After having experienced a cracked expansion tank late last year which was replaced (along with the hoses), I'm now suddenly facing another coolant leak. Drove the car home yesterday, a roughly 100km trip, and parked it. No issues at all during the trip, or the days prior.
Today however, the moment I started the car I got a yellow coolant light in the dash. Checked the level, and it was WAY low, however the ground was dry. Now it's 28 degrees here, so it might have evaporated overnight, but I suspect coolant fluid would leave some residue at least. Anyways, I topped up the coolant and went off on some errands I needed to do.
After driving around 15km, coolant light comes on again. Pulled over, waited a bit, and checked level again. And you guessed it, it's way too low. Now this time there's some liquid visible on the undertray and dripping out the little hole in the center of the tray, but no clear indication where it came from. I know how much fluid I added, and given the short trip, I'd expect a clear trail or at least something literally spouting fluid, but no.
Checked the expansion tank, hoses and clamps, and everything seems fine. Exhaust is clear, no smoke, so at this time I don't suspect a headgasket failure.
Car is a 2006 3.0si with N52 engine.
Any tips on where to look, or what to diagnose? It's a daily driver, and is supposed to go on a 4000km trip in a few weeks, which has me a bit worried...
