Hi, I have a 2000 W210 wagon and a few months ago a neighbor spilled coffee down over the console and of course screwed up the shift module circuit board. I was lucky and washed it down with contact cleaner and dried it out and it is working now. (wonder how many are changed unnecessarily) Anyway, I am not sure how long it will last but I figure if I buy a new one I may try to modify something to avoid this again. I have a product that we use at work made by Wurth that is a clear spray coating for just that, electrical boards or contacts,wires or anything else. Just spray it on and it puts a thin transparent film over the board that can be peeled of like a bad sunburn. This would stop coffee or most anything from shorting out the board if some unfortunate soul was to be somewhat clumsy on an off day. My question to the forum is: Has anyone ever tried this stuff or something similar? Has anyone tried another method of protecting their inheritance from going to shifters? I really hope there will be some response on this. I don't have much luck with getting questions answered that are actually beneficial, there seems to be more time spent on " how fast will yur care go" or " Who has done the most mods" or similar threads. Not complaining, just sayin'
