Hi Guys , I have a 2014 a5 2.0tdi sline FWD , recently I noticed some staining where the car had been parked just small pools every now and again. It is some kind of oil i thought it was diesel at first because it was quite clear but its defo not diesel , i then thought steering rack but I've not lost any fluid, I've took the rear tray off the bottom this was soaking as was the linkage on the steering rack suggesting something higher up it look like it may be coming from the driveshaft area I've read somewhere there may be an oil seal is this accurate and where can I get one asap? Drivers side rhd. Any thoughts appreciated
