Hey guys there are a few things that happened and I am almost lost on what to do. I had just swapped my TR Sensor the night prior, but the following day, i was on the highway everything was running great, and out of nowhere my car loses all power. so i pull over and let it run for a second so I can hear it a little better. Sounds like its misfiring or missing, turn it off, turn it back on, same thing. Disconnect the battery for about 5 minutes reset the ECM. Turn it on, same thing. try to give it a little gas, wont go above 1100 rpm. idle off the highway about 500 meters to an offramp and call a wrecker. while sitting there it makes a loud grinding noise amidst the missing and misfiring so i turn it off. Turn it to acc so i can keep my AC going cause its a million degrees outside. car starts by turning it to ACC. Turn it off. Now it wont start at all. No VAG so cant get codes. Any Ideas?

Thanks.
