Why does my BMW X5 emit a strange smell while driving?

I've noticed a weird odor coming from my BMW X5 while driving. It doesn't seem to be coming from the engine or exhaust. What could be causing this smell and how can I fix it?

There could be a few possible explanations for this strange smell. It's possible that there is a build-up of debris in your air conditioning system, causing a moldy odor. Another possibility could be a leaking fluid, which could indicate a potential issue with your engine or exhaust. It's best to take your BMW X5 to a mechanic to properly diagnose and fix the issue.

One common cause for a strange smell in a BMW X5 is a problem with the cabin air filter. This filter helps keep the air inside your vehicle clean and free of any strong odors. If the filter becomes dirty or clogged, it can cause unpleasant smells to linger inside your car. Consider replacing your cabin air filter to see if that helps eliminate the odor.

I had a similar issue with my own BMW X5 and it turned out to be a small oil leak. If your car is emitting a burning smell, it's possible that there is a leak in your engine that is causing oil to drip onto hot surfaces. This can create that distinctive burning smell. Take your car to a mechanic to have it checked out and repaired.
