2007 525xi electrical issues

[fbrider]

My son was driving our 2007 525xi today and it started having electrical issues. The wipers are coming on intermittently and the radio keeps shutting off. We've had the car for about 6 months and we did have to replace the battery early on. It has about 110k miles on it. Any thoughts before i go look at it?

I will move it to the 5 series subforum, did you check the alternator voltage?

Thanks. Turns out it is the TPMS module that sits in the bottom of trunk that got wet. Any suggestions on where to get a module, as well as why i got water in my trunk?

Water in the trunk is a known issue. There was even a recall on it. Do a forum search.

I put in a new module and relocated it above the flood zone It was plug and play and all is good now. Also found a great source for used BMW parts about 30 miles from my home!

Check your mpm in the trunk.
