Q On my wife’s 2006 Vauxhall Astra, the radio stays on and the chime when you open the driver’s door sounds after removing the ignition key. I am led to believe this is a common fault and have removed the ignition barrel and taken it apart to clean and lubricate it. When I had the barrel out, I pushed down on the plunger/switch that sits in the bottom of the barrel housing, which was free to move, but the radio stayed on and the chime still sounded whatever position the plunger was in. Is there a repair for this or do you have to renew the complete ignition housing? Craig Christie
A When the key is removed from the barrel, it should move the plunger in the ignition switch to disconnect the ancillary circuit which controls, among other things, the radio. Normally removing the ignition barrel, ensuring everything is free and checking the plunger is not broken, should remedy the problem. As you have removed the barrel and confirmed that there are no problems in this area, then it does sound as though you will need a new ignition switch. This should be available separately from the lock assembly (part number 90505912), but you will need to confirm this with your Vauxhall parts department.
