    Auto-Scan Fault Codes

    Hi Folks,

    I'd like some advice on following up fault codes generated in a VCDS Auto-Scan log.
    Is there a website/person the log can be forwarded to for advice or should I visit my local VW Service Centre?

    Thank you "vdubmotorworx".

    All were apparent prior to my recent 30,000kms service.
    I was surprised/disappointed that the VW Service Centre did not identify or action them.

    The Nav fault is nothing to worry about, may be from when the Nav was fitted, but its sporadic and If you have no Nav issues then forget that one.

    But the ignition switch faults I have seen before, have you ever noticed that it radio turns itself on and off for no reason or the door locks working on there own??.

    Usually when this fault is logged the customer complaint is radio turning off whilst driving or auto locking working for no reason. Its the electronics part of the ignition switch that's faulty, basically telling the car you are pulling the key out of the ignition when you have not.

    Usually most techs will do a service and check fault codes, if there are faults and they don't seem to be related or important and the customer has not had any complaints then they should erase them when they exit the programme, looks like your tech was slack not to bother giving the car a clean fault log after the service.....

    Keep a eye on the radio, I've seen this fault on golf 5 and 6 and eos......VDUB.....

    Thanks for the diagnosis.

    I haven't had any radio issues but this may explain why the auto open function works intermittently when the key is removed from the ignition.

    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).
