BMW X4 DAB Radio and Audio System Problems? Solutions Here

I have some experience with BMWs. Had a similar issue with my 2012 X3, and my sister owns an X1. The symptoms you're describing sound exactly like what I went through! The reception was terrible, and eventually, the whole infotainment system started acting weird. Turned out it was a faulty antenna, these things can go bad over time. Took it to my regular workshop, and they diagnosed it pretty quickly. They had to replace the antenna module completely, set me back about 255 Euro, but it fixed all the problems. Now everything works like new. What's your mileage? And have you noticed if the issue gets worse in certain weather conditions? These details might help confirm if you're dealing with the same problem I had. Quick tip: Don't wait too long to get it checked, these issues can sometimes affect other connected systems in BMWs if left unaddressed.

Thanks for sharing that info! My X4 just hit 46398 KM and had its latest service a few months back. The symptoms you described are spot on, the reception issues do seem worse on rainy days. Good point about not waiting too long. Think I'll book it in with my mechanic next week to check that antenna module. Really hoping it's just that and not something more serious with the electrical system. Did your workshop mention how long the repair took?

Oh yes, I remember that thread! Let me share more details about my experience. The repair on my X3 took around 2-3 hours total. Most of that time was actually spent on diagnostics and testing to make sure the antenna module was definitely the culprit. The actual replacement only took about 45 minutes. And funny you mention the rain, that was exactly how I first noticed the pattern! The reception would get really terrible during wet weather, then slightly better on dry days. Classic symptom of a failing antenna module. Since getting it fixed, I haven't had a single issue with the infotainment system. It's been about 18 months now, and the DAB reception is crystal clear. My mechanic mentioned these modules typically last 6-8 years, so the timing made sense for both our cars. One thing I forgot to mention in my first reply, make sure they check the connections too while they're at it. Sometimes moisture can get in there and cause corrosion. My mechanic cleaned all the contact points during the repair, which probably helped with the overall performance. Hope this helps with your decision! Let us know how it goes after the repair.

Thanks so much for all this detailed info! Really appreciate you taking the time to explain everything. That's actually super helpful to know about the repair timeline, I'll make sure to let my mechanic know about checking those connections too. I'm feeling much more confident about getting this sorted now, especially since our cases sound so similar. I'll definitely update the thread once I get it fixed. It's great to know that you've had no issues for 18 months after the repair, that's really reassuring! I was worried I might be looking at a major electrical problem, but this sounds way more manageable. I've already called my mechanic and booked it in for next Tuesday. Thanks again for all your help, this is exactly why I love asking fellow BMW owners for advice!
