A4 having problem with oil in the coolant
i am having a problem with oil going in my radiator system. if the resevoir gets low then the oil get in the coolant and lands in the resevoir. then this week it turned into something that looked like a frosty malt...the result is the engine over heating.. can anyone tell me where this oil comes from and why... I hope for the best..

We would have a better idea if you posted the year and engine type of you Audi. But from what you are describing, it sounds like it may be the oil cooler. It is located right above your oil filter. When it goes bad, oil and coolant mix and it sounds like you are losing coolant also? If so , how does your oil level look?

Step 2 Remove existing oil cooler
Remove existing oil cooler and coolant lines.
Remove the jam nut (8) from the threaded tube (5) that goes through the middle of the oil cooler (7). Then unscrew the threaded tube (5) for oil cooler. Use a vice grips or similar tool to unscrew the threaded tube. You can cut and reuse the original tube if you don't damage it. If you plan to cut it and reuse it, use care to not damage the threads when removing. Wrap threads with a towel or similar item to protect.
Remove the feed line and return hoses from the oil cooler. Using pliers, squeeze the clamps and slide them up and off the oil cooler. Then pull off both hoses. You will re-use the hose 058 121 058 A that goes from the throttle valve housing to the oil cooler. To be safe, you can purchase a new hose, although mine looked to be in good condition so I just reused it.
The oil cooler should basically fall off at this point.

Before changing out the oil cooler, go ahead and do a compression test; what you're describing is textbook head gasket. Do you get white smoke out of the exhaust? Do you run low on coolant? A compression test will tell you right off the bat, is simple to do, quick and inexpensive.
