Hi all, in July i purchased an Audi a5 2011 2.0 tfsi. My first audi car. As ive heard how reliable they are. 2 issues. Oil in the coolant. White and creamy around expansion reservoir cap and neck of tank. No water in the engine. Oil cap clean inside. Put on new expansion bottle today and G12 coolant to see if it was just in the old tank from a pervious problem . But after driving 10 miles new tank starting to go black inside. Any suggestions where to look for oil leak appreciated. 2nd issue. A pinging noise and a yellow cog on dash staying gearbox malfunction and you can continue driving. This happened 3 miles down the road. From collecting car. Then after a few miles goes off. Does this almost every time i drive it. Sometimes a few times. Sometimes as i start the car. Car drives fine. Any ideas. Or experience in this appreciated. Thankyou
