Hello, I was on Monday with my car to the tuv. They could not connect to the car for ASU take-off and said that I should go to the workshop. Today I was at ATU and they could not connect their device either. Now I should drive to the Renault. Has someone an idea what it might be. With the error code reader you can connect to the car and read codes. It is BJ 2006 (OBD2) Thanks in advance
