Tähän hätään löytyi Lontoon murteella ohjeistusta. Kääntyykö vai käännetäänkö :-)
The problem was a poor connection on the immobilizer anntena ring, this is round the ignition lock barrel.
You can gain access to it by removing the lower cover from the steering column.
The resistance of the coil should be 5 ohms +/- 10%
Check the coil resistance and the illimination lamp for poor contact.
Just removing the conection cleaning it and replacing it should do it.
Be careful not to damage the orange wiring to the air bag.
