Was battery. Started but I hadn't reconnected a part correctly and started seeing smoke smelling parrafin wax smell and started running rough then died. Would start run for a couple seconds and shut down. Walked away from the car came back walked away again got on a train abandoning it in San Diego on the street for two days but had prepared for the best. Got it stored in a shop for the holidays. TDI 101 Died wont start scenario 7 leaning toward the intake director valve, antitheft system, solnoid, fuel issue or a combined scenario and/or associated codes from these. IDK if I much want to post here but I'll probably continue though I think it prudent to study a repair manual to familiarize myself with the correct terminology for various components and systems before posting further. Anyone have Manual(s) to offer for sale and/or links to software?
The best manual would be a Bentley, you can get them online or maybe find someone who is selling one off for a good price. (Generally costs around $100 for the manual) Chilton or Haynes don't have the detail and if I remember correctly, don't have the diesel specific info. I have access to prodemand online which has oem info as well.
Does the check engine light and glow plugs light come on when you turn the key on?
An immobilizer issue will generally allow it to start every time, but it will die immediately and most times it will flash the immobilizer icon on the dash. I just had some fun with some cars with that issue. But if it doesn't start every time, I'd probably lean away from that.
Another possibility could be fuel issues. Most common of which would be air intrusion. (Note, the alh does not have a lift pump in the tank)
The hose from the fuel filter to the injection pump should be clear, check for air bubbles when cranking or running.
There should be 12 volts at the fuel cutoff switch at the end of the injection pump when the key is on. Those can fail, but it's not as common.
The intake director valve... I assume you're speaking of the anti shudder valve (asv). That one would be really easy to check. Pull the pipe off the end of the intake manifold and see if the valve is open. It should stay open, except for a little bit when you shut down. I would probably not suspect that, but it doesn't hurt to check.
I suppose you don't have vag-com? That would be the best tool to use in diagnosing your problem.
