I've been having issues with my ECM because of a leak somewhere near my windshield, cowl, etc, that I cannot locate. This causes moisture at the location of my ECM and causes ECM to fail, i.e. bad signaling to fuel systems, run rich and others. I've replace my ECM to solve the issue (runs great by the way), but I am trying to see if there are any recommendations to waterproofing ECMs. I read this thread in another Landrover Forum. Have anyone heard of this or have another option?

You could do conformal coating.

Just DO NOT get it under the chips. It will cause jacking with thermal cycling and break solder joints.

Also these ECMs are very old now. It would be wise to replace all the capacitors before coating.

But really you should fix the leak. Everything else in the car is also going to be subject to corrosion with the elevated moisture levels. Plus mold.

 

Thank you so much for the fast reply and guidance. I definitely am seeking to address the leak. I think it may be the windshield, cowl, etc and trying to find window shop or body shop to properly address it.
