My friend owns a '13 BMW X3 with the 2.0-liter turbocharged engine. It has about 50K miles on it and it has been properly maintained by the dealer. It recently developed a new sound. The dealer claims to have listened to it, as has another shop we use, and they can’t hear it. But we can hear it very clearly. Can I get a reality check?
- It seems related to engine RPM. The sound is a high-pitched whine. My gut tells me it is the turbocharger’s bearings. But I’m a worrier. We can hear it inside the cabin when we drive with the HVAC fan off and audio off. No codes according to the dealer. Is this the dreaded “just out of warranty” profitability-enhancement noise we are starting to hear? Or are we just nuts? Seriously considering trading this thing in for a new crossover before it bites. What would you do?
