BM54 Repair Case Study

We recently had a call from a (very stressed) customer who was experiencing no sound from her speakers in her BMW X5. Oddly, her husband's BMW E46 was also experiencing amplifier problems.

We asked the customer a few simple diagnostic questions such as:

  • Which speakers are not working?
  • Is your screen still working?
  • Do you have any sound (or no sound at all)?
  • Is the navigation working?
  • Do you have odd noises coming through the speakers?
  • Is the orange light on the radio illuminating?
  • After discussing the faults on both their BMW's, we asked them to view our bm54 removal instructions and asked them to fill out the online repair form. The units were sent to us next day and we asked our engineer to expedite the repair as we understood the family were really missing their music and sat nav. We repaired both BMW amplifiers on the day of receipt and they were sent back via DHL with Next Day delivery (24 hour service). At bm54.com, we pride ourselves on our super speedy next day bm54 repair service, and were delighted to hear that both units we diagnosed and repaired were back in the car with ease.
