The LED headlights on my A6 C7 do not flash on to high beam when the stalk is pulled towards the steering column or switch to high beam when the stalk is pushed away. The blue headlight indicator icon does come up on the dash.
OBD11 comes up with no errors.

On OBD11 i went into Central Electrics and did an output test. The screenshots are below:

Any ideas on what might bethe problem? Thanks

The fact you've had to electrical faults in quick succession would make me wonder if your battery is in the way out. As a dieing battery can often cause all sorts of electrical issues. 

Also I wonder if the headlight switch could be causing a problem or the stalk itself. 

I had an electrical specialist check out the issue. He says the headlight switch and the stalk are fine. The fact that the blue icon lights up on the dash indicates that there could be an issue wuth the signal being sent but not received by the high beam leds.

Has anyone come across a situation like this?

What's the cure? A replacement sensor? 

Finally got it sorted. Turns out the headlights were not coded correctly.

The technician downloaded the correct codes and all is well now!

Glad you got sorted and with an easy fix 🙂

Hi Denzil (again),

Sorry, missed this the first time around...

Having seen the screenshots now that would have been my first question - if the lights at high beam are reporting they're only using 25% of expected output/load then is the system expecting a high watt Halogen bulb rather than LEDs...? Are they coded correctly? (Were they switched out from Halogen to LED and not re-coded correctly?)

But you have found the answer now - glad you got it sorted.

Have you got used to the 'tyre rubbing' sound now at sharp turns/full lock...? (our first conversation some time ago)

 

Best Regards,

Tigger
