Thanks Mark08859. I did not see another microlite leak but it is still very early since the fixing has been done... Of course, the days after, I had another surprise into the motor compartment when I inspected for a leak. First, I have to say that it has been very cold out here these last days and nights. So I found blue liquid on the ground and all around the right hole of the front protective plastic under cover and also, frosted blue and white styrofoam like little bubbles near the headlight. I call the dealer service and they ask me to come righ away (they seem a little affraid of my problems now!). We finally discouvert a bizarre phenomena, as the windshield liquid from the headlights washers got into the motor compartment and partly froze right there just beneath the headlight while the rest got stucked on the plastic protector down there. Funny thing that happened because of three things: the extreme cold, the snow in front of the car (because it was snowing!) and water that was present because the car was coming out of the last repair and they wash and soap the microlite away all over the front of the motor compartment. Again, nobody had never seen something like that!
