Perhaps the new turn signal/hazard light switch is the cause?
What exactly did you exchange, and from what source?

The turn signal switch with part number 1K0 953 513A was defective.
The GRA (Green Run Authorization) indicator turned off when the button was pressed and either the "+" or "-" button was touched on the instrument cluster (the green symbol).
Replaced by ..513 G.
The GRA (presumably a piece of equipment) started working again immediately after the new switch was installed.

If nothing else works and you can't find anything wrong, try reverting to the previous version as a test. There must be some kind of bug in there.
Is this part original?
Best regards.

Yes, it's a genuine VAG part. I also initially suspected a connection problem. After working on it, everything seemed to work again for a while, except for the key light, which always comes on but is supposed to only illuminate for 3 seconds.
I will also try troubleshooting and redoing things tomorrow if I don't find anything.
Ich schau noch mal im Tec Doc nach der Bestellnummer .. G.
According to my understanding, it should simply be a later version and work fine.

... it should turn off after 3 seconds. There is no equivalent "diesel memorial minute" like with the preheating process.
Best regards.

The part number 1K0 953 513 G9 B9 is the correct switch.
According to the manual on page 99: "When the ignition is turned on, this indicator light illuminates for approximately 3 seconds. If an unauthorized key is used, this indicator light (with the key symbol) will blink."
It actually worked a few times today without needing any extra thought.

Okay, the steering control unit 1K0 953 549 AF is out, and no pins were bent, nor are they bent now. There's no indication of poor contact as far as I can see.

Hi, I've been using the open-source steering controller for a while now, and it allows me to troubleshoot issues more easily. So far, I haven't encountered any problems.
I had now done the following:
Removed and reinstalled the left-side mirror assembly (LSG) and turn signal switch, including the coil and lighting module underneath. Ensured all connectors were firmly plugged in, including the one for the rear window defroster (ZAS).
nach Einbau ging zunächst einmal nicht zu starten.! No starter.
Dann Zündung aus, Fahrzeug verschlossen und wieder auf. Fehlerspeicher der Wefahrsperre ausgelesen- leer. It was always empty.
AI and turn signal/wiper switch without errors.
All keys have been recognized and start permission is granted.
The key indicator light in the ignition illuminates for only 5 seconds after starting the engine and then turns off. This is normal, although I hadn't noticed it before.
Starting the engine is now possible even while the key symbol is illuminated.
I suspect the problem might be either the ignition switch or the connector to it, which may not be making proper contact.
I was very careful when installing the turn signal lever and didn't force anything, so I'm somewhat discouraged to think that I might have made a mistake anyway.
The only mistake I see is that maybe the LSG wasn't completely disassembled.
I deactivated the always-recognized error for the xenon headlight leveling system because I believe it's not installed without xenon headlights. Or are you referring to the small knob on the light switch?

It doesn't seem normal that the key symbol stays illuminated for 5 seconds. You've correctly narrowed down the error range, but I would also include the cable coming from the ignition switch. The fact that disconnecting and reconnecting, and moving the wiring harness, has an effect, as you just observed, suggests a problem with that cable.
Can the switch in the ignition lock be replaced independently on your model? If so, I would replace it to rule out that as the cause of the problem.

I had also considered that. I'll check if the electrical part is separate; if it is, then it can be removed and replaced with a new one, as you said.

Das hatte ich auch schon überlegt, ich werde nachschauen ob der elektrische Teil separat ist, dann kommt der weg und neu, hast recht.

"I don't believe the E-part is sold separately for the Touran... I think it comes as a complete unit, including the ignition switch (without the cylinder), but it doesn't cost that much. The retaining screws are probably a bit harder to reach. You would need an angle drill to bore them out."

Okay, it's a complete set.
Today I tried to start the car, and it didn't work on the first attempt. I pushed something up slightly on the steering control unit and then back down, and it started right up.

Einmal an dem Lenksteuergerät etwas hochgedrückt und wieder runter, schon ging es wieder zu starten.

Then you'll know where to look... If you actually examine this junk with a bit of common sense, you might be surprised that it ever worked at all.

Possibly check the contact points and (if possible) inspect the control unit for cold solder joints.

The poor solder joints should appear paler and not so smooth and reflective. I had already looked for them with a magnifying glass in the sunlight during my first attempt.

Quote:

Die schlechten Lötpunkte müssten blasser und nicht so glatt spiegelnd erscheinen.

Around the outer edges of the solder joint, a very small gap or separation can be observed when viewed with a magnifying glass. If you have already disassembled the device and have access to the necessary equipment, I would recommend re-soldering any areas that appear questionable, if possible.

A steering column control unit doesn't cost a fortune on eBay.
Search for them and click on "completed listings" and "only sold items." This will give you a sense of the prices. Even the high-end models (if you have MFA) are often sold for less than €50. I recently saw one that ended up selling for just €18 (granted, it was a bargain).

I wouldn't bother reaching for the soldering iron again or getting frustrated with the lack of willingness to start.

Here, you can see the different versions and check which one still works for you: http://wiki.ross-tech.com/wiki/index.php/Steering_Wheel_Control_Module_Versions

Greetings.
Sure.

Here is the translation of the text from German to English:

"Guste" means "gust" in English. It refers to a sudden and strong gust of wind.
