Repair mercedes sam module at pc shop?

Actually i have an 07 mb e350, w211 body type, wasn't listed in drop down box. Trunk got wet and fried sam module/ signal acquisition module. This controls all car functions and are 3 of these which are connected to a fuse box on each. Can a pc repair shop do this repair. If the original from the car is repaired there is no need for any programming from a mb shop with the star diagnostic system. There are shops that do this but none near me. Also i believe at least 2 of the 3 of the sam modules have been affected. The other not by water but an improper battery change. Excessive arcing when connecting or disconnecting battery is apparently another main cause. My systems are all showing the tell tale signs, dash buttons and radio not working, system malfunctions on multiple systems etc. So would it be ok to ask a pc repair shop to perform this. I read a 64 pin, chip is the root of all this and bad design. Its just a computer board. Not a pc but i assume all the same components go into most circuit boards. Thank you. New sam units are expensive and still need programming, used would work if from exact same model but still need programming. Also most come from totalled vehicles which could have the same problem. Thanks, John.
