BMW 3 Series (E90 (2005-2013)) With N55 Engine: Troubleshooting Car Radio Not Working

Are you are a proud owner of a BMW 3 Series (E90) featuring the N55 engine, but struggling with a ‘mute’ car radio? Don’t worry! Your favourite soundtrack can soon be playing again with our comprehensive troubleshooting guide.

Understanding The Importance of a Working Car Radio

The car radio is more than just an accessory for entertainment and infotainment purposes. It significantly contributes to an enjoyable driving experience, especially on long rides. It is essential to diagnose and address the issue as soon as possible when your BMW E90 car radio stops working.

Symptom: Car Radio Not Working

The symptom is pretty straightforward – you get into your car, start the engine and your radio doesn’t power on. No sound, no display, nothing. Or maybe, the radio turns on but no sound comes out from the speakers. Either way, it’s frustrating and needs to be fixed. Let’s look at some common causes and solutions when your BMW E90 car radio stops working.

Possible Causes and Solutions

Blown Fuse

One of the most common causes for a non-working car radio is a blown fuse. Locate the fuse box (check your car manual for its exact location) and find the fuse for the radio. Replace it if it’s blown. If it blows again immediately, this could be a sign of a more serious electrical issue, and professional service may be necessary.

Wiring Problems

Another common issue is a loose or disconnected car radio wiring. The wires could have been nudged loose or disconnected entirely over time or maybe due to a recent service where dash components were removed. In this case, it could be as simple as pushing the wires back together, but sometimes a wire replacement might be necessary.

Speaker Issues

Problems with speakers can result in having the radio power on but with no sound output. This could be due to a disconnected speaker wire, a short circuit in the wiring, or the speaker itself could have blown. If you’ve cleaned the terminals and reconnected everything but the problem persists, you might need to replace the speakers.

Software Problems

Like any technology, software problems can occur in your BMW’s infotainment system. If you’ve ruled out all the other issues, you may have to schedule a dealership visit so BMW’s technicians can update or repair the system’s software.

However, if you are not familiar or comfortable with these tasks, it is advisable to consult an auto professional who specializes in BMW 3 Series vehicles.

Prevention is Better Than Cure

Keeping your BMW E90’s audio system working optimally includes regular maintenance. Check the wiring and fuses regularly, keep the unit clean from dust, and update your radio software whenever BMW releases an update.

Warmed up and ready to troubleshoot your BMW E90 car radio issue? Remember, regular maintenance on all parts of your vehicle, including the radio, will result in a pleasurable drive every time!
