Dears, i really appreciate if you suggest diagnosis steps that i can do for my car issue. I have a tiguan 2009 SEL and the EPC light and check engine lights are on. I scanned the codes and the below image will explain the codes. I am wondering if this is a cooling issue that is causing the throttle body malfunction or something else? I tested the electrical wires and plugs all seems good. Thank you in advance.
Looks like there was an issue in posting the image? Maybe if you could post the codes we might be able to help assist you.
