Simon_CSK Posted February 15, 2019 Share Posted February 15, 2019 Have an immobiliser issue on my disco. It doesn't appear to want to turn off. I have replaced the receover in the ceiling with one I know works but still no joy. What else can it be? Quote Link to comment Share on other sites More sharing options...
Ally V8 Posted February 15, 2019 Share Posted February 15, 2019 Usually corroded wiring in the nearside A pillar behind the plastic trim panel. Also be aware that plips can lose their synch with the BCU and need re-synching with Testbook or Nanocom etc.(Ie,the RF system may still be working,can be tested by Testbook or Nanocom) Quote Link to comment Share on other sites More sharing options...

As long as you can't unlock with the fob the only way to remobilise it is to use the EKA code then once remobilised you can use a tester otherwise it won't comunicate with immobilised BCU Quote Link to comment Share on other sites More sharing options...
Simon_CSK Posted February 15, 2019 Author Share Posted February 15, 2019 Plan B then.I will change the ECU and BCU and try it that way as I have a spare. Thanks. Quote Link to comment Share on other sites More sharing options...
sierrafery Posted February 15, 2019 Share Posted February 15, 2019 Do you have paired fob to your spare BCU? cos if not you'll immobilise that too, or if you have tester it's enough to replace the BCU no need to change the ECM too Quote Link to comment Share on other sites More sharing options...
