Ok so I was going to look @ the oil level & then noticed a foamy substance on the end of it.

Any Idea on what that can be?

What you see on your dip stick is possibly just condensation. Take off your oil cap and look under the cap and inside the valve cover. Are there any thick foamy oatmeal like substance or noticeable amounts of water? If your oil was saturated with coolant, you would be able to see it up there too. Check your coolant for oil.

Start the car with the cap off and keep an eye out for alot of bubbles. A large amount of bubbles is a sign of a bad head gasket. A couple here and there is just air in your cooling system. Coolant and Oil have several places they can mix. If you have a turbocharged Audi, the seals in the turbo can go bad and cause a mix of oil and coolant.

Overall if your car sounds fine, you dont see oatmeal, your not using coolant and oil in excessive amounts, dont have white smoke, and your turbo isnt whining you probably just have condensation in your dip stick. If you are overly concerned you can send a sample of your oil to a lab and have it tested for traces of coolant.

What you describe is typical of condensation mixing with some oil, looking like a creamy goo on your dipstick. Are you doing a lot of short trips? It's caused by lack of sufficient heat to dry out the condensation.

well I hope it's the short trips.

Mind you it's about 15km to work.
