I have several problems with my E90 318i, and little knowledge. I was wondering if annyone could point me in the right direction?

• Smoke comes out of the AC-vent when the engine is warming up ...
• When the engine has idled for more than 2 minutes, grey/blue smoke flies out of the exhaust after reving a bit, as shown in the image.
• Smoke rises from under the engine, in the exhaust area when the engine is warming up
• Alle the smoke reeks of oil, so i dont suspect any coolant leaks

Other than that the car opperates good.
