I have a 95 jetta III celeb edition. It's an automatic with a 2.0. I just recently bought it and got a good deal cause it wasn't running. I figured i needed an ECM. Piece of cake right? WRONG! I took it to a shop that had the euro hookups to run a diagnostic. The Shop said that all the Wires that should have power do and the grounds are good. They tested all the wiring in the harness to see if there was any shorts and didn't find any. So everyhting goin into the ECM is good but there is nothing coming out. So they said that is was a bad ECM. The engine has fuel and compression but no spark. The previous owner let the battery run dead when the alarm went off cause he couldn't get it 2 shut off. This activated the anti theft system but that has been diabled with the key in the door. I called the dealership and told them my specs and they tell me what i need but they give me the Bosch numbers "037 906 259D". everywhere online that I go only gives me two options to choose from. Either 258AA or 258AS. When I explain that to the dealership they have no clue and say that they don"t know what 1 I need So I'm stuck unless I wanna pay a grand for 1 from them. Help me to know the difference between 258AA and 258AS and which one I need. Or is it another problem all together. Thank You!!!
