Audi Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is XXXXX XXXXX I'm here to help get your problem solved. This is a common problem caused by a failed Coolant Temperature Sensor (CTS) but can also be caused by a bad thermostat. I would go ahead and replace the coolant temp sensor, here is a picture to help you locate. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
