Around a month ago I became the proud owner of a Beetle 1.8t. Drove it two days and check engine light came on with a misfire code...being a chick I don't know too much about cars but I did my research and found out it needed a new coil pack which I replaced myself. It was still doing the same thing....I drove to the parts store and purchased another coil pack and on my way home the temp light came on. I pulled over about 2 miles from my house...tried to let it cool down for a few mins then drove it home....the light stayed on. Pulled the code reader in and it was throwing a code having to do with the coolant sensor....bought one and had it replaced. Still over heating....more research..water pump. I bought a water pump and timing belt and took it to my mechanic. He called to let me know that he had taken the duct to the turbo off that it was full of oil. He said that may be the cause of it over heating and is waiting for me to let him know what I want to do with the car. So my question is...should I go ahead with the water pump and belt to see if thats the problem or replace turbo? Thank you in advance for any help!
