I have a old 2001 Golf4 TDI AHF engine (VW RSA) , and recently I been hearing abit of a screech when applying brakes from the front right Tyre especially when the car is moving in reverse,So i thought I would remedy the situation with a little bit of brake cleaner just to get rid of the dust mud and grime that could have built up in it. after I sprayed and clean the brake system calipers pads and rotors, I saw something Odd, the pipe that leads to my inter-cooler has some oil in it that looks like its filled up with oil to the max or its leaking but it doesn't look proper,but I don't know if this is normal or I should be concerned since I am basically a newbie, So should I be concerned and get it checked out or am i safe for now?
