K-Lines: Two Ships Collide

Can anyone tell me which current vehicles on the market have two K-lines?
We now have a Phaeton here at the university. Does it already have two K-lines?

I assembled the adapter with two K-lines and it works well with one. Now I have a question about the other K-line.

I believe it started with the two K-lines in the Audi A4.

Boss.

Hi.

Connect the Phaeton now... if you've built my adapter suggestion 4.0 and the Phaeton has 2 K-lines.
(If such an electronic control unit can still manage with just 1 K-line - which car would then need 2 ?)
Then, depending on the specific control unit (STG), either the one or the other RXD LED should blink.

If that's the case, you know that...
- The Phaeton 2 K-Lines has...
- the separated RXD LEDs are functioning as intended.

Due to the latter, I would naturally be interested in the result .

P.S.: "Normal" engine displacement can also be replaced by a TDI .
