I sourced a replacement Ignition Switch (TEG reader) online from Spain. The supplier confirmed by email the Ignition Switch was new (old stock), so I bought it.

I think I’ll continue to live with the problem, hoping the Ignition Switch doesn’t completely fail, before trading the Croma in for a newer car at a dealer, unless I can source a virgin replacement Ignition Switch.

Hi,
I'm sorry to hear this. Unfortunatly there is no such thing as "virgin" Croma security coded ECU. As I said in my last post the replacement ECU has to be programmed to your car at the factory. I don't think that the factory can re-programme them. The most anyone can do is to copy the data (or transfer the whole chip) from the old unit into a replacement one but the ability to do this depends on the exact chip used in the unit.
