Auto-Scan Fault Codes

Yeah, faulty ignition switches are common. Have done a few in Golf 6s.

It shouldn't give you any starting issues, but it'll more than likely show up a few odd-ball electrical issues like the radio turning off and on whenever it feels like it.

Is this the ignition barrel itself or an actual electrical part in the column?
I have same issue on a 2011 ED35

@webup: The " Terminal S" switch on the lock barrel doesn't actually participate in the starting process; it's a set of 2 x normally-open contacts at the very end of lock that close when the key is fully inserted into the barrel.

So, the Terminal S switch's purpose is to electrically sense the act of the driver physically inserting/withdrawing the shaft of the key. It's used by auxiliary systems like the door locks and the display on dash to confirm that the driver has removed the keys from the barrel when exiting the car (and for other things too)

The ignition barrel is the physical lock that converts the key profile into OFF, IGNITION- ON/OFF, ENGINE-ON/OFF positions and (depending on the model) it can include a multi-way electrical switch that converts these physical positions into corresponding electrical statuses. On some cars it can also include the sensing coil that reads the security aspects of the key (on the key fob part).
