Engine Cooling problem
2002 Audi A2 4 cyl Front Wheel Drive Manual 80,000 miles
The light on the dash came on showing water engine water level low. I topped it up with water initiially, just over half a pint. I know it shouldn't lose water, question is what do I do next? Can it be fixed or is it a really expensive repair? I can't see any obvious signs of a leak.
