willmason 0 Posted March 31, 2005 Ive bought a Late VR6 in a rolling shell but the Immobiliser box is missing I have tried using my immobiliser out of my 16v and swapped the transponder around in the keys but this isnt working I have used VAG-COM to Diagnose it and it comes up with immobiliser unauthorised intermittent then a code. Does anyone have much experience with the factory Immobiliser who can help Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted March 31, 2005 That'll be why it's not starting. You might need a new transponder coil in the column but you say the immobiliser is missing? It shouldn't be as CP ECUs have the immobiliser hard coded into the ECU circuits. I don't think there is a seperate immobiliser box as such. Not too sure I'm afraid as I don't have a CP ECU. For info, AG ECUs (up to 94) are non immobilised, CP (95 on) are. Try a local auto electrician, they may be able to help. Quote Share this post Link to post Share on other sites
willmason 0 Posted March 31, 2005 Thanks! Yes its a CP ECU But fixed underneath the dash is a little box by the Spoiler control unit that the immobiliser coil plugs into and another plug that goes to the back of the fusebox Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted March 31, 2005 Ah OK, sounds like you need that box then, which must be a relay or two that shuts down the starter and ignition (spark) circuits. Sorry, I don't know any more than that. Quote Share this post Link to post Share on other sites
willmason 0 Posted April 2, 2005 I bought the License for VAG-COM and that Adapts the ECU to the Immobiliser Im only getting one fault now and thats the Engine speed sensor but that might be cos its not starting. I think I have a long way to go. Quote Share this post Link to post Share on other sites
corradokid 0 Posted April 2, 2005 Yeah i would imagine that the speed sensor code is coming up because the car isnt running. Quote Share this post Link to post Share on other sites
