Noticed I was losing coolant when it's below freezing after car is off. Had water pump replaced. Still leaking coolant. Had thermostat replaced.

Hopefully not leaking coolant anymore - will have to check when weather gets cold again.

Update from Jun 24, 2017: UPDATE: Still losing coolant, but only on low-temperature days. Audi specialist mechanic said it's not the water pump or thermostat, but most likely the thermostat "flange" or cover.

Beautiful car, but man, it's running me dry. Recently found an oil leak, as well..

Last year was burning oil so I had to have pistons/rings replaced. This year thermostat need replaced. I WILL NEVER, EVER BUY AN AUDI AGAIN and neither will 3 other coworkers. We all have A4's and each one of us have spent 'STUPID' money keeping these cars driving!!!!! JUNK --- JUNK --- JUNK!! Buyer beware!!!! Nice looking cars but 'bend-over' if you need repairs!!!!!
