Okay, I have an update! you guys were certainly right! Water got into the modules and fried the circults. Was told that the Locking Pump Module is fried ( the tech found the circult board fried ) which is odd because the doors still unlock just fine! is that really bad then?? hmmm, and said that the Alarm Module is fried which is the cause of the erratic behavior of alarm going off and whatnot. They also said the Foam Cover that you put the wires through to house is also bad and needs replaced ( which is like $35 bucks for that and they needed to order it which can take a week to arrive. They did have the Modules though, funny huh?? of course, the expensive stuff....

Heres the estimate:

Replace both Locking Pump Module and the Alarm Module $1,761, includes parts and labor, taxes and supplies fee, oh yeah, that also includes the thick piece of foam in that price.

Okay, THEN, that doesn't include "finding the leaks" which I already read thankfully to our member here: fastfunfor2. Who stated that the leaks are located under the fixed srt wing on those 2 o-rings and of course by the fuel tank as well ( is that a for sure area that NEEDS to be worked on or water just goes through the fender but not actually inside the back trunk area where the modules sit? ), now for them to "figure out where the leaks are and then fix them, that can range from $100 to $300 for that ).

Stealership to the max!

All in all, this can range upwards of $2k to fix AND I'm not guranteed they will place my modules in a bag or flip them upside down! lol.

So this is where I am right now.... I'm planning on taking on this adventure and doing it my self. I will follow the instructions, is there a way to specifically find on eBay sellers selling the Modules for our exact one's that we have?? can someone link me? I tried putting in the parts numbers but no one has them listed as the actual title so I need to cross referrence and see which Mercedes Benz models and years actually used the exact same fitting modules that I will need to buy now.

I'm going to see about having the tech disconnect the modules completely so that I can drive back home without the lights staying on and then I'm going to start finding me the parts I need to replace this my self. I've always been good at working on cars so this should be a fun project, a way to continue the bond with my car, and of course SAVE MONEY!!!
