Title: Engine start blocked by immobiliser
Post by: stuby115bhp on 27 October 2013, 11:38

Have an intermittent problem with immobiliser preventing engine start.  When this occurs it takes 4 or 5 attempts before normal starting is achieved. Tried changing key battery but still the same (both keys). When scanning it shows the following codes:
17978 engine start blocked by immobiliser intermittent
01176 key - signal to low intermittent.
Any ideas where to start with this one?

Knackered transponder in the key?

I suspect it could be this as well but both keys I have started playing up within a short space of time.  Could it be the ecu?  The car has a misfire as well at the moment could these problems be linked? I believe there is more than one ecu on the car would the same one control both engine and immobiliser?

get the car scanned.
take off the ignition switch cowling and give the connector with the green wire and bkack wire a push/wiggle
