Vauxhall Astra 1.8 1999 - Key sensor module assembly removal question #

Posted by Paul Howd on April 21, 2011, 7:06 pm

Year of Manufacture *: 1999
( Optional ) Engine Code or CC: 1.8 16v

I need to remove the sensor ring/module security device from around the ignition switch. In the past I have found that these come away with a gentle tug once the cowling is removed but this one seems unwilling to come free.

Is this a case of me not pulling hard enough or do I have to go through a more complex procedure on this model,(such as removing the lock barral which means removing the steering wheel(cos it obscures the access to the hole for releaseing the barrel retaining lug), which means removing the air bag etc etc etc! )

There are two versions of the immobiliser unit on the Astra,version 1 simply unclips as you were expecting,version 2 will not come off until you have removed the lock cylinder.So you do have to remove airbag(two torx screws) and steering wheel.It helps too if the column switches are unplugged.Its actually not that difficult,just a bit more time consuming.

Thanks for that, I had basically come to that conclusion I just wanted somebody else to confirm it!

I have Never had to remove a steering wheel on an astra to allow removal of the immobiliser module, some have metal shields around them that prise off easily with a screwdriver,

As david has said, there are 2 x versions, one pulls straight off, but the other type needs the barrel removing which usually means pressing the pin in which you can normally get to by removing the wiper switch.

"OR" you can use a stanley blade or sharp screwdriver around the edge of the barrel and cut off the locking tabs on the module that are stopping the module from pulling off.

H.T.H. Tony.
