Over the last few weeks we have noticed a strong burning smell coming from the engine and since I planned to do a service and oil change I thought nothing of it.
Today I came to do an oil change after having the engine running for a few minutes to get things warm, turned off, opened bonnet and could see light smoke coming from the engine and a horrible smell.
After looking, I see there a small leak towards the back as pictured. Does anyone know what this is and what needs to be done?
The car is an E90 320i Pre-LCI. Oil change went smooth!
