Default Gunk build up on oil cap

Hey everyone,

I have a 2008 A2 2.0 and when I take off the oil cap, there is a bunch of white gunk built up on it. I cleaned it all off and changed the oil and then checked a while later and the gunk is back. Any idea what this is? Is it normal?

i believe that's normal condensation buildup.

If you don't drive it much then there is not enough heat for a sufficient amount of time to blow this condensation out. I had this problem on a air cooled VW a long time ago. If this is not your case then you have an issue where water is getting into your oil. Most likely a head gasket or worse. Have it checked soon to be sure.

Default Gunk Build Up

Some build up like you mentioned is natural. My '07s been doing it since it was new, just a little white gunk on the oil filler cap. There was a long thread about this several months ago, you may want to check it.
