I had a front-end collision and needed to have the radiator and a bunch of other things (throttle body, intake manifold, turbo cooler, starter) replaced just recently on my 06 GLI (73,000 miles). Some odd things are happening and I'm having trouble figuring out what is going wrong... thanks in advance for any help.
* The "STOP CAR! Check Coolant" message has appeared on the MFD twice since I got the car back. The first time, I stopped the car and checked and the coolant wasn't low. The second time (only a day later) it was about half an inch below the MIN line on the overflow reservoir
* The cooling fans are both working. But they stay on for a long time (10+ min) after I turn the car off. They have never stayed on for more than a few seconds in the past, even after summer driving with the AC on.
* I keep smelling coolant. Not inside the car, just outside. Basically whenever the cooling fans are running
* The temperature gauge is not showing anything above the normal 130F temp, driving or idle. I drove it for about 80 miles yesterday in the mountains and gave it plenty of opportunities to overheat
I suspect a leak but I don't see any obvious leaking on the ground after sitting overnight, so I am confused. Any thoughts? Is it normal for the coolant level to drop right away with the new radiator and to smell coolant?
