AČIŪ. na taip, k-line dubliavimas.
Trūkūmų yra ar ne? Prilituoti ir palikti? Ar jungiklį? Gali kada nors maišyti?

Netikiu, kad nebus salutinio poveikio, klaidu nuskaitymui gal ir sueis, bet niuansai turi buti

Depending on equipment level, the "new" Audi A4 can have so many control modules in it that putting them all on the same ISO9141 bus (K-Line) would exceed some of the electrical characteristics allowed by the spec.    To get around this problem, the new A4 may have two K-lines.

Siaip buna specialus switch'as, nors zinant koks modulis ant kurios K-line galima gal ir paciam perjungineti:

The dealers' solution is to put a VAS-6017 adapter between the scan-tool and the car.  This device acts as an intelligent switch, making an automatic determination which K-Line a control module is connected to.
