Turn Signal Malfunction

Hi, I've experienced an erratic behaviour and wonder if anyone got the same. When I was trying to signal to turn right, a three left blinker goes on first then normal right turn signal continues.

I know there are two steps for signal lever for each side indicator, first a soft signal (3 blinks) then if you continue to push the lever further, after a tactile click and continuous blink (hard signal) activates. But this situation if I go directly right hard signal (lever to fully further right) firstly a soft left (three blinks) then hard right.

My diagnosis is; there is something wrong with cabling or button of lever, it temporarily touches/buttons for a soft left. Anyone experienced something like that before?

(extremely sorry if I misinterpreted the situation hence English is not my native language, thanks in advance)

Info: 2009 TT MK2 8J, +200K km daily driven.

Same thing happened to me on my A3 (which has the same signal stalks/switches)...


Turned out all you have to do is remove and clean up the contacts inside the switch. The trick is you have to remove the steering wheel and the module/clockspring to get to the switch...Then you remove that and have to dismantle the switch. Mine looked okay visually but it was basically like microscopic wear particles that were causing the wrong contacts to...contact, which was causing the odd behaviour. Once I cleaned and lubricated the internals, and put it back together, the problem was gone.

If you need a reference, we have a pretty good collection of Workshop Manuals in the Knowledge Base that cover how to remove the steering wheel and indicator assembly. You can find them in the link below -
