- Oil leaks: If there is an oil leak somewhere in your engine, it can cause oil to vaporize and then condense on the inside of your car, leaving behind a black soot residue.
- Exhaust leaks: Similarly, if there is an exhaust leak, it can cause exhaust fumes to enter your car and leave behind a black soot residue.
- Air filter dirt: A dirty air filter can also cause black soot to build up inside your car, as the soot particles can pass through the filter and collect on the vents and dashboard.
- Brake dust: In some cases, brake dust can also find its way into your car and contribute to the build-up of black soot.
If you notice a significant amount of black soot inside your car, it's a good idea to have it checked out by a mechanic to determine the cause and prevent any potential engine damage.
