Hi, I had a rock or something hit the exhaust flap wire plug and bust it. In the process of trying to get it apart or back together the two larger wires touched and sparked. At that point the glow plug light came on and shortly after a drive or two the particulate filter came on. Codes were throttle actuator valve and adblue heater. Well trip to vw and the replaced the throttle actuator and I am still getting ad blue heater codes. So what happened? Is there a fuse or did the short burn them both out? Is there something else to check? The dealer charged me $800 after said and done and still have heater issue. Any ideas will be most appreciated.
