    Thread: Double check my diagnosis; having immobilizer issues & I think it's the door lock module

      This is a 2000 NB GLX (1.8T; APH), ATM

      I've been dealing with immobilizer issues off and on for a while now, without having completely diagnosed them. Usually the car wouldn't start, I would fiddle around with the key, let it sit for a few minutes, and then it would start. This happened most often in the late summer, usually when it was most humid and hot.

      It started happening again this past week or so, and then a couple days back it just stopped wanting to start altogether. Unfortunately it's in the parking garage at work, and I didn't have time to take my laptop up there and run a scan until tonight. After some reading and a conversation with a guy at a local shop, I decided it might be caused by the door lock module.

      I cleared all the codes again, and it still wouldn't start, so I looked at the door lock stuff, and it was reading the driver door as locked all the time (even when it was unlocked), but it was showing it opening and closing. the passenger door was reading accurately.

      I was looking at the DIY to fix all the solders and microswitches, but that's more than I would like to deal with time-wise, so I'm planning on replacing the door lock assembly in the morning.



      Here's my Autoscan (my SAI is going out, hence the emissions codes):

      I doubt it is the door lock module. With all the other codes showing up it looks like you have wiring/electrical issues. You need to start here:

      http://wiki.ross-tech.com/wiki/index...ry:Fault_Codes

      Look them all up and it will give you leads as to what may be going on here.

      yeah, however the combi pump (SAI) has been going out for a while, hence all the emissions codes.

      I replaced the power mirror switch with a heated mirror switch when I got the car 6 years ago (and a couple years before the immobilizer issue started), but I don't have heated mirrors, that covers those.

      I had to replace a coil pack last year, and it isn't the bolt-down kind, so it gets loose every once in a while, that covers the miss-fires.

      that leaves 18058, 17978, 01176, and 01329.

      after I cleared the codes the only one that recurred was 01176.

      Hello Yurko,

      Thank you for the scan data.

      wow, thanks, that's super helpful. I'm glad I checked this before I went to buy a new door lock module.

      I did have to replace the heater core a few years back, and that preceded the immobilizer issues, so coolant damaging the harness would make sense.

      I did look at the key measuring blocks as well, and it said the key was readable, but not programmed to the immobilizer, but that there are 2 keys saved. I assumed this was because the immobilizer was blocking startup, but now that you make the point about the door lock module, that conclusion might be incorrect.

      I haven't replaced the batteries in the switchblades in a while, could that address the issue?

      I had looked into the Immo delete (in fact I emailed you about doing it the other day). What additional security features are you referring to?

      Also, regarding the SAI, I've thrown codes for that in the past, so that's where that came from.
