my 96 A6 Quattro has been popping up with problems and one i noticed was this yellowish stuff in my oil. Its all inside the oil compartment.
What is the problem and what would be the best thing to fix this?????
thanks!

 

Usually foamy yellow stuff in oil is moisture. You may have possible head gasket failure where water is mixing with oil.

 

Is it 1.yellowish or 2.creamy (yellow-white)?

In the case of

1=> Castrol Syntec (5-50) could be the culprit.

2.=> Crankcase ventilation is not properly functioning.

 

drain your oil and see what color it is... if that looks fine its most likely just condensation on the cap

 

Its kinda creamy yellow/white. Is there something i can do about it??? is it an urgent problem i need to fix???

 

Try seafoam

 

Most likely its not a problem, if you make short trips a lot condensation always builds up on the oil cap and dip stick. Its usually normal in cold climates. If when you drain the oil and you can visually see yellow in the drain pan then you might have a problem, but a little is ok.

 

oh ok. Thanks cause i do make a lot of short trips and i do live in New England. So its definitely cold right now. I also did my oil recently and didnt see it in the drain pan. So i think im safe. Thank you though!!!

 

i can already tell who listened to last week's Car Talk
