(Pt 2) Benz DESTROYS Battery...Liftgate Can't LATCH?? ('07 Mercedes ML320 CDI)

In Part 1 we discovered that the Power Liftgate FAILURE and the massive BATTERY DRAIN were indeed linked on this 2007 Mercedes ML320 CDI. Looks like WATER got into the Rear Signal Acquisition Module (Rear SAM) and made a MESS!! Is there any alternative to REPLACING the expensive Rear SAM? I found several videos where people actually CLEANED the corroded circuit boards and brought them back to life! There's nothing to lose really, and we could potentially Repair the car No Parts Required and save the customer over $1,000 and WEEKS of downtime. Will the Magic DeOxit save the day?
