Just picked up this 3 a few days ago. It has about 55k miles. I neglected to bring my flashlight, so I couldn't tell that the expansion tank was empty. I refilled the tank, and the tank level drops about 1/8-1/4" each day. I can also smell coolant after the car has reached operating temp. I'm not seeing any obvious signs of a leak from above, but I have not pulled the skid plate to inspect from below.

I've Googled this extensively, and found a handful of owners with this same issue, but haven't found a resolution

Before I get the car pressure tested, are there any common areas of coolant leaks on this generation?
