So I bought a 2003 volkswagen golf GLS TDI 1.9L . Had mechanic look over it and said it looked good so I had a oil change which at that time the did the replacement of the oil filter and put a new fuel pump replacement. The head gasket cover was leaking so had that fixed everything seemed fine then I had to go get the dreadful interlock device installed and after I got home the engine light came on an it popped up two codes glow plug cylinder 4 is not working and the tcm code so I have been trying to figure out a good diagram of the engine so I can find where this tcm is located so I can check the wires around the tcm. It's weird cause the car starts up good and an when taking it on the freeway seems to shift good so I'm not sure if this can be from the dang interlock or if this is something that is going to start making my gear slip. Any help would be great full. I'm also looking for a owner manual for this type of car but not sure where to find the right one
