What causes a burning smell in my Audi A4's engine?

I've noticed a strong burning smell coming from my Audi A4's engine. It seems to be happening more frequently. What could be causing this and how can I fix it?

The most likely cause of the burning smell is an oil leak. You should check the oil levels and see if there are any visible leaks. You may need to replace the gaskets or the oil filter. It's important to fix this issue as soon as possible to avoid any further damage to the engine.

Another common cause of a burning smell is a problem with the coolant system. You may have a leak or a faulty radiator. It's important to have this checked and repaired by a mechanic to avoid any overheating and potential engine damage.

If you recently got new tires, the burning smell could be coming from the new rubber wearing down. This is normal and should go away after a few hundred miles of driving.
