MULF or TCU

[Jnash467]

I've searched the threads, but didn't find a definitive answer. My sunroof drain got plugged, and my left rear compartment area got soaked in my 2009 X5. The SOS malfunction error light came on. Now my Bluetooth, Aux, and Sat quit working. The voice recognition works, but can't hear me.
My radio, CD, NAV, and I-Control still works. Before I take it to the dealer, do any of you have insight on which box would control what's not working?
Thank you in advance.

In the 09, the Satellite module is separate (but also in the location of the MULF). It sounds like the MULF and Satellite Modules are hosed.

Both are cheap to replace via eBay or junk yard. I bought a MULF earlier this month for less than $100 shipped.

Thank you Sean. Yes, the satellite unit got a lot of water, and it has a very open case. Today my radio cuts out, and the iDrive locks up. I think I'm going to call it into my insurance as water damage. I'm thinking the dealer needs to do a full diagnosis, and let them repair it. My deductible is $250 for comp.

Replace the TCU, SAT and MULF. 3 boxes. Surprised the amp didnt die either.

The problem is that if any of those boxes is on its last legs it can bring down the optical bus and thus will cause a overal fail in the entire entertainment/infotainment system.

Decided to turn it into my insurance since I only have a $250 comprehensive deductible. They will cover it all.
I'll let you all know the extent of the damage. It goes in Tuesday.
