So last night I left my trunk open and it rained checked the spare area and my RDC (tire pressure receiver?) and my MULF2 HIGH(idrive) module were completely submerged. Now when I plug them back in the headunit doesn’t work completely it works for a bit then freezes and doesn’t let me select AUX and doesn’t have Navi signal. SOS does come up on the dash but not anymore sense I brought a heat gun to the MULF2 module but the headunit issues still occurs. Im not sure if replacing the module would fix all these issues. if any knows about these systems please let me know

 

Why would you run power through something that is wet? I would of dried it first before I attempted anything. Now that it's ruined the module needs replacing. If you are DIYing this the the module will need to be program and coded before it works. I would advise taking it to someone who knows what they are doing.
