If you havent go the DME from the dealer, i recomend you to try something first. sometimes it works, sometimes does not.
Get the DME, put it on your bech or a surface.
BEfore opening the DME get yourself electicaly discharged, so touch a metal surface and keep touchin git, like with you feet.
Open the DMe metal box and with a hair dryer star blowing hot air on the circuit board, dont worry sothering tmeperatures are hoter than a hair blower, so keep blowing to help dry the board, then get contact spray cleaner, that one used for electronics, spray it all over it, this thing dry up any moisture on the surface of the electronic board.. on aircarft maintenence they use freon, because when liquid freon touches the metal surfaces of electronics, it instantly boils and evaporates burning any moisture that it has..
do this above, reasslemble the unit and plug it in, then try firing it, migh work or not.
also if youre using an independent shop to do this job, chances are they would not be able to do it, because they need BMW computer, known as modic.
Since the DME has to be coded with the mileage on the dashboard, they both have to macth and since youre car has the central locking system, the key and the locking system must be codec with the DME and only a dealer has acces to this computer, unless your shop guy can gey this from a dealer, then he can do it. otherwise call the flat bed truck and send to the dealer to get programed once the part is in.. yes it sucks...
I really hope one day the modic programs are on the net, so with a few wire some plugs we can make our own wires to use on the laptop.. Dont forget Modic is a regular computer runing windows with BMW software to code the cars..
Going back to subject.
But before even getting the other unit, think about one think, how did water get there, very simple
where the air intake for the ac is, which is that little plastic grill on top of the engine, there are drain in there to drain the water from the windshield. if the grill is broken or not well in place, leaves and other natural crap gets in there, clogs the drain ports. then you make a heavy turn one day and voila the water runs sideways and enter the DME housing box. and if you ask, would the water enter the ac box, yes it can, but if this happens it would end up being drained by the ac evaporator drain inside the box. so you dont notice.
General rule is, make sure yo pick the residues on the bottom of the widnshile and trown away, and whenever youre checking oil and stuff, pop taht grill open and see if there are things in there.
yes is a thing place, but there are 5 screws, take them out and the metal part where the grill goes onto comes out so you have a big acces to the blower housing and drain and all the stuff underneat the windshield.
