ABC Leaking out the top of reservoir Cap/dipstick
So I got home today and parked the car in the alley because my brother was parked on my driveway. We BS'd for a bit and he left. I went to my car and noticed a huge puddle infront of the drivers side front wheel. I opened the hood thinking my new pump just crapped itself. I then noticed the fluid was coming out of the reservoir around the cap and the dipstick. The cap was a little loose but the dipstick was pushed out. I don't know if they put too much fluid in the system, or it burped out, or because I am lowered via module that it changes the volume of the system or its because the weather here is finally getting warm.
The car didn't sag nor did I get the dreaded red warning. I started the car and lifted it up via the button on the dash and everything looks good. I washed it out and went for a long drive. I popped the hood and it wasn`t leaking anymore. Has this ever happened to anyone of you?

This. It should overflow only if overfilled or abc pump malfunctions and fluid is pushed past valve blOcks and pump back into the res (the car will sag in this case).
My vote is they overfilled the res as there are two marks on the dipstick- one for hot and engine running and one for cold and engine off. Marks are in German only.

I drove the car this morning to work (0.5hr drive) and when I got to the parkade I popped the hood to make sure there was no leakage which there wasn't any. Also this morning before I drove the car, the car didn't sag nor was there any fluid on the ground. I'm hoping its just an isolated incident.

There is a small weep hole in the combined ABC cap/dip stick. If you look you will see it, about the size of a ball point pen tip.
Sounds like you were over filled or had air in the system that was back pressuring the reservoir. Keep and eye on it.
