution. It's impossible to reach the drain hole from the top.

Is it possible to have electric problems when ECU box is dirty? I didn't clean mine.

yes, it is possible when the box plastic is cracked but originally ECU box was designed to be sealed
