I have 2002 VW New Beetle Turbo GLS and I recently had the timing belt and water pump replaced by my mechanic. Exactly a week later my red temp light came back on. I put coolant in the tank as it was low. Two weeks after replacing the TB and WP the red temp light came on again, so I put more coolant in and took it back to him to see if he could fix the problem. Obviously there is a leak but he couldn't determine where it was coming from because there was no residue on the ground below my "Suga." Well I have been paying close attention since then & I still dont see anything underneath. Lately I have noticed a smell, kinda sweet musk smell from my vents when I turn my A/C on, the smell disappears after about a minute. What could possibly be the problem? Has this happened to anyone? PLEASE HELP!!! I'm lost, and frustrated!!!
