Hey guys, I just bought a used 2001 A4 1.8T Quattro. I don't know much about this car.

I was looking and found this. What is this yellowish thing? Should I be concerned?

 

Not being a smartass, but get some of it on your finger and smell it. That's part of your subframe, and shouldn't be leaking anything at all, let alone something important. Could be grease or part of a cheeseburger you ran over yesterday.

 

I actually have smelled it. It smelled like grease and no I haven't ran over anything which was that high up the ground. It looks like the previous owner used it as jack point (as you can see in the picture). Would that cause problems?

 

Looks like nothing to worry about

 

Yeah no worries, that hole is there to help locate the pads on a lift or jack
