I feel like this is a bit too close for comfort here and everyone is going through this same issue one way or another around the same time frame but here, take a look at my thread, it'll help you tons.

Your problem I would say 99.99999% is your Central Locking Control Module which is located in the trunk of your car in the right hand side, the spoiler wing is known to leak through the gaskets and cause water to eventually get down there and sip through the module ( I have NO idea what the heck they were thinking when they put it in there ) but its prone to leak.. I hope you're ready to get your hands dirty, you need to leak proof that spoiler wing and mounting plate because once you replace that module, you'll have that problem again since water keeps leaking in there.. the good news is I've been through this and I know its the module, leak proofing isn't all that hard, here take a look at my thread, this happened to me not too long ago too.

I cannot believe there isn't a recall on this!!!!! its too common now!!
