Plastic bag round the ECU?

MissMoppet · 10th October 2020, 20:21

We all know by now that the Big Fault in our cars is the dreaded drowning of the plenum and saturation of the ECU. While I have bored Arctic's Hole and rod when I remember there's always the lurking suspicion that it may submerge. Which leads on to the question: is it possible/advisable to wrap the ECU in a stout sealed bag as an added precaution?

I have read of there being an atmospheric sensor inside, someone will be alone I am sure to confirm, but if there is, a bag will give false readings

Correct Cliff, the best way is to clean the plenum, rod the drains then fit one of Jules' plenum guards or put some foam in each side of the plenum to stop debris entering the drains.

Yep done all that, just seemed the obvious next step. Ta.
